Tiffany and co. Antique 14k gold watch/gf band

Gorgeous running Tiffany’s antique wind up watch. I just got this piece and it runs beautifully and was just serviced and cleaned. The case is solid 14k with name on back and the band is a gold filled band not original to the watch . An amazing piece with pink copper face. Just beautiful. Crystal has a couple small dings but has been well kept for age. The jeweler I bought it from checked the gold validity and authentication. Mathey-tissot movement. Copper deco model. 50s RARE find
