I've been checking through eBay and I've noticed that a lot of Elgin watches are quite cheap. Can anyone explain why? I've found this 643 Shockmaster and the seller said it's been recently serviced. It's only $140 which seems quite low. I don't think the crown is original but everything else seems legit. Case is highly polished but that really doesn't bother me. Caseback is signed too. Does anyone have any opinions on it? Thank you!
