I have a watch that I need a little help on identifying the age and movement. It is a gruen guild 17j. Looks like from the 20's or 30's. Someone said a 705 but I can't see it. Pictures are old. I have replaced the crown and crystal and the watch runs like a champ and is quite beautifull. the new crystal really improved the dial. The old one was green.
I never saw "GRUEN GUILD" on the dial before. 1 problem that you can't see is that there is a small scratch above the hour/minute hand post on the dial. I'd hate to refinish, any sufggestions? The scratch is small, but I know it's there. It goes to bare metal.
