P.Diddy celebrated his 50th birthday (how old do you feel) over the weekend by inviting some of his closest friends to a lavish party at his Los Angeles mansion. JAY-Z was one of the many celebrities in attendance, and he showed up in style wearing a $2.2 million Patek Philippe watch, as pointed out by our favourite watch outlet HODINKEE.

The super luxury Grandmaster Chime ref. 6300G is the second version of the Grandmaster Chime, which follows the original ref. 5175. Only six of the 5175 were produced, as it was included in Patek Philippe’s 175th anniversary celebration. Whereas the 5175 boasts an engraved yellow-gold case, the 6300G opts for a white-gold version with black and white dials. HODINKEE adds that the 6300G retailed for $2.2 million at the time of launch, as the black-dialed 6300G was released in extremely limited number. Pretty impressive, no?
