Vintage Gold-tone Pendant Watch Inside says CWCCO Trademark Crescent 2350380, there also seems to be something etched on that same surface but I can't make it out. The movement says 17978786 Elgin USA 15 Jewels. I wound it and it seems to be keeping time without a problem. It is in excellent condition and has an open face. The gold tone chain is approx 26" in length.
