Patek Philippe made the first serially produced perpetual calendar chronograph wristwatch, reference 1518, in 1941, and the combination has been a pillar of its Grand Complications ever since. Reference 5271 is the gem-set member of the family: a platinum case whose bezel and lugs are lined with baguette-cut rubies.

This Patek Philippe Chronograph Perpetual Calendar wears a 41mm platinum case set with baguette-cut rubies and a red gradient dial. Calibre CH 29-535 PS Q inside, on a black alligator strap.

Fun fact: calibre CH 29-535 PS is Patek's own manually wound chronograph movement, introduced in 2009; PS stands for petite seconde, the small seconds subdial, and Q for the perpetual calendar, quantième perpétuel.

The collection

Perpetual Calendar

The calendar that needs no correction until 2100, in series production since 1941

Patek Philippe built the first perpetual calendar wristwatch in 1925, on a movement made in 1898 for a pendant watch, and brought the complication into series production in 1941 with the reference 1518 perpetual calendar chronograph. The mechanism carries the long and short months and the leap year cycle, and Patek states that it needs no correction until 2100. One layout recurs across the family, with day and month in apertures below 12 and the date read by a hand around a moon phase at 6, while other references set the calendar out in subdials read by hands, run it in a single line across the dial, or sweep the date on a retrograde hand. They sit under Grand Complications in the catalogue, in round gold and platinum cases.

Sizes in the family

39 to 41.3 mm on current references, earlier pieces smaller

Who it suits

For the buyer who wants the calendar to look after itself, and will keep the watch running so it never needs resetting.
