I think my watch is similar to this "senator":

Do you think there was adverts for every models and variations of a model in that period?
It is possible that it was an unknown model never advertised?
I agree, your watch is the same as the other earlier Senators in the db.
I think there are quite a few unknown models around that have no matching ads, and many we have not even seen an example of.
One such is a 1930's self-winding Bulova. I have been waiting for pictures, and hope to get some soon.
Meanwhile, I would be happy with Senator for your watch's ID Tony.

That would be a rare bird indeed. It would have to be a bumper, probably an ebauche made by AS?

Rob, I watched a Webinar last week by Adam Harris, guest curator at the NAWCC museum. It was about the history of automatics up until 1940's, and featured one of these Bulovas but the photo did not appear onscreen for me. He is also negotiating buying one other Bulova 1930's auto for his collection, and has promised to email me photos if he can get the piece.
Here is a link to view the Webinar.
