Patek Philippe 5270R, Perpetual Calendar Chronograph, Pink Gold

Apart from the new rose gold case material, everything else has remained the same as the previous 5270 models in white gold. The case is 41 mm in diameter, with flat pushers and a mixture of brushed and polished surfaces. An open caseback reveals the manually wound caliber CH 29-535 PS Q that powers the perpetual calendar (day, month, leap year, and day/night display in apertures, date by hand), 30-minute chronograph with central seconds hand, moon phases, and subsidiary seconds. Caliber CH 29-535 PS Q beats at 4Hz, has 33 jewels and 456 total components, with a 65-hour maximum power reserve.

The dial features applied gold hour indexes, with the exception of 6 o’clock. There is a black printed outer chapter ring with a tachymeter scale, and inside that is a minute scale. Three subsidiary dial indicate the small seconds, date/moon phases and chronograph minutes, respectively at 9, 6 and 3 o’clock.

The Patek Philippe 5270G Perpetual Calendar Chronograph is paired with an alligator strap with square scales, hand-stitched, matte dark brown and a matching rose gold fold-over clasp. Interchangeable full back and sapphire-crystal case back are included. The water-resistance rating is 30 meters.
