Introducing: The ref. 5270J-001

A new interpretation of a legendary grand complication, with a yellow-gold case.

As the true heir of Patek Philippe’s iconic 1941 classic (Ref. 1518), the Ref. 5270 Perpetual Calendar Chronograph – available since 2018 in a platinum version – now proudly debuts in a yellow-gold case.

It provides an effortlessly elegant outfit for such a timeless watch, combining a concave bezel with slightly flared strap lugs. Aesthetic excellence aside, the watch also displays technical prowess – the Caliber CH 29-535 PS Q is the first chronograph movement with a perpetual calendar developed and crafted entirely by Patek Philippe.

Timeless in design, innovative in its technicality.

As the heir of a grand Patek Philippe classic, the Ref. 5270 Chronograph with a perpetual calendar is now available in yellow gold for the first time – an elegant outfit for this timeless watch with a concave bezel and fluted lugs. The silvery opaline dial is superbly legible. The caliber CH 29-535 PS Q movement combines traditional design with six patented innovations and an extremely slender calendar mechanism.
