Preliminarily I'd call this a 1941 Lincoln
The case is 14 K rolled gold plate bezel with a stainless back. Marked Bulova New York. The movement is a 17 jewel, 7AP consistent with others in the database and the ad.
I bought this thinking it was a minuteman. But it's got seams in the case that aren't in the minuteman. It certainly looks like the Lincoln ad to me and like the others in the database. Nice coloring.
