Rockdoc,

Go to http://www.oldwatch.com. They will probably have something listed close to what you have which is an early Waltham pocket watch. You can go into their webb site and date your watch via the serial number. THey also have a 800 number listed. Give them a call and they may be helpful. It can be very difficult to find someone to work on your watch, so I hope it is running.

Regards,

Max
