Grand Complications – Perpetual Calendar

The Patek Philippe Grand Complication Ref. 5271P-001 is a definitive statement piece for serious collectors and connoisseurs of luxury Swiss watches. This highly coveted timepiece combines Patek Philippe’s legendary perpetual calendar and manual-wind chronograph complications, wrapped in a platinum case of unmatched elegance. The 41mm platinum case is set with 58 baguette-cut diamonds (approx. 4.8 carats) on the bezel and lugs, elevating the already prestigious Grand Complication line to an even more exclusive level. The black lacquered dial features applied diamond hour markers, white-printed scales, and leaf-shaped hands—delivering a rich contrast and exceptional legibility. Powered by the in-house Caliber CH 29‑535 PS Q, this model offers a column-wheel chronograph, moon-phase display, and a fully integrated perpetual calendar accurate until 2100. The watch displays day and month in twin apertures at 12 o’clock, date and moon phase at 6 o’clock, and leap year and day/night indicators at 3 and 9 o’clock respectively. Paired with a hand-stitched black alligator leather strap and a platinum fold-over clasp adorned with diamonds, the 5271P delivers both performance and opulence. A sapphire crystal caseback reveals the exquisite finishing of the movement—a hallmark of Patek Philippe’s watchmaking artistry.
