The champ dropped a million on an extremely rare Hublot Big Bang Unico Haute Joallierie Collection watch. Hublot made only 10 of these watches . . . but only one with all clear diamonds.

And before you start talking about how he;s BLOWING his money. We're told that the VALUE on this watch is actually around $1.2 MILLION and because of it's rarity, it will likely increase in value over time. So this watch is as much an investment as it is a piece of jewelry.
