Unfortunately for the genuine buyer fakes are getting better and better, and in recent years TAG Heuer has definitely increased its marketing, they are more popular than ever. And thus the reps become more popular.
Still, ive yet to see a fake that can fool us hopefully we can continue to have a strong reporting community on here!
