The Royal Oak Offshore 26364ST.OO.D003CU.01 is a special watch made for the 2010 Tour Auto race. Only 60 of these limited edition timepieces were created. It's basically the same as the National Classic Tour 2010 watch, except for one cool detail on the back. Instead of just a regular caseback, it has a reference to the race. So if you're a fan of racing and luxury watches, this piece is definitely worth checking out. Plus, with only 60 available, it's a real collector's item.
