Is it that simple though ? Like devils advocate here, if you buy a replacement non factory part for your Nissan GTR is it a fake GTR now ?
If the car was still under warranty then you would have invalidated the warranty. Nissan might not tell your car is fake, but Rolex policy is perfectly clear, if all parts on the watch are not 100% genuine, unmodified Rolex parts, then the watch is considered to be a non-authentic Rolex (i.e. counterfeit) and they will refuse to service it or recognise it as a Rolex.
My question simply was "if i bought a dial from a td on the forum would it fit a gen watch?"
And the answer is 'That depends' - is the dial made to the same specifications as a genuine dial ?
