Patek Philippe Grand Complications 6102

Patek Philippe's Grand Complications 6102P-001 is a 44 mm platinum piece from the Celestial family, part of the Grand Complications collection. The case measures 10.58 mm thick and carries a diamond set at 6 o'clock. A self-winding calibre 240 LU CL C drives the watch, with a 22K gold mini-rotor and 38 hours of power reserve. The sapphire crystal covers a blue dial that maps the night sky over the northern hemisphere, with a central hand tracking the date and the moon's orbit and phases shown across the dial. The sapphire caseback reveals the movement's 305 parts. The watch closes on a shiny navy blue alligator leather strap with a platinum folding clasp. Patek Philippe rates the case to 30 metres.
