Patek Philippe Grand Complications 5270

The Patek Philippe Grand Complications 5270J-001 is a perpetual calendar chronograph in a round 41 mm yellow gold case with a sapphire crystal, part of a design lineage that traces back to a model launched in 1941. The silvery opaline dial displays chronograph functions, moon phase, date, weekday, month, and small seconds. It is powered by the manually wound calibre CH 29-535 PS Q, which incorporates six patented innovations and a slim calendar mechanism, offering 65 hours of power reserve. The case has a water resistance of 30 meters.
