Case Serial No.:
1963 Bulova Craftsman "D" 21J 8AC with a M1 date code, 10K Gold filled bezel & caseback, Silver dial with Gold applied numbers/markers and Gold hands, Leather Crocgrain strap.
The ID is tentative, but nothing else in my newer crystal books lists a square 19.3 x 19.3mm crystal, and the 21J movement/Gold filled caseback is consistent with the Craftsman model watches.
The bezel on this one is quite unique for a early 60's watch.
