Reference 5270, launched in 2011, is heir to several generations of Patek Philippe perpetual calendar chronographs. The Manufacture reinterprets this timepiece in a model featuring an iconic yet original style. The radiance of platinum — the most precious metal of all yet also the hardest to work with — magnifies the timeless design of the case, with its concave bezel, its elegant two-tier lugs and its correction push-pieces that are satin-brushed on the flanks and polished on top.
The perpetual calendar displays are harmoniously arranged, with the date indicated by a hand and a moon phase at 6 o’clock, as well as a twin day/month aperture at 12 o’clock, complemented by two round apertures for the day/night indication and the leap-year cycle. Caliber CH 29-535 PS Q is distinguished by its traditional architecture, combined with six patented innovations relating to the chronograph, as well as by its exceptionally thin calendar mechanism.
