10 PERPETUAL CALENDARS FOR LEAP YEAR

A leap year is a year with one more day, so 366, instead of the usual 365, arbitrarily set at February 29 every 4 years.

The perpetual calendar is a watchmaking complication consisting in displaying on a mechanical watch the day of the month (the calendar), the month and the position of the year in the leap year cycle automatically: the change from the last day of the month to the 1st of the following month does not require any date correction by the wearer, including the 29th of February of a leap year.

Discover this complication through this selection of 10 perpetual calendars from 10 different brands.
