Patek Philippe Grand Complications 6104

Patek Philippe's Grand Complications 6104/11P-010 is a Celestial model with a 44 mm platinum case set with baguette-cut sapphires. The case measures 11.33 mm thick, sits under a sapphire crystal, and shows the movement through a sapphire display back. The blue dial maps the night sky over the northern hemisphere and tracks the moon's phase and orbit, alongside a date shown by hand. A brilliant-cut diamond is set at six o'clock, part of 60 baguette-cut sapphires across the case and clasp. Self-winding calibre 240 LU CL C, fitted with a 22K gold mini-rotor, gives 38 hours of power reserve. The navy blue alligator leather strap closes with a sapphire-set platinum folding clasp. The case is water resistant to 30 metres.
