The watch face says Excellency. I am just not sure which model. It has an L1 on the case back and the movement piece. So I assume it is 1951. The glass is pretty scratched up. Inside of case back is Bulova, Fifth Ave, New York and a very faint signature (I think). The diamonds are not real and there are 2 missing (have photo if you need it).
Movement Serial No.
