"Rolex is not a 'real' Rolex if it has been modded. So that means.."
A...What if the Gomer putting 'The Watch' together in 'The Factory' puts a screw (The Original Screw!) in a watch and then scratches the head of the screw while tightening it, removes 'The Screw', discards it, and reaches into a cup of screws and gets another one and installs it. The 'Original Screw!' has been replaced by a 'Screw! Not Original To The Watch' aka 'screw-modification'. By their own rules, "It's a Fake!" before it leaves The Factory.
B...Once the back is opened and the 'Hallowed Swiss Alps Air' escapes, then is replaced by 'foreign air' (aka 'air-modified')...this means "It's a Fake!" from that point on.
C...Same goes for fingerprints...one 'foreign fingerprint' (non swiss relaxy factory) and it has been 'fingerprint-modified'. So...from then on, "It's a Fake!"
D...How about environment...since they are 'Born and Bred' in 'The Swiss Factory!', any change of location renders them 'modified by enviromental forces'. "It's a Fake!" from the second it left the factory.
Therefore...they are All Fakes!
I can live with that.
