The Type A-11 was not so much a specific watch model but a production standard used by a number of watch companies (Elgin, Bulova and Waltham), with numerous case and minor dial/hands variations (there were even silver-cased watches, as nickel was considered a metal more critical for the war effort!), though some design aspects were largely universal: Black dial; white hands; a hand-wound hacking movement with center second hand, hour numbers from 1 to 12; a second scale with smaller minute/second numbers in increments of 10 on the outside edge of the dial; and same-type minute and hour hands.
This Bulova version of the A-11: this was the watch that was issued by the British as the Mark VIII, with an A. Schild SA Cal. 1238 movement (10.5'''), which while basically a Swiss movement was actually built in the US by Bulova as the cal. 10AKCSH, which also resulted in the lack of "Swiss Made" on the dial. The name can be parsed so: cal. 10AK, CS = center sweep, H=hack.
