Vegas is great for brand boutiques, not so good for vintage. There are jewelry shows in the winter that attract all the major vintage dealers. Bring lots of cash. You could try the many pawn shops, but don't expect to find any bargains. Happy hunting, gatorcpa
I don't think so pawn shop is the best place for vintage watches. You can buy vintage timepieces from retailers because they can provide you the warranty of that timepiece also which pawn shop doesn't give.
