Official Journal of The British Horological Institute Ltd

After nearly two years employment withthe Institute I still consider myself fortu-nate to be working here at Upton Hall aspart of such a dedicated team. Your staff– and we are most definitely ‘your’ staff –are all incredibly passionate about theBHI even though, with the recent retire-ment of Alan Midleton FBHI, there isnow not a single horologist amongst us!So it’s good to know that, whenever weneed it, we can draw on the knowledgeand resources of our hard working direc-tors, trustees, tutors, examiners and volunteers. We thank each and every oneof them.

Having read Alan Midleton’s definitiveaccount of the history of the BHI in pre-vious editions of HJ, I am acutely awarethat, from its very inception, financeshave been a perennial problem for theInstitute. And I’m afraid that this stillremains the case. That’s why, as yourCEO, I become increasingly anxious atthis time of year. Will we hit our budgetforecast? How’s the cashflow holdingup? And how many of our members willrenew their subscriptions next year?

And it’s that last question which isalways the most difficult one to answer.But there are reasons to be positive.After many years of steady decline ourmembership figures appear to haveturned a corner. Whisper it quietly, butthe BHI is now attracting more membersthan it is losing. However, we need tomaintain this momentum.

When your renewal letter arrives wehope that you will find it easy to think ofmany positive reasons for renewing yourmembership. And altruism might wellbe one of those reasons – the BHI cer-tainly needs your goodwill.

But no membership organisationshould take its membership for granted.At the end of the day subscriptions are adiscretionary spend and, unfortunately,we are all still living in straightenedtimes. So, whether it’s the family or thebusiness budget which is being consid-ered, we know that we have to continueto provide you with value for money if wewish to retain your membership foranother year. Altruism alone will not be enough.

This need to provide value is one ofthe reasons why, for the past year, theInstitute has concentrated so heavily onstrengthening what we consider to beour two main membership benefits –The Horological Journal and your access toour training and education pro-grammes. Both of these have, we hope,benefitted from some much neededinvestment – of both time and money.But there is still a long way to go and thework has only just begun.

As an organisation the BHI’s aspira-tions remain high. But we will onlysucceed in meeting them if we can carryyou, the membership, with us. I’m opti-mistic. And I’m certain you are too.

Internal ThreadA tip for Mike Flannery – and anyoneelse trying to find the pitch of aninternal thread. Lightly taper a pieceof peg-wood (or dowel) so that thethin end just enters the hole. Screwthis into the hole as far as you canwithout breaking it! The screwthread will impress itself into thewood and you can then use the pitchgauge on the wood. This techniqueworks on both left- and right-handedthreads.

Galileo’s Pendulum-ControlledEscapement I would like to correct a minor pointmade by John Abrahams in his inter-esting letter (HJ August 2014). Theman chosen to build the model illus-trating the Galileo Escapement, builtfor the Circulation Department ofthe Science Museum for inclusion inone of its travelling exhibitions, wasthe Foreman of the EngineeringWorkshop, Mr Reg Martin. I was atthat time employed in the workshop,so I witnessed its construction; it wasa fairly close copy of the older oneheld in the Museum’s TimeMeasurement Collection. Trained inmechanical engineering rather thanhorology, Mr Martin chose to useinvolute gearing in his model. MrMartin worked on an early Brownand Sharpe universal millingmachine that is now, in retirement,preserved in the Museum’s Handand Machine Tool Collection.

The Trammel of ArchimedesIn a letter to the editor (HorologicalJournal, September 2014, p. 390) Isuggested that the trammel ofArchimedes might be adapted todrive the end of the hand of a watchor clock accurately around an ellipti-cal dial. I would have left it there, but,just as Pinoccio had Jiminy Cricket,so I have a daemon in the form of aLittle Red Hen, who asked “Whydon’t you do it yourself?” So I did!

The Trammel of Archimedes hastwo trammels, or shuttles, that areconstrained to move along intersect-ing tracks that are at right angles toone another, e.g. one horizontal andone vertical. A rigid rod links the

centre, A, of the shuttle on the verti-cal track, to the centre, B, of theother shuttle, so that the centres arealways the same distance apart. Whenthe shuttles move, a point on anextension of the rod, C, traces out anellipse with semi-major axis a = ACand semi-minor axis b = BC (figure1). This is the process of ‘tram-melling an ellipse’ familiar todraughtsmen.

The present problem is to drive theprocess with clockwork. The clue tothis comes from examining the lociof points on the rod between C andA. These loci are shown on Figure 1,with the loci in black (or red) corre-sponding to the points indicated onthe blue rod. As one moves from Ctowards A, the ellipse becomessmaller and more elongated until, atB, it becomes a horizontal line of

length 2AB. As one progressestowards A, the line becomes anellipse again, getting smaller andfatter until, at the mid-way pointbetween A and B it becomes a circle,which is what we need. I am temptedto examine what happens as onegoes further, including points furtherout than A and C, and to see whathappens when the tracks are not atright angles, but my Little Red Hentells me to stick to the matter inhand.

So a shaft rotating once an hourwith its axis at O, driving an arm withits end attached to M, the mid-pointbetween A and B, will cause the pointC to describe its ellipse. (The fact thatthe shaft will need to rotate counter-clockwise is but a minor inconve-nience.) We still need to know wherethe minute marks should be made. A

Figure 1

Figure 2



Letters

general point on the ellipse is (a sin t,b cos t), where t is an angularmeasure of time with one minute oftime corresponding to six degrees.Points for t = 6, 12, 18, …54 degrees,plotted on a piece of graph paper,give the minute marks. An interest-ing geometrical property is that, at alltimes, the rod will point in the samedirection as would a normal centredminute hand.

That is the theory, but how will itwork in practice? To make a clock-size version, I cut two mutually per-pendicular 4 mm by 90 mm slots in apiece of 1 mm brass plate to form thetracks. The shuttles are 12 mm long(to avoid going astray where thetracks intersect), slightly less than 4mm wide (for easy sliding) and a bitover 1 mm thick. They are sand-wiched between two wider andlonger pieces of brass that are pinnedto them to give an H cross-section.The ends are tapered to form a lead-in for when the shuttle crosses thecentre. Abors through the centres ofthe shuttles are connected at theback by a sturdy piece of brass with ahole in its centre where a pin on theend of the driving arm can enter. Therod on the front is a lighter piece ofbrass also connected to the shuttleabors and extending beyond them toform the minute hand (see Figure 2).

The driving arm was initiallyattached to a crank handle that couldbe turned by hand and, after a bit ofadjustment, this was found to rotateeasily with little resistance, and tomove the hand smoothly around theellipse. The next stage was to attachthe device to a clock. Since I had aturret clock to hand (as one does!)with the wrong end of the lead-offconveniently rotating anticlockwise, Iattached it to that (Figure 3). This

might not seem like too demandinga test as a turret clock might bethought to produce enough sparetorque to drive a tank. But I deliber-ately run mine with the minimumweight to avoid wear and to keepdown the noise of the ticking, so anyadditional load on the output endmight easily have stopped the clock.The clock didn’t stop and the deviceperforms just as hoped.

Now I have to figure out what to doabout the hour hand!

The ‘New’ Horological JournalThe Ipswich Branch Committeewould like to congratulate theInstitute and the ‘Journal Team’ forthe new-look Journal. Thechangeover circumstances have, weunderstand, been very difficult butthey have succeeded in producing a professional, attractive and read-able Journal.

Richard Curtis

I wrote in praise of the ‘old style’Horological Journal (the September2014 edition) and empathise withthose readers unhappy with the ‘newstyle’ presentation of the morerecent Journals, particularly theapparent vast white margins devoidof text.

I also sympathise with readers whofind some recent content overlymathematical, although an under-standing of ‘isochronism’ is surelyimportant for horologists.

The extensive use of mrad (millira-dian) rather than degrees as anangular measure ‘The Non-linearSpring’ articles, October andNovember editions, is perhaps oneexample where the author shouldcarefully consider his readership.Few may be familiar with the ‘radian’,but will be with ‘degrees’, despiteradians being used extensively andusefully in mathematics.

I have peer reviewed many poten-tial technical articles for HJ andwould urge authors to present theirwork, however complex, in a mannersuch that all our membership canunderstand and gain from it. Thismay mean frequent and simpleexplanations of the salient points,and perhaps fewer equations and

graphs.I subscribe to the NAWCC’s Clock

and Watch Bulletin (USA equivalent tothe HJ) and also the optional supple-ment Horological Science Newsletterwhich is primarily for those with amathematical interest in horology.Perhaps the BHI should consider asimilar optional quarterly supple-ment to the HJ for publication ofcomplex mathematical articles, orpublish them only on the BHIwebsite rather than in the HorologicalJournal.

Malcolm Pipes FBHI FIMechE

In the November edition ofHorological Journal variousletters commented both on thelayout and content of the previousedition.

Firstly it is certainly very necessaryto congratulate the multiplicity ofindividuals who succeeded in gettingthe September issue out to membersin the absence of the official editorand at the same time as a radicalchange of its format.

Reaction to the new typographyand layout of the HJ will be a matterof personal taste and cannot pleaseeveryone, personally while my agingabilities appreciate the clarity andreadability of the new edition mysense of nostalgia mourns the slightlyamateurish feel of an old friend.

Of more importance however arethe references and criticism of thecontent from GC Crabtree and MJWild. HJ has a difficult job in beingthe official voice of the BHI andcatering for the needs and interestsof the horological trade and both theprofessional and amateur individualmembers who have an incrediblywide range of skills and abilities.Balancing these competing require-ments is not an easy task and if therecent dissension is anything to go bythen the official editor’s abilities inpreviously achieving this over anumber of years has been well

Chairman Ray Walford believes thata combination of things made it arecord-breaking event. Firstly, theBHI was lucky enough to have ‘TheGREAT Britain Watch’ by RogerSmith FBHI on display in theGeorge Daniels room and secondly,Alan Midleton FBHI, had made atelevision appearance a few daysbeforehand flagging up the event.

‘It really was an excellent day,’ saidRay. ‘It was lovely to see Upton Hallfull to bursting with so many peopleenjoying themselves. As always itcouldn’t be done without the armyof willing volunteers and I would liketo take this opportunity of thankingthem very much.’

With so many people at UptonHall, the Clock workshop wasextremely busy, much to the delightof volunteers Jim Arnfield FBHI,Norman Jacklin FBHI, Geoff WalkerFBHI and BHI Director, Nick Brown.

Jim said: ‘It was the first occasionfor us to reveal our new large screentelevision systems which have nowbeen fitted in both workshops. Themonitors will be invaluable on thehorological courses we run as theywill enable us to show demonstra-tions of close up machine work andother intricate procedures to groupsof people.’

‘At the Show we were gear cuttingto a very small scale (watch size) on aSchaublin 70 lathe, and the monitorenabled onlookers to have an excel-lent views – even better than usingtheir own eyes.’

Jim and his team were also onhand to discuss the work of the BHIConservation and MaintenanceGroup, which is run by volunteers tolook after the Upton Hall MuseumCollection.

Norman also took the opportunityto present an adaptor, which linksthe stepping motor, donated by theManchester branch, to the dividinghead of the Schaublin lathe, andprovide demonstrations of how it works.

This famous clock business, one of the BHI’s corpo-rate members, opened its doors to Barrie andRaymond (and their guests) in August for an after-noon full of activities.

Smith of Derby has always been a family businessand the visit was hosted by Mr Nicholas Smith who wasjoined by his son Jonathon, the latest in a long line of‘Smiths’. The pair quickly proceeded to enthral aneager audience with tales of the company’s rich her-itage and long service to the horological industry.

Mr Nick, as his staff affectionately call him, hasimmersed himself in the history of the company andimmediately engaged guests with stories from thechallenging 1800s right through to today’s organisa-tion and technologies. It was particularly apt, given thetiming of the visit, that he was able to touch on thepart played by Smith of Derby in supporting the wareffort from 1914 to 1918.

The guided tour took the visitors around the thor-oughly modern factory premises and included a stopin the traditional ‘workshop’, where the group couldsee at first-hand traditional conservation work beingcarried out, as well as the area in which new, exciting

projects for public timekeeping today were being con-ceived and executed.

Jane Arnold of Smith of Derby said: ‘It is accurate tosay that interest in turret clock making and restorationtoday is very much alive in the UK and further afield.Smith of Derby is very proud to be working closelywith the BHI in this incredibly important work’.

Barrie Fitton and Raymond Walford of the Lincolnshire Branch of the BHI wereamongst the lucky prize winners at this year’s BHI Annual Summer Show raffle;and their particular prize was a guided Tour of the Smith of Derby’s premises.

Occupation: Birmingham University Studentand BHI Student

What inspired your interest inHorology? Having become disillusioned witheducation and leaving early, I cameto Horology as a second career; awelcomed opportunity to learnsomething that I was passionateabout. Watches have always inter-ested me, as a child I used to stareinto shop windows, pining over themost expensive and exquisitewatches. I soon adopted a quirkystyle; my first watch was a square

water resistant creation, not exactlythe features I now desire in a watch!

When opting for a career change,I was torn between an airline pilotand further pursuing my passion inhorology. The deciding factor wasprice, I believed horology would bethe less expensive option; little didI know! Then, about four years ago,I looked into scholarships for Swisscourses to find that they were onlyoffered to employees. It was thenthat I first heard of the opportuni-ties available at Birmingham CityUniversity which offered studyoptions; this soon became a BADegree Course.

I understand that alongside thisDegree you are also jugglingBHI Diploma Qualifications,how are you finding the com-bined learning experience? It is time consuming and requiresdedication and long hours of hardwork, but I think it provides thebest learning opportunities. Forme, the academic style of thedegree is complemented by thevocational style of the BHI DistanceLearning Course. With the latter, Iwas motivated to set up my ownworkshop to enhance practiceopportunities. I enjoy the freedomand often find myself off on a newproject given the autonomy to

choose the watches that I repair. Ihave just submitted my first piece ofexamined work using solely theequipment I have in my workshop.Learning through repetition hasproved encouraging; I am con-stantly building my portfolio.

What is your particular area ofinterest? Both courses I am undertaking arebased on the study of watches; thisis where my passion has alwaysbeen. I believe that even in themodern world, a simple mechani-cal watch will always fascinate andthat as a piece of jewellery it pro-vides an opportunity to expressone’s character. For example, myfirst square watch was highlyunusual; in this way, it showed that Ilike to challenge the status quo.

Where do you see yourself infive years? I have one more year atBirmingham City University andafter that the future is uncertain. I aspire to own my own Brand whichwill create handmade luxurywatches full of character and charm,sourced entirely from England. Inreality, the next five years will con-tinue to see money pumped intoimproving my workshop!

Meet the StudentIn our continuing, occasional series of Meet the Student, Harriet Olivia talks to Martin Cleaton to find out what motivates him.

East of Scotland Branch Visit Upton HallTowards the end of October, nine members of the Eastof Scotland Branch paid a three day visit to UptonHall. Most had visited sometime in the past … somethe distant past. The long journey was well rewardedwith Alan Middleton giving a guided tour of the collec-tion and Briony giving the history of Upton Hall on thefirst day. The second day saw the group visit the UsherCollection, Lincoln, plus the Newark Air Museum. Onthe final day, Jim Arnfield held the group captivatedwith his legendary horological tales in the clock andwatch workshops – not to mention the same in theCross Keys pub the night before. Thanks to the UptonHall staff for hosting us and to Zen Chowaniec (photo,third left) for organising the trip.



Midlands Model EngineeringExhibition 2014

James Buxton IEng MIED

I am not sure whether the show wasmore crowded on the day Iattended or there was rather lessgangway space between stands. Iremember a trade show at theHanover Messe in the late sixties.

All the stands were single aspectand in well spaced ranks. It made itso easy to know where you were.There was huge space in the gang-ways and after an initial wizz up anddown each row you knew you hadpassed every exhibitor. Havingmade a note of all of interest, areturn visit to a particular exhibitorwas very easy and straightforward.

So, was there much of interest towe horologists? Not in number, butcertainly in quality and interest. Myhabit is first to see what has beenentered into the ‘Horological &Scientific’ competition class. This isusually a worthwhile stop and wasvery much up to scratch this year.Although there were just twoexhibits/entrants, they were bothwell worth their awards. First prizewas awarded to Wally Brown for hisMusical Clock movement to ClaudeB Reeve’s design, Photograph 1.

Although the ‘words and music’as published, are comprehensive,this is not a project to be under-taken lightly. But, it will surely be amagnificent piece when it is com-plete, to say nothing of the com-plexity of the system. It has 18 bellsstruck from hammers driven fromtwo pin barrels. It will be good tosee the completed clock, when it allcomes together. A project that isnothing if not mighty!

Second place went to Phil Allingfor his version of W R (Bill) Smith’sskeleton Lyre Clock, Photograph 2.I am not as familiar with this ‘big’clock as with some others but I havefollowed another of Bill Smith’sclocks. Just to make things interest-ing, as an American, he specifies

threads other than BA! Phil hasdone well; the crossings were wellexecuted as far as it was possible totell under the glass hood. Thechapter ring was pierced from asubstantial piece which made the individual characters seemrather chunky.

Sometimes competition entriesare retained on the stands of theirhome clubs, so I find it is alwaysworth a look behind the locomo-tives to the shelves above. On thestand of the Bromsgrove Society ofModel Engineers was a representa-tion by, I believe, Martin Sheridanof John Harrison’s RAS Regulator,Photograph 3. I don’t think this wasentered for competition, but it wasa delightful example of somethingdifferent from the prevalent‘steam’. In my own local modelengineer club, steam is definitelyking but clocks are welcomed tobring something different. Welldone Bromsgrove.

Once again we have to raise ourhats to the Milton Keynes branchwhose contribution was anotherwonderful exercise. In the recentpast their stand had depicted thestory of time measurement andthen the fun that can be had fromtime indicators. This time they hadestablished an ‘Olde Clock Shop’;what a splendid effort! The ‘shop’was teeming with the sort of equip-ment and tooling that might havebeen found in the workshop of anineteenth century clockmaker.How they must have raidedmembers collections to have beenable to pull together such an array!Full marks, once again.

The British Horological InstituteIf it closed tomorrow, would anyone notice?

E. Peters

IntroductionThe question is not an idle one, given that as recently asfour years ago, the British Horological Federation(with offices in Upton Hall) was wound up after eigh-teen years. Having said this, the question has anobvious answer in that around 2,500 people wouldnotice the absence of a monthly HJ if it ceased to landon the doormat. However, I suspect that the real ques-tions should be; if the BHI suddenly ceased to exist,would there be a vacuum? And would some otherorganisation step in to take over what the BHI currentlydelivers? We believe the answer to both questions is anemphatic yes. And I give the following reasons.

The BHI CommunityBy its very nature, horology is a solitary occupation andcan be a lonely one. Membership of the BHI offers amonthly journal through which members can connectwith developments and ideas in the horological worldas well as a sense of belonging to a community of like-minded individuals. In addition, the Branches withtheir regular meetings and outings give an opportunityto socialise and learn at the same time. If the BHIceased to exist, this ’community’ would come to anend; although many Branches might well continueindependently for a while at least.

As an alternative, the excellent AntiquarianHorological Society (AHS) has Sections throughoutthe UK where meetings take place and former BHImembers might join this society instead; many indeedare already AHS members. However, the AHS has morein common with a Society of Antiquaries than with apractical/professional organisation and, as a place todiscuss trade or professional matters, would not reallybe a substitute for a BHI Branch.

The Horological JournalThe HJ has a unique place within horological literaturein the UK, covering historical and contemporary sub-jects as well as future trends. Its content is part profes-sional/trade and part amateur and includes much ofpractical use and instruction to professional andamateur alike. The correspondence pages are certainlythe ‘liveliest’ of any in the horological press and, often,as much can be learned from a member’s letter as canbe found in the article that provoked it. It is not anexclusively learned journal, like the AHS’s AntiquarianHorology, nor yet a magazine devoted almost entirely to

antique clocks, like Clocks magazine; and it is certainlynot like one of the more glossy watch journals, all ofwhich are excellent in their way, but have a perspectivelargely confined to the modern watch industry. Thenearest equivalent to the HJ is probably the AmericanNAWCC Bulletin, published six times a year – althougheven this confines itself to historical subjects.

If the HJ suddenly ceased to be published, would anyof the above magazines take on its current content?(NB. I have not contacted any of the journals named below buthave drawn conclusions from reading recent editions). TheAHS would always be interested in publishing historicalarticles, although I suspect they are rather more choosyin what they accept. Clocks magazine would similarlypublish historical articles, but possibly not those onwatch subjects. Clocks would also take on the articles onpractical instruction but, again, not those involvingwatches. The specialist watch journals tend to concen-trate on the modern watch industry so would havesmall interest in much that is published in the currentHJ and certainly nothing involving practical instruction.

From this it can be seen that the loss of the HJ wouldbe a major blow to the horological community, bothprofessional and non-professional. By contrast, the lossof some other horological publication may not havequite so much impact.

The BHI Education Programme From its foundation, the BHI has put education at thecentre of its raison d’etre, beginning with the eradica-tion of the secrecy that surrounded the trade inVictorian times. Since then, we established the firsthorological technical college in Clerkenwell and, in the20th century, supported several colleges in teachingour programme. We also developed a DistanceLearning Course (initially called the CorrespondenceCourse), all of this leading up to the award of a recog-nised professional qualification. As the collegesdropped our course one after another from the 1980sonwards, interest in the DLC has grown accordingly;which confirms to my mind that it was not a lack ofinterest from potential students that led to the declinein teaching but more to do with internal college priorities.

Combined with the DLC are the short courses thatare run at Upton Hall. These either support the DLCor can be attended by interested amateurs.

From time to time every organisation should question whether it has outgrown itsusefulness. Although we are immensely proud of the fact that the BHI has nowbeen in existence for over 156 years and we continue to plan for the future, what ifour members deserted us? Or our finances took a disastrous turn for the worse?Would our demise be lamented?



If this education programme was to end, it would bedifficult to see where a new generation of horologistswould go to acquire an education leading to profes-sional status. It is very unlikely that the colleges wouldreintroduce our course into their programme.Birmingham and Epping Forest would no doubt con-tinue to run their horological training but would prob-ably struggle to cope with the increase in demand if theBHI suddenly ceased to exist. As for organising a BHIstyle education programme, it is difficult to see any ofthe other horological organisations in the UK beingeither willing or able to do so.

Without the BHI, there is always the WOSTEP course(but in practical terms this only deals with the modernSwiss watch) or West Dean College (but it is only con-cerned with antique clocks). But the BHI courseremains the only comprehensive horological educationalprogramme available in the UK; its loss would leave agaping hole which would be difficult to fill.

The Museum and LibraryHand in hand with the education programme is theBHI museum and library which was begun so that stu-dents/apprentices could have real artefacts and litera-ture to study in order to help them understand thework of the great and not so great masters and crafts-men of the past and the present, and thus encouragethem further their own careers. (NB. This was part of agreat museum expansion begun in the early 19th centurywhere every major factory was encouraged to form a collectionfor the education of their workforce). During 150 plusyears, the BHI museum has grown to the point whereits collection now numbers around 2,500 artefacts,many of which are of great historical, artistic, techno-logical and social interest; interest that goes beyondthe horological enthusiast and which appeals to amuch wider audience (see HJ September 2014, pages458-461).

During the past thirty years, all museums have comeunder financial pressures and this has led to theclosure of many. Like other disciplines, specialisthorological museums have been hard hit with some,for example Bury St Edmunds and Prescot, closingdown altogether. The BHI museum is one of theshrinking few that remains intact and accessible andtrue to its original purpose. The loss of the BHImuseum, would impoverish our horological heritageand deprive both our members and the public of theopportunity to see and study a wide collection of realhorological artefacts. In a world where so much learn-ing is confined to what can be displayed on a com-puter screen, I believe this counts for something. It isalso worth noting that BHI members have more privi-leged access to the BHI museum and library thanmembers of the public.

The BHI library is, perhaps, an even greater assetand it contains volumes and papers that are uniqueand thus irreplaceable. In my opinion and theopinion of others, it is the finest horological library inthe UK. The disappearance or dispersal would be aminor cultural catastrophe.

Thankfully the museum and library are in the careof a separate charitable trust; but this trust continuesto rely on support provided by the BHI (primarily the

use of Upton Hall) for its survival. Would any otherorganisation take on the BHI museum and library ifthe BHI closed its doors?

Various British museums and libraries wouldundoubtedly select specific items for their collec-tions – but none, I suspect, would take them on intheir entirety. However, there may be museumsoutside the UK who may be willing do so and the BHIMuseum Trustees would certainly look into that possi-bility if it meant the complete collection and librarywould remain intact.

Having said all of this, there are a number of horol-ogists – some of our own members amongst them –who would actually like the museum and library to besold off. They usually do so for one of two reasons.

Firstly, they fail to understand the role of themuseum and library within the education programmeof the BHI, either for new students or for fully quali-fied and experienced professional horologists.Instead, they want the financial resources raised fromthe disposal of the collections to be put into otherareas of the Institute’s business.

Secondly, their reasons are rather more mercenary.The rarity and value of our museum and library issuch that certain persons would simply welcome theopportunity to acquire artefacts from either. In thepast such enquiries have been received.

ConclusionTo return to the central question: If the BHI ceased toexist, would anyone notice?

I hope that the above article proves that such a scenariowould be, at the very least, unfortunate for professionaland amateur members alike and a minor tragedy for thecultural life of the UK.

Without the BHI in existence, many Branch meetingswould continue independently – for a while at least. Muchof the content of the HJ would be taken over by otherhorological publications; but, equally, much contentwould also never get published. The DLC may possibly betaken over by another organisation but the loss of ourshort courses would be a serious blow. And as for themuseum and library, its dispersal or disposal, either in itsentirety or piecemeal, would be yet another blow to horo-logical heritage and research in the UK which would befelt increasingly over time (no pun intended!)



While the title of this month’s articlemay seem a bit odd, I have a validargument for making the abovestatement. Part of my yearly routinewhen preparing my car for thecoming winter, includes the installa-tion of winter tyres. As I pulled eachtyre out from its summer hideaway, Ilooked over the specificationsmoulded into the sidewall of thetyres and thought ‘That’s a goodidea, why aren’t watch balancesmarked this way?’ Having the specifi-cations clearly stamped on each tyre,means that if my tyres were evermixed up with others, they couldeasily be identified by looking at thesidewalls. I thought of this because arecent watch service didn’t end well;and I could have avoided the wholeaffair if only the calibre and beat ratewere engraved or marked on theunderside of the balance arm – outof sight – but available for quick ref-erence by any watchmaker. Here’swhat happened.

The vintage Patek Philippe 10"200 manual-wind movement arrivedin poor condition, and to my dismayit wasn’t running. Whenever a non-running watch shows up on the

bench, you are faced with a decision:do you take the watch in for serviceor not. Servicing a non-runningwatch is a risk, and the risk is greaterfor older watches where replace-ment parts are difficult or impossibleto find. It can also be a risk for newerwatches such as those from a manu-facturer that refuses to sell parts towatchmakers outside of their ownservice centres. A watch that isn’trunning is an unknown, it may onlyneed a good cleaning, or it may haveserious defects. You may spend a lotof time on the job, and in the endhave no success. I always tell my cus-tomer that there could be hiddendefects that won’t reveal themselvesuntil the movement is fully disassem-bled. I also emphasise that thedamage could be such as to renderthe movement beyond economicalrepair. If all of those concernsweren’t enough to discourage mefrom accepting a non-runningwatch, I am also aware that somedefects may only show up after theservicing is completed. There isnothing more discouraging thanhaving spent hours servicing andrepairing a movement, only to dis-

cover at the very end that you wastedyour time.

Have a look at photographs 1 and2 and you’ll see why the watch wasn’trunning, it was very dirty. The dirt,however, didn’t stand a chance in myultrasonic bath, and the movementcame out sparkling clean. I followedmy standard servicing routine, andwhen I was done and gave it a fullwind, the movement ran great with ahealthy amplitude at 19,800 beats-per-hour. Needless to say, I was veryhappy with the results. As is mynormal practice, the movement wasput to one side (without the dial andhands) to monitor its performanceover a few days.

The movement continued to runfine, so I went ahead and installedthe dial and hands and set the timeto my atomic standard. A while laterI glanced over and noticed that thetime was wrong; it was running fast. Ire-checked the movement on thetimer, and it showed a steady +5seconds/day. Thinking that initially Imay have set the minute hand incor-rectly, I re-set the time, doublechecking that it was accurate. A whilelater I looked over, and you guessedit, it was still fast. Something was def-initely wrong, but at this point Iwasn’t exactly sure what that some-thing was. I decided to compare therate of the Patek seconds hand to mytime standard. After the first minuteof my comparison, the Patek secondshand was 6 seconds faster than mystandard, at 2 minutes, the Patek was

12 seconds faster. That’s all I neededto see, I knew what was wrong.

Before going into anymore detailabout the cause of my fast runningmovement, I would like to offer achallenge to DLC students. If youare a DLC student and have com-pleted the module on trains andgear ratios, this would be a goodtime to stop reading. I have givenyou enough information to allowyou to figure out the problem. Whynot see if you can figure out what’sgoing on, keeping in mind that thehairspring isn’t touching anythingor sticking, and that the rate is asteady 19,800. When you have theanswer, continue reading to see ifyou got it right.

I needed to confirm my suspicionsso I let down the mainspring andremoved the train bridge. I countedthe number of teeth in the wheelsand pinions, starting from the centrewheel to the escape wheel. As youprobably figured out, the toothcount added up to an 18,000 train.An 18,000 train expects 5 beats forevery second, whereas a 19,800 trainruns at 5.5 beats per second. With a19,800 balance on an 18,000 train,the result is 30 extra beats for everyelapsed minute. Dividing the extra30 beats by 5 (the number of beatsper second in an 18,000 train) andyou end up with +6 seconds perminute, exactly what I observed.

How did this happen and whydidn’t the customer tell me? Ithappens because many of the samecalibre movements were producedwith two (or more) train counts,requiring different balances andtrain wheels. The customer didn’tknow because the watch wasn’trunning when he bought it. A subtleclue that something was wrong withthe balance was noticed during theservicing, see the damage to the hair-spring collet in Photograph 3.However, that damage alone wasn’tenough to cause me to think that thebalance was the wrong one for the movement.

Could the seller of the watch haveknown about this problem? Possible,but given that the watch wasn’trunning I doubt it. On the otherhand, it is also possible that the sellerhad someone work on the move-ment, and maybe they installed thewrong balance. I couldn’t find anyreliable data on this particular move-ment, which didn’t help me identify

exactly what was wrong; was it thebalance or the train? For all I know,maybe the train is wrong, or maybethe balance doesn’t even belong onthis calibre.

Of course the whole situationcould have been avoided, had I onlyknown the beat rate of the balancewithout having to service the move-ment. So now you know why mywinter tyres caused me to think ofthis watch. If the underside of thebalance arm was engraved with thecalibre number and beat rate, Icould have referred to it as soon as Istarted the service. Knowing the rateit only takes a few minutes to countthe train wheel teeth and comparethe two figures. If they don’t match, Iwould stop and not go any further.This would drastically reduce thetime that I had invested in the job,and the final cost to the customerwould be minimal.

Where does this leave me? I didthe work that I was asked to do andalthough the watch runs, it isn’tusable. I wasn’t able to source a newbalance, therefore I wasn’t able tosolve the problem; so how should Ibe compensated for my efforts?What have you done in similar situa-tions, because sooner or later thisscenario happens to all of us. Didyou bill the customer the normalquoted fee? Half the fee? Anotherpercentage of the fee? Or did youtake a complete loss on the jobbecause – through no fault of yourown – you weren’t able to fix thewatch (or clock).

Please take a moment and write tothe HJ with your thoughts. From a

purely business viewpoint, there isno flexibility, you should be compen-sated for your time, no matter theoutcome. What did I do? I billed thecustomer for my normal servicingfee; however, I did not bill him forthe extra work that went into thetroubleshooting and identificationof the fault.

After I sent this article in for publi-cation, the peer review process pro-vided me with more data on the10"200 movement.

1. The 10"200 natively beats at19,800 BPH, which of course meansthat the balance is correct but thatone or more of the wheels (likelyescape & fourth) had been replaced.How and why this happened willremain a mystery.

2. During the servicing I did notnotice any of the wheels looking anydifferent than any others, in otherwords, all the parts looked as if theybelonged together and the fact thatthe train ran perfectly free afterassembly does confirm that thewheels and pinions did engage andfunction properly. I don’t think I amalone when I say that part of my ser-vicing tasks does not include count-ing the leaves and teeth of thepinions and wheels and figuring outthe train count, you automaticallyassume that the movement has theright parts installed.

3. The hairspring was slightlydamaged and needed slight re-working. The squashed collet mayimply that the balance staff had beenincorrectly replaced, but everythingelse seemed to look fine and the studfitted into the stud carrier properly.

Making Harrison’s Late RegulatorPart 11

Colin Fergusson MBHI

The ratchetThis was fairly straightforward, although it is largerthan usual and has a recess bored in one side to accom-modate the bearing bush for the great wheel. Theturning and boring operations were carried out andthen the ratchet teeth were cut using a wheel-cuttingengine which I made some years ago. It is based on adesign that appeared in HJ in 1978 (figure 72). The flycutter was set using a centre (figure 73), there being nodraw to Harrison’s ratchets, and the wheel cut (figure74). Because there are two clicks, disposed at oppositesides of the great wheel, the click has an odd number ofteeth; 49. The point of this arrangement is that it pro-vides twice as many lockings per revolution, while theratchet teeth and clicks are larger and more robustthan would have been the case with a finer ratchet anda single click.

The barrelLike many of the parts of Harrison’s clock, this assem-bly is more complicated than the equivalent in a tradi-

tional longcase clock. It is made in three parts, thebarrel proper and two end caps which are attached bycountersunk screws. The barrel assembly is attached tothe ratchet by four long screws that pass through therear end cap, then through the flange on the arbor andinto threaded holes in the ratchet wheel.

When we investigated a source of suitable thick-walled tube from which to make the barrels, we foundthat it was more expensive than solid bar and sodecided to machine our barrels from solid. The bar wasbored to size and then glued to a mandrel for theoutside to be finished and the groove to be cut (figure75). The barrel was then released by gentle heat.

The front end cap was a straightforward turning job,but the rear one has an integral stop hook (figure 76) and so had to be sawn and filed to shape. The internal locating spigot was turned afterwards (figure77). The cap was attached to the barrel and then to the arbor and ratchet. The screws inside the barrel (figure78) were not easy to get at! The parts were assembled tocheck fits etc. (figure 79).

Making a Regulator to aNew Design

John Reynolds FBHI

MaterialsMost of the construction is in brassand it will pay to investigate how toobtain this as economically as possi-ble. Sheet brass is usually sold infour foot by two foot sheets, andalthough this is way too much tomake a single clock, it is by far themost economical way to buy it. Ifseveral people get together on thisproject, the cost of materials can bebrought down considerably. Forinstance, the current price of a fullsheet of 3 mm CZ120 engravingbrass from one stockist is £244.80,including VAT at 20%. This isequivalent to £30.60 per squarefoot. A single square foot willprovide all the 3mm brass neededfor this project with a bit to spare,but a single square of this size pur-chased from a stockist may costconsiderably more because ofcutting charges. Despite this extracost, it may be considered worth-while to obtain the plates shearedto size. The finished sizes of the 3 mm CZ120 brass plates are:

Front and back movement plates:140 mm x 190 mm

Mounting plate: 265 mm x 60 mm

If this option is being taken, anoff-cut of approximately 150 mm x100 mm of 3 mm CZ120 brass forother parts should be obtained.Where plates are being sheared,add on an extra millimetre to platedimensions as the edges areinclined to be slightly rounded offin the process. All that is thenrequired is to file up the edges tomake clean corners. The chancesare that the stockist will have cutthe plates ‘square’!

My next article in this series willcover making the wheels. TheCZ120 engraving brass required forthese is as follows:

Escape Wheel:75 mm x 75 mm of 16SWG or 1.5mm

Second Wheel:140 mm x 140 mm of 2 mm

Pinion Wheel:55 mm x 55 mm of 3 mm

Centre Wheel:85 mm x 85 mm of 16 SWG or 1.5 mm

Hour Disc:105 mm x 105 mm of 16 SWG or 1.5 mm

Brass rod, which is frequentlyused in clock making, is normallysold in 3 metre lengths. However,the stockists that I deal with price itby the metre and will supply it inshorter lengths. It is important toensure that the rod is machiningbrass because it is easy to confuse itwith riveting brass which has poormachining qualities – often com-pared with chewing gum! The brassrod can also be obtained at thisstage and the following quantitiesand sizes will provide plenty ofmaterial to be getting on with:

500 mm of 1⁄2", 9⁄16" and 3⁄8"diameter (for the pillars etc)

150 mm of 5⁄8" and 3⁄4" diameter (for the larger wheel seatings)

500 mm of 3⁄16", 1⁄4" and 5⁄16" diameter(for various other uses)

As in all clock making, be carefulto get the important dimensionscorrect, as some imperfections canonly be corrected by starting again(but it is amazing how many rejectedparts can be re-cycled in other pro-jects!). Consequently, it can be seenthat it is important to have morethan just enough material.

If it is proposed to obtain thewheels ready cut, then just the onesquare foot of 3 mm sheet and therod stock is all the brass that

needed for this project. A goodhelp is to have the second wheeland particularly the escape wheelcut for you. David Britten, who hasalso pioneered this clock, had thesetwo cut by Clarke and Jones, and Ihad second wheel the cut at thesame time. I cut the rest myself, buthis escape wheel was finer thanmine. I used a fly-cutter for thispurpose, but a Thornton typemulti-toothed dead-beat cutter wasno doubt used for his.

A little time then must be takenin sourcing materials; speak tofriends, get together, and enquireat the various metal stockists, but besure that all the sheet brass isCZ120 engraving brass and all therod is machining brass. As theseries progresses I will give furtherdetails and advice on the othermaterials needed. TheConstruction Series will begin innext month’s HJ.

I hope that many readers will take up the challenge to construct my new regulatorand to this end this short article provides information on the materials needed tomake a start.



New Record for Complicated Patek

The slight rhythmical bouncing ofhis slender dark suede brogue wasthe only hint that the otherwisesmooth and usually unflappableAurel Bacs might have been feelingjust a tiny bit of pressure. Eventually,his persistence (and the backing of some serious money by an anonymous companion on the line to him over his mobile phone)paid off when the hammer camedown in his favour at precisely 18:59Central European Time. The lot inquestion of course, was the intriguingPatek Philippe Henry GravesSupercomplication.

Until recently, Aurel would havebeen found on the other side of apodium, as erstwhile head of watchesat the rival Christie’s. No stranger toworld records, he was most recentlyactive when he sold a rare Rolexchronograph for over a milliondollars, after which he bowed out,retiring from Christies. His dramaticappearance in the saleroom atSotheby’s no doubt added to theprovenance of the ‘Graves Watch’that he had come to buy.

A repeat offender, as it were, theGraves Watch has had a history ofbreaking records. For the better partof its life it was the world’s most com-plicated watch, and when it last cameto market in 1999 (also by Sotheby’s),it smashed the world record as themost expensive timepiece ever sold.

The Sotheby’s sale in Geneva ofthis watch on 11 November this yeardemonstrated yet again the incredi-ble strength and dynamism of thewatch collecting fraternity. True toform, the Graves has more thandoubled its own record price, thistime selling for 23.2 million Swissfrancs (£15.1 million Sterling).

The sale in 1999 was due to theclosure and disposal of SethAtwood’s Time Museum collection.Atwood had purchased the watch in1969 from Reginald Fullerton,grandson of the original owner, the American industrialist, Henry Graves.

A stiff, unofficial rivalry had devel-

oped between Graves, in the earlypart of the 20th century, and thepotentate of American motor-cars,James Ward Packard. Both men wereinveterate collectors, amassing art,property, boats, etc, and throughoutthe great depression, each wasresponsible for commissioning veryexpensive complicated watches fromthe best makers in Europe, withPatek Philippe and CharlesFrodsham counted among thechosen. Graves was not to beoutdone after Packard ordered awatch with sky chart from Patek, andin 1925 he duly placed an order thatchallenged even Geneva’s best firm.

The watch was delivered to Gravesin New York seven years later inJanuary 1933, upon payment of$15,000 (at today’s value, a steal atunder a quarter million dollars).

In a beautifully circular set of cir-cumstances, the dials, one a beautifulcreamy-white enamel, and the otherin silvered gold, were made by Stern,the family of dial-makers who wenton to buy (and who still own) thePatek Philippe company.

Patek had invested the indepen-dent maker, Victorin Piguet, with theresponsibility of building the watch.

Piguet was a noted independentmaker of complications, and thishorological impresario at times hadthe entire watchmaking workforce ofthe Vallée de Joux working on theGraves watch.

Returning to Geneva in 2014, theexpectation of high drama was notleft unfulfilled. Bacs was pittedagainst a fellow European collector,present in the room. The startingprice of around 6 million Francs was,frankly, quickly dismissed, the pricerapidly rising to 13 million. Afterhushed whispers into his telephone,Bacs raised his paddle, offering anextra half-million. Bidding contin-ued this way for a time, with theincrements dropping at one stage to250,000 Francs. The pair continuedthis dance, pregnant pauses followedby ‘last-gasp’ bids with the gavel’sdescent already underway. At19,750,000, the rival bidder coun-tered with an offer of 19,999,999.Amid laughter and applause, othersin the room shouted out offers tostump up the extra Franc. With hiscompetitor finally spent, the watchwas dispatched in favour of Bacs andhis mystery companion for20,600,000 (before commission).

Many years ago when I was a youngapprentice and callow in the craft, Iused to boast loudly to the drawingoffice chaps that ‘if they could drawit, I could make it!’ All went welluntil some canny artist showed me adrawing of a man holding a four-legged open box. It was a small detailof a drawing called ‘Belvedere’, oneof a series of drawing called‘Impossible Constructions’ by M CEcher. The things he could draw, Icertainly could not make. Not onlywas my petard well and truly hoisted,I was hooked on Echer’s work. Forthose few who are not familiar withit, I suggest an internet search will betime well wasted. Like most geniuseshe was both bearded and left-handed, I need to make no furthercomment!

Now I am old, but sadly still callowin the craft, my boast has changed. Itis, more of a querulous whine ‘if Ican find my glasses and see it, andfurther if I can recognize it, then Imight possibly be able to do some-

thing with it’. I do not assert that Ican mend it, far from it, age hasgiven me an element of circumspec-tion, sadly far too late.

Seeing things clearly is becomingmore and more of a challenge.Bench View Towers is full of the‘new’ energy saving light bulbswhich, I am told, are pretty good atsaving energy. I have found, in prac-tice, they are pretty bad at being anygood at seeing things close up.

The need for a good moveable,multi-position light source in theworkshop has become more impor-tant as the years progress. I am notentirely happy with my workshop. Itis of course true that a bad workmanblames his or her tools and I am surethat a work person who blames hisor her workshop is a pretty badperson generally.

The workshop windows facedirectly south and there is nothing Ican do about it. This means thatduring most of the day it is verybright as the sun pours in. (I made

up that bit about the sun.) As mybenches are against the window Iam fighting a losing battle to seewhat I am working on as the sunlightputs the clock or other artifacts indirect shadow. I have blinds on thewindow but they really only seem tomake matters worse.

I have a couple of different multi-positioning lighting systems. One isa very old ‘Terry’s’ angle poise lampwhich I love for its design but it doestake up quite a bit of bench spacedue to the physical size of the lampshade. I also have a more modernsmall fluorescent tube desk lampwhich is impossible to focus andreally does not give much directlight, also the shade is too big forcomfort – it just gets in the way.

One of the other problems withboth lamps is that they do tend togive off a fair bit of heat which, whenyou are close up to them, can be dis-tracting. However help is at hand.

My friend Clive recently paid me avisit and while he was installing avery nifty Direct Read Out (DRO)system for me on to my Colchester,he used a very clever inspectionlamp made from a discarded mobilephone battery and a single ultra-bright LED. Clive is an electricalengineer par excellence and hisinspection lamp reminded me that Ihad seen another of his LED lightprojects a few years ago.

I had it in mind to make a simpleand adjustable lighting boom withthe LED clusters which are cheaplyavailable from most DIY outlets andoften used for down lighters. Theadvantage with using the clusters isthat they are physically quite smalland weigh very little, they also throwout a considerable amount of light.

I don’t think it worthwhile tryingto reinvent the wheel so I feel it isperfectly okay to copy good ideas –some call it a ‘homage’ which theypronounce in a faux French accent.So one Sunday afternoon I set aboutmaking a copy of an angle poiselight onto which I would graft anLED cluster.

1 will show that I have been moder-ately successful in this project.

I decided to make the arms out ofwood, I also think that aluminumstrip would have been a goodchoice. I quite like working in wood,it is very quick and easy and if youmake a mistake the scrap bits go intothe wood burner box and are notwasted. The wood is a length of 24mm x 12mm pine and the fixingsare 6mm diameter gutter bolts andwing nuts. I like gutter bolts as theyhave a square section just below thehead which will bite into the woodand provide a fairly positive yetmoveable joint.

On the Mark I version, I have usedsome springs and washers to providea bit more tension on the joints andto improve (I hoped) the flexibilityof the lamp holder. The springs thatI had in stock were not quite strongenough to take the weight of theLED cluster and the improvisedlamp shade, and really are coilbound and not doing what I hadintended. If I was to make a Mark IIversion I think I might increase thesurface areas of the joint sections toencourage a bit more friction. Thelamp shade also gave me a designproblem. Plastic flower pots and theoutside of a silicon sealant tube wereconsidered, as well as the standbymaterial of all Blue Peter fans – thecardboard inside of a toilet roll.These were all rejected. As the lampwas to be used over the bench whereI repair speedometers, I felt that touse the outside container of an oldspeedometer as the lamp shade wasquite apt, if not positively postironic, see Photograph 2.Incidentally the clever electronicmachine on the bench is anotherproduct of Clive’s fertile mine – it isan electronic speedometer calibra-tion machine.

One of the advantages of usingthe LEDs is that they are 12v and Iwas able to recycle a few other bitsthat I had in the workshop. Last yearthe alarm company changed thebattery in the house alarm and ofcourse I kept it. I used that sealedfor life battery to provide the powersource. I also have a very small solarbattery charger which keeps thebattery topped up. So while nothingin life is free, including the cheesein the mousetrap, this light does notcost much to run. When I was build-ing my workshop a few years ago I

had planned to install a 12 volt ringmain. I cannot remember why but Idid not do this at the time and I nowrather regret it.

The type of the LED cluster usedis a matter of personal choice, I didhave a couple of the surfacemounted LED clusters and whilethese give a good general light,which is very suitable for downlighters, they do not really provide afocused light. The LED cluster, eachwith four or five traditional LEDs in,do have that broad capacity. Theseclusters are a bit bigger but thatextra size is, I think, offset by thebetter light output, see Photograph3. The sockets for the LED clustersare available from most electroniccomponent shops, as are the lightclusters. I have added a small on/offswitch on the lamp shade. In termsof cost, the whole thing is less that

£10, however, if you have to buy abattery then the cost increases. Inmy experience there are lots ofrechargeable batteries to be had.Old rechargeable power tools wherethe batteries do not have the powerto run the tool will be perfectly ade-quate to power a small light. Thewhole thing is at the moment ‘G’clamped to a shelf above the benchas I have not quite decided the exactposition of the lamp boom.

As this lamp in operation hasproved to be successful I havedecided to replace the 240 lightbulb in the old angle poise lampwith a similar ultra-bright LEDsystem, again powered off a 12 voltsupply. I suppose to cover myself Ishould add that if you do not feelcompetent to wire up this devicethen you should consult a qualifiedelectrician.

Special guests including BHI President AnthonyRandall FBHI and Roger Smith FBHI were quick topraise the determination and dedication needed to become a horologist today, in front of the 150 strong audience of students, guests, speakers and demonstrators.

BHI Chairman Ray Walford began the proceedingsby welcoming everyone and saying that the day was acelebration for both new members of the BHI and stu-dents who have passed their exams.

He said: “Taking these exams is very hard work, thestandard required for theory and practical work is veryhigh – I would urge everyone to spare a thought for thestudents who have put in an awful lot of time andenergy to be here today.”

During the morning, guests had the chance to hearChief Examiner David Poole FBHI talk about ‘TheExaminations and Developments in Education’. Forexaminations, the emphasis was on the standardexpected from candidates to pass the servicing unit.Information giving requirements for success had been

circulated prior to the examinations and the talk illus-trated some of the difficulties which were experienced.As ever, the need for practice was identified as the key.

Students were encouraged to use the ‘ExaminationExercises’ section in the Distance Learning Course; inparticular, the facility to complete a ‘mock’ examina-tion paper when preparing for the examination. Whilethe presentation was taking place, others enjoyed aconducted tour of Upton Hall and The Collection byAlan Midleton FBHI.

BHI President Antony Randall FBHI gave a talk enti-tled ‘John Harrison H4’, looking at the life and work ofEngland’s most celebrated watchmaker and his worldrenowned watches, focusing particularly on H4. This wasfollowed with a Watch Demonstration by Alan BurtoftFBHI and Tom Keegan of the British School ofWatchmaking, who showed the procedure for adjustingEtachron arrangement for balance springs, the oiling ofshock resistant settings and lever escapement pallets. Asalways, it was an excellent demonstration and essentiallearning for the student preparing for examinations.

Hardworking horology students received the recognition they deserved at the BHI’sAwards Education and New Members’ Day on October 25.

Students and guests at Awards Day 2014.



After a buffet lunch, Rory McEvoy MBHI and TonySeabrook gave a fascinating account of the GreenwichTime Machine, describing the introduction of electri-cal timekeeping over the years – the original TIM ‘SixPips’ timekeeper is on permanent display at Upton Hall.

Roger Smith FBHI followed speaking about ‘TheGreat Britain Watch’ (see HJ March 2014) which was ondisplay in the Watch Gallery during the weekend.Roger, a protege of the late George Daniels, then wenton to talk about his own Isle of Man workshop – whichhe described as ‘complete watchmaking under oneroof’. All the watchmakers employed by Roger arecapable of making a watch from scratch following hisexacting designs.

Roger explained: “This gives the watchmaker a senseof ownership and pride in the watch they are makingand lifts the quality from high to extraordinary. Headded that it was a very unusual concept today withmost watchmakers being responsible for just a smallpart of the watch under production.

He went on to say that his Series II, which waslaunched in 2006, has seen around 60 ‘incredibly rareand different’ pieces made and sold worldwide.Another significant part of his business is the uniquecommissions he undertakes – around one every three years, and the all-important development work which will see Series III being released in the middle of next year.

The Keynote Address was given by Anthony RandallFBHI who started by congratulating all the students ontheir well-earned prizes and certificates.

He said: ‘The courses are not easy and you haveproved to yourselves, as well as to the examiners, thatyou can make the sacrifices and stick it out – not every-one can do that so this is a moment to savour.’

He went on to say that the purpose of the BHIcourses was to give a good general grounding on whichto build, but the one essential that they could not givewas experience and the only way to acquire that was topractise – and keep practising in the area in which youhave chosen to work.

Anthony encouraged students to continue adding totheir knowledge by making use of the large horological

bibliography and other sources of valuable informationthat is available

He said: ‘There are books on almost any subject youcan think of. The BHI library has an impressive selec-tion. I would also recommend that you join your localBHI branch, take part in the activities and get to knowyour fellow members. Most are more than willing tohelp if asked about a particular problem. If they don’tknow the answer themselves, the probably knowsomeone who does!’

He added that many local branches hold occasionalauctions of tools and equipment, providing an oppor-tunity to acquire ‘anything you lack at a knock downprice’. Valuable sources of information can be found inmuseum collections, such as the British Museum, theClockmakers Company, the National MaritimeMuseum and the Wallace Collection to name but a few.

He added: ‘Without the BHI as a focus there wouldbe no courses, or exams, or certificates, or prizes, or awonderful library, or a museum collection or theJournal, or anywhere to meet, or branch to join.Without all these facilities we would all be much thepoorer! Do bear that in mind when you hear criticismof the Institute, as you will – it’s all we’ve got and itsfuture depends on you!”

“During my lifetime there have certainly been manychanges and no doubt plenty more will come, but thebasic principles of horology remain the same. Thescience that lies behind the hardware has not changedand the basic materials of construction, steel, brass andcorundum, remain as they always have. Whatever youchoose to do I wish you well and gain much satisfactionin doing it.”

BHI Chairman Ray Walford then explained that the

Bronze medal winner 2014 Laura Turner (centre) with former recipientsPeter Naylor MBHI, Mathew Porton MBHI, Roger Smith FBHI and DavidPoole FBHI.

Chairman of the British Watch and Clock Makers Guild Award PaulRoberson FBHI present the Guild Award to Colin Andrews for theDiploma in Clock and Watch Servicing.



BHI would not exist without volunteers dedicating agreat deal of time to the Institute.

He said: ‘As an organisation we are very grateful tothese people, but we have not necessarily shown ourappreciation. I would now like to present five ‘specialawards’ to individuals for their dedicated service.’

Recipients were: Geoff Armitage MBHI, a formerdirector and vice chairman of the Institute; retiringdirectors Richard Snelling MBHI and Geoff WalkerFBHI, for their dedication and service; Paul ShrouderFBHI, a former Museum Trustee and organiser of thehighly successful Notts and Derbys Branch Auction,and finally to recently retired BHI curator AlanMidleton FBHI.

Students were then asked to come forward to receivetheir awards from Chairman Ray Walford, PresidentAnthony Randall, Education Director MartinWigglesworth and Chief Examiner David Poole.

Laura Turner was presented with the BHI BronzeMedal which is given to the candidate who has gainedthe best result in the highest level qualification. Shefollows a long line of very distinguished horologistswho have received this award.

She said: “It is a huge honour and very unexpected. Iam so grateful and I would like to thank the WorshipfulCompany of Clockmakers and the George Daniels’Educational Trust who provided bursaries withoutwhich I wouldn’t have been able to complete the

course. I would also like to thank my tutors atBirmingham City University, Jon Parker and JeremyHobbins and my fellow students for their support andsteady supply of Waggon Wheels!”

Chairman of the South London Branch GrenvilleJohns presented the Beresford Hutchinson SouthLondon Branch Prize for the best Portfolio in the Finalyear also to Laura Turner.

Chairman of the British Watch and ClockmakersGuild Paul Roberson presented the Guild Prize for thehighest overall result in the Diploma in Clock andWatch Servicing to Colin Andrews.

For a full list of other prize winners see HJ September2014.

A champagne toast closed the day’s proceedings.

Special awards in recognition of long and dedicated service to the BHI were presented by Ray Walford (centre) to Geoff Walker FBHI, RichardSnelling MBHI, Alan Midleton FBHI and Geoff Armitage MBHI.

Tom Keegan from the British School of Watchmaking gave a demon-stration of watchmaking skills, along with Alan Burtoft (not pictured).

‘As an organisation we are very grateful tothese people, but we have not necessarilyshown our appreciation. I would now liketo present five ‘special awards’ to individ-uals for their dedicated service.’

AMENDMENT The Malcolm Barrett Prize for the best Theory Paper Clocks/Watches was awarded to PAUL ASHTON

Bristol Branch

An excellent turnout of Branch members heard BillSunderland, supported by Chris Lowe FBHI, speak to uson ‘A one second verge pendulum clock’ at October’smeeting. Bill initially outlined the work of Galileo, theItalian physicist who played such a major role in theScientific revolution, and who in 1610, supported theview that it is the sun which is at the centre of our solarsystem. Galileo claimed, slightly incorrectly, that a pen-dulum’s swing is isochronous, but this was later cor-rected by Christiaan Huygens a Dutch mathematicianwho helped found the French ’Academie des Sciences’.

Huygens worked with the Academy’s official clock-maker Isaac Thuret, and associated with the Danishastronomer Ole Romer, who was a professor of astron-omy at the University of Copenhagen.

In 2004, Bill visited the Dutch exhibition the ‘Huygenslegacy’ at the royal palace ‘Het Loo’ which displayed anamazing collection of horological masterpieces, theexhibition being focused on work carried out around1657 by Huygens in regulating clock mechanisms usinga pendulum. An article in Antiquarian Horology March2008, ‘A pendulum clock owned by Danish astronomerOle Romer’ furthered Bill’s interest in building his ownone-second verge pendulum clock.

Such clocks are extremely rare and we all admiredBill’s exceptional passion and persistence in researchingthe very sparse information available. Rather than usemodern materials, machines and equipment, Bill, Chris,and other craftsmen learnt and used traditional seven-teenth century methods, commissioning cast brass forexample in building their clock, which is very closelybased upon that owned by Romer around 1672.

Work on the escapement brought major problems, theweight of the pendulum bob, driving weight, and palletlength and drop were all found to be critical in estab-lishing a correct action, but after several false starts andadjustments, the clock, using cycloidal cheeks and a silksuspension, ran excellently and gives a surprisingly accu-rate rate of within one minute per day.

The case was made by case-maker Chris Ayres usingwalnut veneer on a carcass of old oak, distressed to giveit the appearance of an old clock; the motif cartouche

covering the drive pulley proudly carries the‘Sunderland’ coat of arms, whereas the original clockowned by Romer, the ‘Romer’ family coat of arms.

Bill’s clock is shown in the photograph where thesuperb dial work can be seen; it had been set intomotion running accurately and perfectly throughouthis talk.

Bill had also brought along a second clock for us tosee, a diminutive lantern clock only eight inches high,possibly used by King Charles 1st, and possibly made byJohn Cattle around 1640, but lack of time prevented acomplete presentation.

Bill and Chris previously spoke to our Branch onlantern clocks some three years ago; many thanks tothem for their latest talk which was presented in thesame superb professional manner as the first.

Malcolm Pipes

East of Scotland Branch On a bright Autumn day, our October meeting at theCannons’ Gait, Edinburgh, started with a discussion ofour forthcoming auction sale. To avoid bringing all thesale items to the venue, our events secretary ZenChowaniec has produced a detailed online cataloguewith photographs and descriptions of each item, whichbidders can study beforehand.

After this was settled, Secretary Ashley Strachan gavea wonderful talk about his visit to Japan earlier this yearwhich was reported in HJ September 2014. Using bothstills and video clips, he illustrated the 22 day epicjourney visiting many museums shrines and gardens.His Japanese hosts clearly made him very welcome andhe cannot wait to visit Japan again.

Included in his talk were details of Japanese karakuriautomata which included an amazing warrior, firingminiature arrows at a target, and a little clockwork dollwhich appears to walk round a table, serve a cup of teaand return. Ashley has made a working model of thiskarakuri mechanism, which he demonstrated at theend of a truly fascinating talk.

Leicester Branch At October’s meeting, Dr Tim Treffry HonFBHI gave usa talk entitled ‘Advances in Watch Design’ and sub-

Bill Sunderland and Chris Lowe FBHI

Tim Treffry HonFBHI



Branch Reports

titled ‘Studied Simplicity to Leading-Edge Technology’.He promised to show us some remarkable watches andduring the evening certainly kept his promise.

Tim’s starting point was the Ulysse Nardin watch ‘TheFreak’ of 2001, which was designed by Ludwig Öchslin.This watch used an epicyclic train, the whole of whichrotated. It was one of the first in which silicon was used.It employed a double-wheel escapement in whichsilicon parts were used to provide wheels of very lowinertia. The techniques used to produce the parts weresimilar to those used in the semiconductor industry.

Diverting slightly, Tim told us about the InternationalHorological Museum in La Chaux-de-Fonds, which ishoused in a former nuclear shelter; probably the mostsecure museum ever. Ludwig Öchslin’s 2005 watch,designed for the museum while he was in charge of it,had an annual calendar and was characterised byextreme clarity and simplicity of display. Tim explainedthe mechanism of the calendar, which is very inge-nious. In 2006, Ludwig Öchslin and his son foundedthe firm Ochs und Junior, which specialises in watchesof rigorous simplicity but also offers ‘open-ended cus-tomisation’. Tim showed us several of their watches,including one with a moon-phase display which willtake 3,478 years to develop an error of one day. As acontrast, he showed us the Terraluna by Lange &Sohne, the lunar display of which takes only 1058 to beout by a day.

As the oddity in his presentation, Tim showed theHYT H2 which has a hydro-mechanical display employ-ing a fluorescein-loaded fluid in a glass tube to indicatethe time. It was not entirely clear what advantage thissystem confers, but it is fascinating. Equally amazingwas the Urwerk EMC (Electro-Magnetic Control). Thisis, in effect, a mechanical watch with an integratedtiming machine so that it can indicate its own degree oferror, which the owner can then correct.

Returning to more conventional horology, Timshowed us the Piaget Altiplano 900P. This watch is only3.63 mm thick, which is achieved by arranging the trainalongside the dial rather than behind it and by usingthe case itself to support the train. For comparison,Tim showed us a thin tourbillon watch of 1986 byAudemars Piguet in which the train was also supportedby the case back.

The final item in Tim’s show was the latest develop-ment in silicon from Ulysse Nardin. This is the AnchorLever, which has no pivot, being supported by ribbonsprings and using the mode of flexure of these toprovide the lever with only two stable positions. Thisobviates the need for a safety or banking componentsand has extremely low inertia. The company’s videoshowed some of the manufacturing process and an ani-mation of the operation of the escapement, which isincorporated into a tourbillon.

It is easy to question the relevance of some of thesewatches, especially as some of them are difficult to tellthe time by, but I think they are a bit like formula 1 carsfrom which the technology migrates to the cars whichwe drive. Price is also an issue. The cheapest watch we

were shown sells for approximately £5,333 and thedearest for about £150k, so it is unlikely that I shall bebuying one.

Tim’s presentation was both enjoyable and informa-tive. If you have the opportunity to see him give it, I rec-ommend that you take that opportunity.

Our next regular meeting will be on 9th February2015, which will be our AGM. Copies of the pro-gramme can be obtained from Colin Reynolds, eitherby post or by email.

Colin Fergusson

Lincolnshire Branch For a change the October branch meeting movedvenue from Lincoln to Upton Hall, where sevenmembers, who had braved the day’s downpour, enjoyeda fascinating, guided tour of some of the MuseumTrust’s collection. Alan Midleton FBHI had very gener-ously given up his time to provide us with what can onlybe described as an ‘evening of enlightenment’. All toooften we visit our HQ and although we can appreciate,on a purely visual level, the clocks and watches ondisplay, what we are unable to do is to have the humanand historical details that go with each piece. Alan’sgenius lies in his intimate knowledge of the collection,delivered with paternal affection and clarity.

Starting in the central hall where the MillenniumClock takes centre stage, it was made clear that thelongcase clocks are not arranged in just any order; theprogression from the single hand lantern clock to theearly examples of more accurate time keeping were setout in linear progression along the wall. The informa-tion about Chinese lacquered cases was surprising,learning as we did that beauty is only skin deep with thebasic carcasses being worked on for many months toproduce the final intricate results.

Having been to Upton a fair few times, the SpeakingClock has become almost taken for granted with its tensecond round of clicks and rotations, but when thehistory of the two clocks is told, it adds so much more totheir rather unflattering appearance that you trulyappreciate the importance of these time dispensinginnovations.

The exhibit that will stay in my mind though isperhaps the least attractive namely the pocket watchthat Scott took to the Antarctic. Not having read thedisplay cards, I found Alan’s unravelling of why acheap, alarm watch should have been taken so far, fas-cinating; it was certainly no chronometer. And it allcomes back to the human, historical colouring that wasapplied to the whole evening. Explanation! If youremain motionless for more than two hours or so insub-zero temperatures then problems with frost biteare likely. So, you need an alarm to wake you up atregular intervals.

Many thanks to Alan Midleton for giving us a deeperappreciation of the heritage of horology that we holdin trust at Upton Hall.

Milton Keynes BranchThe speaker for our October meeting was Ian CooteMBHI who gave us an excellent talk on ‘HorologicalTools’.

Ian, a former teacher, is a member of the Ipswichbranch, conducts a brass band, has been restoring clocksand barometers for the last 20 years, and maintains amost informative website (www.coote.demon. co.uk), sowe were pleased that he could find time to make thejourney to us.

Ian told us that he became a collector of horologicaltools accidentally after buying workshop contents, whichhad been accumulated by three previous generations.Collaboration with a Polish contact led to regulardealing in tools.

The first part of the talk illustrated early tooling andincluded the earliest picture of a lathe (tomb painting300BC), Roman bow lathes, foot operated vertical drillsand a pole lathe.

The talk progressed to horological tools such as turnsand then encompassed the American origins of theclockmakers lathe. The differences between Swiss andEnglish mandrels were discussed together with some‘odd ball’ examples that he had come across.

Further polishing tools such as the swing tool were dis-cussed and examples passed around the audience beforeIan described the development of wheel cutting; fromthe early Swiss saw cutting machine through to modern methods.

A practical demonstration of the rounding up tool wasgiven via microscope and computer projector and thetalk was completed with a discussion about the achieve-ments of Pierre Ingold whose proposal for interchange-able parts was rejected by the trade and a description ofhis tooth polishing technique.

A most interesting evening, extremely well illustratedand enjoyed by all.

Bob Whitehurst

Sussex Branch This month our planned speaker was unable to attendbut we were very lucky to welcome Duncan Greg, whostepped in at short notice. He explained that he is not aregular speaker but had recently been persuaded to givea talk to the Manchester branch so fortunately had histalk prepared. Duncan is entrusted with the care of clocksat Lyme Park, a National Trust property.

The National Trust has over 8000 horological items inits care and four properties which hold exceptional col-lections, Waddesdon Manor, Snows Hill, Anglesey Abbeyand Lyme Park, which itself has 46. The collection wasbequeathed by Major The Honourable Sir Francis LeghKCVO and enhanced by examples from the Glynn Vivianbequest, which became the Gershom ParkingtonCollection.

Duncan gave interesting details on the benefactors andtheir ‘infection’ with the horological bug which all in theBHI also seem to suffer. Many of the clocks are classics ofhorology and most of us can only admire them from a dis-tance, but as Duncan said he has the good fortune to be

able to see the most intricate details while carrying out hisjob of ‘keeping the items in good condition, preventingany material deterioration and conserving their uniqueoriginality for future generations’. He was acutely awareof the heritage of his work as he was following in the foot-steps of the likes of Eric Gent, Jonathan Betts, ViscountMidleton and Sue Ford and we wonder who, in lateryears, will be looking over his shoulder and viewing hisstewardship.

Duncan very kindly gave me his notes so I had thebenefit of all his facts and details and any errors are downto my errors of transcription, but sadly I am unable tobring you the glory of what we were shown with the pic-tures. I will list just a few of the items we were privileged tosee not just from the outside but in intricate detail. Some,like the large wall clock in the servants hall, were made asjust functional timepieces and this item required the useof a large ladder for its weekly winding. Others were itemswe can only dream of such as the Ahasuerus Fromanteelspring clock, the month longcase by Henry Young withfloral marquetry case, the exceptional Grand Sonnerieclock by Christopher Gould, who we learnt he fell onhard times and ‘was reduced to applying for a position asan ale taster’ (sounds good to me!). A musical clock withinterchangeable barrels by Claude Viet, the Wagstafbracket clock with automata, and then we got onto theTompions with superb pictures of the repeating mechanism and mechanical details. A true feast of horo-logical wonder.

In the question and answer time we covered the usualthorny issues of keeping clocks running or just sitting as adusty museum exhibit and also reconversion of past mod-ifications. Here, Duncan is fervently on the same side asMatthew Read from West Dean that any reconversion is fitting modern components and destroying part of the history.

An interesting view was given on the different attitudesof staff at various properties. Some, like those at LymePark, take great interest in their clocks and want to knowhow best to treat them, giving their visiting horologist agood well lit space to work in and making sure they arecomfortable and supplied with coffee, while others sticktheir visitors in a cold broom cupboard and leave them toget on with it!

Duncan was warmly thanked and still talking with members as the room was having to be cleared. Agreat evening.

Gordon Hoare

South London Branch The October meeting was taken up with the traditionalBranch Auction, when we use the Linley Room to book inlots and house them once sold, and the main hall forviewing and selling. A late request to the committee tohelp a current member empty his workshop to facilitate amove to the coast, resulted in a car load of tools and mate-rials being collected the night beforehand by NorvinSimpson and myself. The tools and materials collectedwere sorted immediately prior to the auction by JamesMarten and Alan Westgate into 43 lots. Then the unex-



pected happened and a further 91 lots turned up on thenight resulting in a very full auction. This resulted in theusual mix of various publications, watches, clocks, parts,tools and materials. There did, however, seem to be fewercomplete clocks or watches than previously.

Despite a later start than normal, the full 134 lots weresold, with the exception of one by our auctioneer RoryMcEvoy, in less than two hours, achieving a total in excessof £2,000. Rory used his extensive knowledge to value thelots and the item he withdrew was as a result of it notreceiving a reasonable starting bid. The good news is thatthis was subsequently sold after the auction and in linewith Rory’s valuation. The administration and bookkeeping were performed by the now familiar dynamicduo James Marten and Alan White, in their usual effi-cient fashion. Rory, James and Alan were thanked at theend of the auction for their efforts in running the sale.

Buyers then paid their money and collected their lots,the sellers were then all paid out, and the Hall and LinleyRoom were returned to the ‘as found’ condition beforethe end of the evening, achieved with a great team effortby all the available members of the committee, aided bymany ordinary members. So a huge thank you to all.

As a result the auction was much more successful thanexpected, contributing significantly to Branch fundswhich will be used for the benefit of all branch members.

Grenville Johns

Oxfordshire Branch The speaker at our October meeting was Giles English,one of the founders of The Bremont Watch Companybased in Henley on Thames. The meeting got off to aninauspicious start as Giles’ presentation was on an Applecomputer and there was no suitable connector to our pro-jector. Normally panic sets in at this point but Giles was inno way perturbed. A fascinating story needs no visual aids.Giles and his brother Nick were brought up amidst engi-neering stuff as their father Euan’s workshop containedclocks, models, old cars and old aeroplanes. In March1995, Nick and their father were practising for an airdisplay in a 1942 WWII Harvard aircraft which unfortu-nately crashed, killing their father and seriously injuringNick. Giles was waiting take off clearance when he was toldof the crash. Fortunately, his brother survived notwith-standing the fact that he had broken over 30 bones!

The tragedy did not deter the brothers and in the late1990s they were flying across northern France in their1930s biplane when they had to make an emergencylanding on to a farmer’s field. The farmer’s name wasAntione Bremont. In 2002, the brothers set up Bremontin Biel Bienne, Switzerland. Five years later the firstBremont mechanical watch was launched.

Today Bremont is located in Henley in a purpose builtbarn with retail outlets in London and Hong Kong. Theirwatches are designed, finished and assembled in Henleywith some core components made in Switzerland.Increasingly components are now being made in the UKat Silverstone. They have engineering partnerships withthe Advanced Manufacturing Research Centre andBoeing. They employ 70 people and are training watch-

makers themselves. The plan is to make more and morein the UK.

Setting up a new watch company amid very strong com-petition is not for the feint hearted. However, there is noother high quality English watch company making handfinished watches in any quantity. Bremont has reachedannual production of 8,000 pieces.

In 12 years Bremont has created a very distinct luxurybrand with some very original models all with the COSCSwiss chronometer grade certification. There are modelsmade in partnership with Jaguar, Norton, Martin Baker,Bletchley Park, the Royal Navy, HMS Victory, the USAirforce amongst others. Numerous celebrities feature intheir marketing material. Some of their limited editionprestige models have incorporated some very imaginativeelements, for example, a piece of a Spitfire, fabric fromthe very first aeroplane flown by the Wright Brothers andcopper and oak from HMS Victory.

Bremont represents the top end of English watchmak-ing in the branded luxury sector distinguished not onlyby a commitment to quality but some very original mar-keting. There are many quality watches for buyers tochoose from but Bremont has established a very distinctniche which clearly appeals to individuals wanting amechanical watch rooted in the history of domestic engi-neering tradition.

Richard Snelling gave the vote of thanks for a wonder-ful insight into an amazing journey. The audience wasenthralled.

Course Report

Tool Sharpening Course 6 October 2014Six branch members arrived punctually at the BranchWorkshop to be introduced to our tutor for the day, SidLines MBHI.

Sid is chairman of the Kent Branch of the BHI and aretired Mechanical Engineer.

After a friendly but firm talk on safety we were allhanded a pair of protective safety glasses to be wornduring use of either the bench grinder or drill.

Sid then took us through a very well put-togetherPowerPoint presentation covering the theory of sharp-ening drills, lathe tools including gravers, broaches andreamers, screwdrivers and taps and dies.

‘Don’t be a slave to accuracy’ was the mantra. Sidexplained that in production engineering the angleshave been worked out to give the maximum efficiency,tool life etc, and hence profit for the company.

For our applications it matters little if the angle is115° or 125° – drill will still cut freely and to size.

Sid then showed us a number of guides for sharpen-ing gravers and screwdrivers including some he hadboth designed and made himself.

Now it was our turn! We were handed a piece of highspeed steel to make a lathe cutting tool, grinding oneend suitable for brass and the other for steel.

We were then given a wooden guide Sid had made forus and a diamond stone to practice the four-facetmethod of drill sharpening.

Next we were supplied with 1 mm, 4 mm, and 6 mmdrills which had the tips broken off, and told tosharpen them, and then to prove that we had done itcorrectly by drilling a hole in a piece of 6 mm mild steel.

There was much discussion and banter during theday and even our more experienced members said theyhad learnt a lot.

On departure we were presented with a folder con-taining the information in the initial presentation andall the materials we had used during the day were oursto keep.

This was a really worthwhile day and I would like tothank Sid for the thorough and detailed preparationthat made the day run so smoothly.
