If he believed it was real, wouldnt Rolex have sent him a letter stating "You bought a fake. We aint fixin' it." When he sent it in to pay 1300 dollars and have the dial replaced?
Also, to really pass off your reps as gens you have to have really good fakes, and make it believable. Im in a very high income bracket, so noone questions my one rolex and one graham.
Also, another reason to own reps instead of gens.... every week SOMETHING happens to my tt submariner, wacking my wrist against a table, scraping it on a wall, hitting the rim of a drum with it, whatever. If I had put that many scratches and scuffs onto a real one... I would be on the floor hyperventilating.
