Hi my name is ***** ***** I'll be glad to help.
Do you think you can open up the watch to see the serial number that's on the gears?
Here's a site with some tips on how to open your watch in case you need it:http://www.thewatchguy.com/pages/OPENCASE.html
Also, do you know if your case is gold or gold plated? If you don't know...does it have any marks or words on it?
I hate to hear that and I'm sorry to cause you any trouble. I wouldn't ask you to go through all the trouble if it wasn't necessary. Records were not kept on the cases themselves as many people would swap out cases over time. The serial number from the gears is the best way to get all the important info and the most accurate value. I appreciate you going to the trouble to take it to a jeweler. I hope it's not too much of an inconvenience.
There's no rush. Your question won't go anywhere, so feel free to take your time.
