Not exactly a connoiseur..
lol...Anyone who knows Rolex will know it´s a fake, and anyone who doesn´t, will presume it´s a fake.
So, you don´t have where to run....
The contact parts of the watch really doesn´t matter that much, ´cause the gold wears not only where the watch meats the skin, but in some places outside in the middle too.
So, the same care that you would have to have with a full gold model, you will have to have with this TT one. Washing it everytime you take it out of the box, and even if you don´t, you need to wash it occasionally.
The only difference, is that the full gold model have a GEN counterpart, and the TT is a fantasy at all. =)
