I second my dear friend Lilach about "after market parts." A lot of people do not realize the significance of purchasing a Rolex with these parts (diamonds, bezels) added by the local pawn shop guy. Rolex will not fix a watch with aftermarket parts. If that is important to you, you should make sure that all parts are factory. I personally do not sell Rolexes with aftermarket parts, but I have no problem directing anyone to a good dealer that does.
