I have a Waltham, antique pocket watch,17 jewls,serial #26527789, Fair condition, how much is it worth?
What you have is a 12 size, 17 jewel gr. 235.
This is a good watch-in fact, I have one that I regularly carry.
These smaller watches are not so much in demand-even the high grade ones(which a gr. 235 is not). The value is in the neighborhood of $50-75 in a gold filled case. If, by some remote chance, it’s in a solid gold case the value would be in the neighborhood of $500 at current gold prices(and assuming 14K gold).
