I would say a 992 or a 992B should be a cornerstone in a PW collection. Hamilton produced the 992 from roughly 1900 to 1940 and the 992B from 1940 to 1969 when they closed their doors.
Iconic, workingman's American RR grade watches and they sold as many as they could produce because they were designed well, durable, easily serviced by qualified WM and always at a modest, middle class price point.
Plentiful now, so finding one in your price range should be easy. $200-$300 should bring an extremely nice example with a double sunk porcelain dial with no damage, and an excellent movement. I always evaluate the screw heads in any pictures to see if a ham-fisted amateur with incorrect tools decided to play WM.
Case material(gold) will increase price accordingly.
If you must have a very nice GF Hamilton Case in the era of your movement(no evidence of being recased), expect to pay a bit more, maybe $50.
And...........if you can be happy with a double sunk porcelain dial with a minor hairline or two and a tired looking GF case, the price will drop to $100-150. and sometimes less.
Over the years, I have bought many because there are variations, etc but this is the PW that my dad's uncle had that I remember crawling up into his lap and watching him wind this cool, giant thing that ticked real loud...Dad eventually received it, then me. It will stay in the family. This watch started it all for me.
