A question for the eagle eyed Pro's out there.

I have been looking on ebay for an affordable Rado and this particular seller 'vintagetimewatches' has a few Rado watches for sale and interestingly they all seem to have patina on the hands and faces.
This made me suspicious because they almost look as if they have been 'roughed up' a bit to seem more authentic....or am i now so paranoid about being caught with my pants down that I dont trust anything i see out there?

What do the enlightened among you think?
