Patek Philippe Grand Complications Celestial Platinum Watch 6102P-001

As complex as the sky itself, the Patek Philippe Grand Complications ref. 6102P-001 turns the dial into a moving map of the northern hemisphere night sky. Three sapphire crystal discs rotate independently to display the stars, the Milky Way, lunar phases, and the moons orbit in real time, creating the effect of a miniature mechanical planetarium on the wrist. A blue date scale circles the outer edge, tracked by a red crescent-tipped pointer hand.The 44mm platinum case uses hollowed lugs to reduce some of the visual weight, while a small diamond sits discreetly into the case side at 6 oclock.
