As Calibre11 already said, nice, genuine watch, offered by a long-standing reputable seller that I did business with in the past, no problems with the items I bought at all and exactly as described.
The list to look for if a watch is fake or real is too long to list, you will get to know all the details of a watch over time from experience, not something that you can learn quickly.
But just to name a few, look for the logo's, inscriptions, model numbers etc. and compare it to others that you can find on Google images or better: check the Knowledge centre section on the Calibre11.com main site if a watch is in a catalogue for instance, which will be a great help if you are in doubt of authenticity.
Succes!
While some are obvious, some are not so, and it doesn't help that TAG are not above making little known 'special editions' of things which may appear to be fake. I've seen things in TAG boutiques that I would run a mile from online...
No way, which watch? (Just curious).
But you are correct, special editions needs experience from a trained eye and knowing all the documentation and info that you can get, in my opinion.
Nothing particular, but TAG do seem to make special editions that you never even get to know about and that don't appear in their catalogues, it's extremely unhelpful when trying to decide if things are fake or not. Like that Space-X watch with the black face, we know it's fake but that's just the sort of thing TAG might have done and not told anyone!
Collectors rejoice! Here's a one of a kind opportunity.

Despite the attempt at a 'get out' in the description, this slightly bizarre, just look at the date!
