Pre-Owned Patek Philippe Grand Complications 5270J

Yellow gold returned to the perpetual calendar chronograph line in 2020 with the 5270J. It was the first such Patek in that metal since the ref. 5970J left production in 2009. Inside the 41mm polished case sits caliber CH 29-535 PS Q, Patek's first fully in-house movement combining a chronograph and perpetual calendar, running a horizontal clutch, column wheel, and a 1.65mm-thin calendar module built from 456 parts across a 55-65 hour manual-wind power reserve. The example available at The 1916 Company has been fully authenticated and carries The 1916 Company's 2-year warranty.
