I’ve just bought this hand-winding W10 but haven’t yet received it. The seller stated he’d bought it new in 2004.

I like the style and design and have every intention of keeping and wearing it but can anyone tell me about these watches and what the codes show?

 

I’ve gathered that 6645-99 means 6645 = NATO, and 99 = UK.

523-8290 is, I think, the NATO supply number.

I’m not sure what 466 is.

An old thread on another (Googled) forum suggests it may be a movement calibre number

There doesn’t appear to be a year number.

Any input?

 

nice piece! you might try posting these questions over on MWR (wwwbroadarrow.net) as they are very informed about these military style watches.

 

Thanks, I’ll try that

 

6645 is the NATO Group/Class number.

Group 66 is Instruments and Lab Equipment
Class 45 (6645) is Time Measuring Instruments

99 is the Nation Code for the United Kingdom

523-8290 is a non-specific number assigned at the time of "codification" to an item of supply by the owner country's relevant NATO codification bureau.

I won't get into the real nitty gritty of the system, it drove me nuts as a victim of it and it's all for box packers anyway.

The 466 is a serial number to allow the owning agency/unit/squadron etc to track and account for the item.

(amazing how much of this shit I remember after so many years ).

 

That’s brilliant, thanks
Just what I wanted to know.
For entirely understandable reasons, we weren’t issued with anything we might break, steal or kill with in the Army Cadets!

 

These watches were made by CWC and sold through their shop in London. Basically a re-issue powered by a eta 2801. They used to supply to the mod but they moved to seiko and then pulsar.
