Bulova 1943 Military Non-Issue

Please identify. I believe I have a 1940’s Bulova A-11 Hack model watch.  Issued to a family member.  It has I’m assuming a custom dial, since I can’t find any other with the same.  The engraving on the back plate is gone but evidence can be found on the inside due to transfer. Also the Bulova badging is in a different location on the movement then other A-11’s I’ve seen.  Not sure what the case is made of but it’s definitely not steel due to the patina.
