Patek Philippe Grand Complications 5374

Patek Philippe's Grand Complications 5374G-001 has a white gold case measuring 42 mm across and 12.2 mm thick. The self-winding calibre R 27 Q drives the movement, with a power reserve of 38 to 48 hours. A sapphire crystal sits over the blue Grand Feu enamel dial, which shows a guilloché finish and luminous hands. The watch combines a minute repeater chiming on two cathedral gongs with a perpetual calendar tracking day, date, month and leap year, plus a moon phase display at six o'clock. Weekday is also shown. The case is fitted with a shiny dusk blue alligator leather strap on a white gold folding clasp. Given its complications, Patek Philippe notes the case is humidity- and dust-protected only, not water-resistant.
