I found this American Waltham pocketwatch at my Aunt's home in upstate New York (she's 92) -- guess it was my great aunt's or uncle's or my grandfather's or ?. 14K case, case #711994, I think it says Dueber inside. Case engraved PSB. Hands are blue. Numbers are Roman. Second dial for seconds not in roman. Serial #3759251. A friend's father is a jeweler and antique collector and offered me $300. It's not worn and looks like it's been in a drawer for the last 100 years. No scratches on face. One tiny dent on back of case. And it runs. I'm not that interested in selling but was wondering what your gut tells you about the offer. Thanks in advance. If I screwed up by starting a new thread, sorry, I didn't quite know what to do, though I read all the rules and understand that anything you say can't be taken to the bank and is just an opinion based on what I'm telling you.
