new to the forum and owning military watches despite being in the services some years back.
Fond this forum and this post while trying to understand the history of CWC and meaning of some of the numbers on the back of the watch; recognised the NSN obviously.
Having trawled through many sale adds, it seems to me that the serial numbers were accumulative and irrespective of which service up to the issue in 95 of the 0555 RM procured G10's. The serial numbers on these watches started from 001 (I assume) and its stayed that way since, with a restart for each year of production.
Have also seen advertised a CWC G10 with no year date and a serial number beginning with C, similar to a description in another post I've read on here. Seller suggested it was from 1999.
The RN appears to have paid for at least 20,000 watches in 1990 going by the serial numbers I've seen, although the company web site indicates this happened in 91? That's a lot of watches and considering I cannot remember anyone having one while I was in, and I worked alongside all the other services at various times.
Oh my first watch is a 0552 from 1990 S/N 56080 (however its a gift for a relative who does a lot of walking).
