Quality and Fine Workmanship

Calendar Watches

Patek Philippe thrives in the world of watchmaking complications, and calendars watches are amongst our most distinctive.

Date Display

The simplest expression of a calendar in watchmaking is the date complication, which displays the current date – a number between 1 and 31 – on the watch dial, either via an aperture or a hand. The date advances automatically at midnight each day, and the wearer needs only to manually adjust it at the end of each month with fewer than 31 days, which represents five months a year.

Annual Calendars

The most famous of our “useful complications” is the annual calendar, invented and patented by Patek Philippe. Introduced in 1996, this mechanism provides an ingenious answer to the problem of date display. It indicates the date for months of 30 and 31 days and needs only one correction per year, at the end of February. The annual calendar is also combined with other complications such as moon phases, chronographs or minute repeaters.

Advanced Research

The Advanced Research program is one of the strongest expressions of our tradition of innovation. From 2005 to 2008, the Annual Calendar mechanism was featured in three Patek Philippe Advanced Research timepieces, featuring some ground-breaking new technological innovations in the field of Silinvar®, a revolutionary material impervious to variations of temperatures, lubricant and other parameters.

Perpetual Calendars

The perpetual calendar is a highly coveted watchmaking complication that automatically takes into account monthly variations as well as leap years. Therefore, as long as it keeps running, it won’t require any adjustments for decades. Today, following a long history of continuous innovation to further develop this useful complication, perpetual calendars occupy a place of honor in our current collection.

A Tradition of Innovation

We were the first manufacture to create a wristwatch equipped with a perpetual calendar back in 1925, based on a movement we produced in 1898. This historically significant watch, Ref. 97975, is on display at the Patek Philippe Museum in Geneva.

Centennial Calendars

A centennial calendar addresses the perpetual calendar’s inability to handle centennials non-leap years. On such occurrences (the next one will be in 2100), the movement must be manually adjusted between February 28 and March 1st. The centennial calendar is an extremely rare watchmaking complication and can be found in our Caliber 89, on display at the Patek Philippe Museum.
