This one is a puzzle. Casing appears to be Senator, Radio City or Blackout, but black and gray face is one I have never seen in this style casing. It is a perfect match to the crystal opening. 8AM movement appears to be an uncommon one and not currently represented in the database. Recessed opening in case back is round and a perfect match to movement. Movement is double stamped 1940 and 1941. Case is yellow gold plate with a stainless back. Band is a replacement.
Case back is marked with serial number on one end and "Bulova Quality" on the other. No interior case markings besides a multitude of jeweler's marks.
Currently running and appears to keep time.
It appears the Senator became the Radio City in 1942 and then became the Blackout in 1943. For a 1941 case it seems this will be a Senator although this dial is not found in any adverts we have for Senator. I do note however that a 1940 advert shows this dial in an Ambassador next to....wait for it.....a Senator. What are the chances they're interchangeable? (talk about wild speculation)

All kidding aside. Based on the case I would suggest this for a 1941 Bulova Senator and wonder about a dial swap
In reply to It appears the Senator… by Geoff Baker
I actually considered that and honestly don't think this is a dial swap. Note the Ambassador has an obscured "6", Subject watch does not. Different dial.
Senator... I've seen it in this dial design several times. Legit imho.
I'm on the fence but in keeping with what we have previously done and the fact that we know the Senator had multiple variants, I'm good with a Bulova Senator for now.

I am also good with Senator. Great find.
Senator..
Finally, an ad confirming the Senator with Black and Silver dial.
