This Royal Navy issued stopwatch from CWC features the split seconds chronograph movement from Valjoux.  Part number 521-6482.


From the serial number on the case back we can accurately date this watch to being issued in 1976.  You can also see that this was only the 37th watch of this model issued across the entire Royal Navy  in 1976.


A split seconds movement is not easy to produce, requiring extra skill in design and horology to achieve it.  Back in 1999, an IWC Fligerchronograph was $3,995.  The split seconds version, they call the Doppelchronograph, which used the same base mechanism as the regular chronograph was priced at $7,995.  That is as blunt a lesson in how the complex split seconds chronograph requires serious input from the manufacturer.  CWC had the contract to supply the British Military and they used the Valjoux 57 movement, as used by Nero Lemania and Minerva among others.  As well as the split seconds, you have a minute counter at 12 and a constant seconds at 6.  This is all working well and you can see that in the video.  Being a military watch the case is chromed rather than stainless steel, which does have signs of use that you would expect from a military piece.

This watch will be supplied with our basic presentation box and our Certificate of Authenticity.

From 1st September 2021 we will be planting a tree for every watch we sell, working with the International Tree Foundation (Est 1922) to make this business positive on carbon.  By buying anything pre owned you are effectively reusing what already exists, but this takes it further and makes us feel good.
