Bulova 1960 His Excellency
I belive this to be a 1960 His Exelency. 10K rolled gold plate case. I found the watch on Ebay, bought it well under going rate. I have not opened it since I don't know how to open a top opening watch. Keeps good time, but should be serviced most likely. Gains about a minute a week. The case is marked M0 on the back.
