Watches with perpetual calendar

Invented in the 18th century, the perpetual calendar is based on the Gregorian calendar, decreed by Pope Gregory XIII in 1582. It automatically accounts for the 28, 30 and 31-day months, as well as the addition of the 29th of February during leap years. Every hundred years, the Gregorian calendar suppresses a leap year, except during century leap years. Thus, given that 2100, 2200 and 2300 are common years, watches equipped with a perpetual calendar must be corrected by one day on the 1st of March. Among the most difficult complications to achieve, the perpetual calendar is a marvel of micromechanics, representing both a technical challenge for a watchmaker and an inexpressible emotion for any lover of beautiful timepieces. Among the numerous Jaeger-LeCoultre watches with perpetual calendars, the Master Eight Days Perpetual is an iconic model. With its remarkable proportions, this watch offers a clear reading of the perpetual calendar, featuring the month, date, day of the week and year, as well as its power reserve and day/night indicator.
