Bulova 1928 Senator
I've searched the data base and the closest I can come is in the second page of the adverts' slide #10 but I can't make it out well enough to tell. It has a hinged case that say's Pat. Jan. 11 1927, Bulova 14K Gold Filled, New York. Case measures 26.75mmx26.75mm. The 9AT movement has a dust cover.
