That's the thing...they had to have taken it in as a pawn or bought it from someone. So they know that it is not real or are real dumb...sounds super shady and I would not buy anything from that shop!The biggest thing is, the store won't guarantee it as real/original.
That's not good.
The one store I go to, that buys watches, will give you a certificate of authenticity for any watch they sell.
Do they know if it is stolen? Probably not...
