Patek Philippe Grand Complications 5374

Patek Philippe Grand Complications 5374/300P-001 is a 42 mm platinum watch that combines a minute repeater with a perpetual calendar. The case measures 12.28 mm thick and carries a sapphire crystal over a guilloché dial, with the movement visible through the display back. The self-winding calibre R 27 Q provides 38 hours of power reserve and drives the perpetual calendar, which shows the day, date, month and moon phase alongside the chiming complication. Luminous hands allow the time to be read in low light. The watch is set with diamonds throughout. Patek Philippe pairs it with an alligator leather strap closed by a folding clasp in platinum. Given the minute repeater mechanism, the case is not rated for water resistance.
