Preliminary diagnosis wold be 1943 Broadcaseter
The case is 10K yellow gold filled and is marked Bulova Fifth Ave New York on the inside. The movment is a 21 jewel 7AP with a 1943 date code.
It's as I bought it. It runs well. One potential problem is that the face has numbers on it. It looks to me like most of the Broadcasters at this time didn't have them (see the ad). ON th eother hand the subsecond dial looks like it usually has numbers. My watch doesn't.
It actually is a lot cleaner than the pictures make it look. the phones nowadays are so good they exaggerate every flaw. I don't think the lighting helped.
