My fathers watch, now mine. Runs ok and self winds. The hands have rust, and some of the rust particles are scattered on the face.
I searched a long time till I found a picture of the watch that shooter144 recently posted here ID-ing his watch as a 1957 Surfmaster. The differences are this one is 23J, and it has a full sweep second hand. In the discussion about shooter114s watch it was mentioned that there is a crystal listed for a Surfmaster-A model, so perhaps that is what I have?
My watch was held together the same as shooters, with four press pins so I removed those and seperated the case from its gold frame, the whole unit pressing along with the crystal out the back.
The watch face is signed "Bulova", "23 jewels" and "Selfwinding". The back is stamped with "patent pending, L7, C271662". Then the four thin beveled edges of the back are stamped with "BULOVA, *waterproof* Anti-magnetic, Stainless Steel back Shock-resistant, Self Winding. The crown is also signed "Bulova".
