1948 Bulova Commander
This one may be difficult to identify with certainty since we have several similar called Watertite and Seabee. However, this one is like new with a tag labeled Commander 183. Reference 183 is also used with the Watertite model, per pricelists. I picked this up several years ago with some other NOS watches. The case is a top loading type, inside stamped Swiss 48, but no case serial number, like we see in similar cases from this era. Dial is a full numeral lume with outer track and red seconds hand; Swiss movement is dated 48; original Bulova signed leather strap.

Agree., We could probably debate back and forth what other models it may be, but here we have the original hang tag, so I think it's fair to say that should trump us discussing what else it could be.
I acknowledge that the hang tag may not be original to the watch, but nothing here suggests that.
