Patek Philippe Ref. 5212a-001 Calatrava Weekly Calendar

Patek Philippe introduces a new function for calendar watches: The weekly calendar is a semi-integrated mechanism that in addition to the day of the week and the date also displays the week number. Further, the Ref. 5212A-001 Calatrava Weekly Calendar is endowed with a totally new self-winding base caliber. Patek Philippe has developed a broad spectrum of calendar functions, from the simple aperture date to the extremely complex secular perpetual calendar that is preprogrammed into the 28th century. For quite some time, the perpetual calendar has established itself as a genuine specialty of the manufacture. The patented Annual Calendar, launched in 1996, triggered a small revolution as a full calendar that only needs to be corrected once a year on March 1. In 2013, the Ref. 5200 Gondolo “8 Days, Day & Date Indication” was welcomed as a fascinating innovation with its instantaneous day-ofweek and date display. Now, Patek Philippe is taking a step forward by expanding its collection of “useful complications” with the addition of a weekly calendar that displays the current week number. It is a decidedly practical function in a globalized world, even in the smartphone era.
