Antique Elgin Pocket Watch Hunting Case Grade 216 (Model 2) Serial 8616764 Estimated Production Year: 1900 Runs Good. I have wound this daily for the last 10 days and it’s keeping good time. About the gold content on this fine watch. The thickness of the gold is far more than ordinary gold filled. From what knowledgable watchmakers have told me the outer cases were made of solid gold with a base metal center, so there is more than doubt quite a bit of gold even if you just decided to scrap the case (which would be sad). This watch was serviced about 3 years ago. The movement is stamped: 8616764 15 Jewels Elgin Natl. Inside the movement lid (dust cover) it says Guaranteed 20 Years J. Inside the back lid reads: Keystone Watch Case 2637183. Stamped inside the cover is 2637183. The crystal is clear and the enameled dial is clean except a pale green line between the 3 and 4. It doesn’t present itself as a crack, but I want to be up front about everything. The case is 42mm wide or about 1.5 inches. Has a monogram shield on the front but no engraving. Weighs 2.2 ounces or 62.2 grams. Suitable for both men or women.
