Follow up to previous Zenith El Primero 'WORKZONE' illuminated images ... this is the watch movement photographed last week using the XV and Elpro c/u lens using daylight ... i.e. window light plus reflectors.

... the watch was supported on an acrylic stand. This El Primero watch dates from the 1990s.  The Zenith Caliber 400 is the 'base caliber' used in the Rolex Caliber 4030 ... as used in the Rolex Zenith Daytona 16520 series ... a much modified movement with Rolex parts and 'detuned' from Zenith's 36000 vph to Rolex's 28800 vph. Rolex's version was initially unreliable and required further modification to improve reliability.

Watch discovered in a damaged state in a Peterborough pawnbroker 13 years ago and subsequently restored by Mark Wiles F.B.H.I. (Antique & Modern, East Barnet Village, N. London). Mark initially thought  the watch was Georgian as the movement is of a Georgian style and quality.  In the early to mid 19th C., Coventry UK had a thriving watchmaking / clock making industry but in the latter half of the 19th Century went downhill when cheaper clocks and watches from the USA and Switzerland flooded the market. In an effort to compete the Coventry Co-operative Watch Manufacturing Society was formed in 1876 … it introduced economies of scale whilst maintaining quality watch design. This 1893 key wound fusee movement pocket watch  is a very fine example of a CCWMS timepiece and one of the very few surviving examples to have the CCWMS trade mark engraved on the balance cock. The Assay Office hall mark is indistinct but the K date hall mark font likely identifies as being Chester Assay Office. I am planning to take an infra red photo of the Assay Office hall mark to see if IR will reveal any detail in the ‘smudged’ stamp.  Cheaper Swiss and USA imports coincided with the growth of the Coventry bicycle, motor cycle and motor car / lorry industries. Watchmakers' skills transferred to the bicycle and motor industries … fusee chain and bicycle / motor cycle chain manufacture are similar apart from ‘scale’. In 2010, Paul Shufflebothom, Chairman of the Coventry Watch Museum advised regarding CCWMS:  

“ Coventry Co-operative Watch Manufacturing Society was set up in 1876 when they registered their trade mark. They worked at 35 Mount Street Chaplefield Coventry until 1900 … then at Stanley Terrace until 1918 when ceased trading. The CCWMS was one of the founding members of the UK Co-operative Union which is still active today.” 

Leica X Vario, Leitz Elpro VIb 4.92 achromatic close-up lens; Lastolite 2ft Cubelite light tent (kitchen window daylight illumination) … Watch supported on acrylic stand. ISO 400, f16, exposures c. 1 second using 2 second self timer … camera on tripod.

Decided to photograph the Coventry watch again ... with a white (ish) polyester background  ... using a Lastolite Cubelite and with custom white balance for kitchen window cloudy daylight ... Difficult trying to kill some of the reflections so took the liberty of using a Leitz paperweight to reflect the Leitz logo into the watch case ... Might enter the pic in a club competition ... to confuse the judge and enable him / her, to let rip ref its 'busy-ness' ... The acrylic supports are very useful for mini studio photo set-ups and can be bought in sets of different sizes ... some are stepped with 2 and  3 levels. Regardless of how the 'exploded' watch was displayed, it was impossible to include both the movement and the dial ... thus set up a small mirror at 30º angle underneath the acrylic stand to reflect the dial ... and held a gold reflector above the set up and waved the reflector back and forth during the long exposure to avoid its texture showing up in the mirror. The watch key both winds the fusee movement, and, when fitted to centre arbor in the middle of the dial,  turns the minute hand (and thus the hour hand). Since posting the previous photo of the watch I've discovered that the basic ebauche frame for th movement was bought in by CCWMS Coventry from the John Wicherley Watch Co. in Prescot, Lancs. UK (who supplied hundreds of UK watchmakers with ebauche frames); CCWMS then finished / refinished the movement using either additional parts made themselves' or outsourced from other Coventry watchmaking specialists .... those parts being the escapement, enamel dial, hands and case ... in this example an 18ct gold case made by Edwin James Walker (E.J.W.) in Coventry. The case was sent to the London Assay office for hallmarking .. hence its K 1885 hallmark date. The whole watch was assembled / finished over a period of several weeks or months.

You should aim to please yourself, Dunk, not the judges, who feel they have failed  if they don't find something to criticise. Your picture is full of interest, and is very pleasing to view. I am glad you used natural light, my preferred source. Well done!
