Here is a Hamilton 21J Pocket Watch that has movement number C319810 written on the inside. It is grade 992B and Model 5 made circa 1951. It's marked ADJ. Temp and 6 Positions, Hamilton Watch Co. USA.  The watch is in excellent condition without scratches or marks and with a clean white dial with a good crystal.  The watch runs and keeps good time.

It's in a case that's marked Hamilton Watch Co. 10K Rolled Gold Plate, Lancaster, PA. There are no marks inside the case that would show it was ever cleaned or repaired so it's reasonable to think that it could use professional cleaning. It comes with a 9" Simmons watch chain and a small gold filled fob.
