Ok, a bit more info on this movement. Designed by Louis Müller and marketed in watches by Louis Müller & Cie, Bulova used this movt briefly in the 'Champ' model. Further digging reveals that another name for this company is Fabrique d'Horlogerie La Champagne.

They were also well known for the 'Wig Wag' automatic watch movt. 

Dates for the patent appear to be early 30's and Bulova examples date to 1936. (Square stamp) This movement had a movable stud carrier (rare for the time) and Breguet overcoil. 

Other names used by Müller are Dido, Mars, Aster, and Champ. I have said elsewhere that this was based on the FHF 29, but the keyless works are very different, so I now think this is incorrect.
