I received this watch along with a stamp and coin collection from my dad. I found it in an old cigar box with his miscellaneous loose coins. When researching I can't seem to match it exactly as it doesn't have the outer divers ring? I asked my dad if he had ever had it altered and he said he said no. He's pretty confident that he bought it new but couldn't remember if it was the late 60's or 70's? Any information would be great and I'm also looking for the proper way and place to sell it (e.g. not sure if it's more valuable if I have it serviced or leave it as original, and not sure the best place to post for selling?). Also, If I tap the face, the second hand starts ticking again for a little while.
Thank you for listening!!
