Please check the serial number on the inner workings (movement) and get back to us. The S# on the case tells little. You have included the number 25521304. If that number is on the workings, then the watch is a 10 size, 15 jewel Lady Waltham in a hunter case (covered front). The watch you describe sounds more like a 12 size, open faced model. Contain your excitement (I know it's hard), organize the clues you have to offer and get back to us. Perhaps then we can help. Regards, Doug S.
