I believe this is a 1940 Stamford, but it has a few slight differences compared to the two already on the site. Crystal is not raised, there is an extra "Bulova" stamp on the back cover, the sweeping second hand at the 12 and 6 position is a triangle, crown is flat instead of slightly domed.
Quite possibly a re-dial.
The serial # would indicate this is a 1936 or 1946. Do you have a photo of the movement?

I can get back to you in a few days, how are you determining that off the serial #?

Yes the first number in the case serial # indicates the year in the decade. However the decade isn’t indicated. We determine the decade by the model and advertisements. There is a 1940 and 1943 Stamford in the DB so without doing some research it might be a 1936 or 1946. The date stamp on the movement might give us some insight. The years this model was advertised might help as well.

Interesting, thank you! I'll have to try and open the case then. I might bring it to someone to do it for me since I don't want to damage it, so I'll try to reply ASAP.
Looking through the advertisements it matches three of the pictures quite well as a 1946 Arnold, however looks quite different from the 1946 Arnold already in the database. I guess the best way to tell will be to crack open the case. Will update within a week.
The Bulova Arnold case lugs are part of the case side curves. The lugs on your watch seems to be off-set from the sides.
Finding what I think is possible match for a 1946 Bulova Officer. Could be totally off, but looks similar to watch show in this advert.
Here's another better view of the 1945/46 Bulova Officer.
1946 ad for the Baldwin; looks like a match, down to the triangular marks in the second hand track.

I lean toward the Baldwin ID, good ad find Ken
