Bulova 1973 Accutron Date & Day "F"
This is a watch I received from my grandfather. I do not want to open it up until I know exactly what I am doing. The back of the case is stamped with Bulova, 14KT Gold Filled Case, Water Resistant, J965360, N3. I do not know much about this watch other than I think it is a 1973 Accutron model 221.
