1939 Bulova Watertite I believe. Pretty unique two toned case?
Front loader with a two part stem. Nice engraving on the back which I would assume is some sort of military identifier for the first owner?
Ah that was you that outbid me. Congrats. 1939 Bulova Watertight is a good match based on my confirmation of the Watertight box. It seems this came in several versions, stainless, yellow gold and now two tone.
Do we have any adverts?
1941 Charlotte Observer Ad. It does not mention the gold accent bezel ring but it all lines up.

I'm curious about the back engraving.
This watch would look killer if you can get that bezel ring replated.
Nice to see a dial actully match the advert.
1939 Bulova Watertight.
Sweet find plains, 1939 Bulova Water Tight. Interesting that Bulova was advertising watches for servicemen BEFORE we entered the war.
Very nice!
