I'm seeking any information to explain or understand inconsistencies in identifying this watch. It is an automatic Seamaster De Ville that has been passed on to me from my father. My father passed away in June of 1959, so a logical understanding would date this watch prior to that date. Where I'm having confusion is trying to match it to any Seamaster De Ville with all of the same design elements.
I know that Omega produced an automatic Seamaster De Ville in 1959. But any examples I have found show a different style of hands and different design in the crown. I have found similar hands and crown on later models ( which adds to my confusion). I also am having trouble in understanding the lack of a Seamaster logo on the back of the watch. I've noticed that the Hippocampus logo appears on earlier designs of Seamaster watches, and yet is eliminated on certain later models of that watch.
Anyway, I'll post pictures below and ask that any input from members here would be greatly appreciated in helping me understand this watch. The watch was originally bought in New York..
