Diddy celebrated his 50th birthday 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, HODINKEE points out.

The insanely luxe Grandmaster Chime ref. 6300G is the second version of the Grandmaster Chime, following 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.

Patek Philippe has become a considerably popular wristwear choice for celebrities as of late, specifically among rappers. Drake, for example, recently purchased a $600,000 Patek Philippe Nautilus to match his $150,000 Toronto Raptors championship ring.

It's also worth mentioning that this one-of-a-kind Patek Philippe Grandmaster Chime Ref. 6300A recently sold for a record-breaking $31 million.
