Just a quick note for anyone thinking of purchasing this watch -
Rolex watches ALWAYS come with a certificate of authenticity, and this certificate is guarded carefully by the owners. Lost certificates can be replaced. If the watch has no certificate then it is fake or stolen.
My understanding is that Rolex also keeps records of every service ever performed by them on a watch and maintains a list of genuine watches reported to them as stolen (and that this list can be accessed by the public to verify that a watch hasn't been reported to Rolex as stolen).
dank's "I don't need to prove it's genuine" approach is just precious. If he's not willing to verify the authenticity and genuine ownership of the Rolex, then you have to wonder about how the coins he's been selling were acquired, too.
