search.php?keywords=authenticwatches&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=posts&st=0&ch=300&t=0&submit=SearchAuthenticwatches have been mentioned many times on here (30 pages worth of "mentions" in fact according to the above search link!), but in short, yes they sell genuine watches but they are a grey market dealer. Again, a quick search on the term "grey market dealer" will explain what that means, but basically you will be buying a genuine watch from a non-approved source and without an official Breitling warranty.... and any other type of warranty offered may not be worth the paper it's written on as you have no guarantee that any repairs will be completed with genuine Breitling parts. If you do buy from them it's best to just assume no warranty at all and be prepared to pay Breitling to fix any issues out of your own pocket.
