Alright guys. The pics actually aren't that bad but I simply screenshotted them.
I know this whole thing sounds very odd, but since my payment is completely safe until I tell the system that everything is fine with the watch, I just bought took the step and bought it. The worst that can happen to me is that I receive nothing and then I will always get my money back.
When I get the watch I will take it straight to my nearby AD and let them authenticate it. Only then I will tell the system to send him my money. In my opinion I am completely safe this way.
I will let you know how it goes
