I've bought an Emporio Armani watch on eBay. I believe it's not original but a fake/replica. Does anyone know how to spot fake AR1400/AR1410 copy watch?

The ability to spot a fake Armani watch
is becoming more difficult by the day; with con artists perfecting the fake
copy of the watch down to the most minute detail.

However, there will
still be differences if you look hard enough. Check out some of the buyers
forums on Ebay - like this one :

In these forums, you will be able to find other Ebay users who will have bought a similar – if not the same watch as yours. There may also be people who can
help you spot the differences between the fake watch and the genuine article.

If the watch does turn out to be a fake then contact Ebay who
will look into the matter for you and may possibly get you a refund.
