Patek Philippe has made perpetual calendars since 1925, watches that will not need a correction until 2100. They are the house’s signature complication and the backbone of its auction record.

This 2021 Patek Philippe Perpetual Calendar pairs a 37mm 18k rose gold case with a silver face.

Fun fact: A perpetual calendar knows the length of every month and the leap year cycle, so it needs no correction until 2100. Patek has made one since 1925 and still assembles the module by hand on a movement it built for the purpose.

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.
