sixtiescycles, to be gently, this is what is referred to as a "Swiss Fake" made to look like a Waltham 1883 to fake people out into buying what they think is a decent watch. I would doubt that it has 21 actual jewels. It has been recased based on the extra screw marks. The Cashier cases were made in Canada and were gold filled. It it runs well, you did ok, if it doesn't run, it will be expensive to fix. Before you buy a watch, do some reading and research before you end up like me, before I started reading, with an collection of ho hums that I can't resell for anywhere near what I paid for them so they just languish.
