Take it to Duncan Jewelers in Athens. They‘ve fixed a Rolex and old school Hamilton for me. Great people.Elgin serial number estimates an 1875 production. My grandfather was given it by his father and I believe his father gave it to him. They moved to Illinois from Germany around 1900 so who knows where he got it from. Unfortunately, it doesn't work. I think it was over wound and the spring broke. I want to have it fixed but I'm unsure of who to take it to. I definitely don't want to risk shipping it to a repair shop.
