I have had a few WW2 USAAC/AF A-11 wrist watches (Elgin and Waltham) but this is my first US Navy wrist watch.
Markings on the case back are:
F.S.S.C. 88-W-800 (Fleet Supply Support Centre/s, Stock/Spec. number).
MFR'S PART NO.2103 (Indicates a Keystone waterproof case)
The Elgin 539 movement has 16 jewels, the s/n is T376649 which dates it's production to 1944, it is running well but will need a service.
I fitted a WW2 era NOS two piece strap, specs. say a one piece strap..... might get one later.
Hope you like this nice addition to my collection.
