A perpetual calendar is a type of movement that automatically adjusts for varying month lengths and leap years, ensuring that the watch always displays the correct date. Unlike other watches, it doesn’t require manual date adjustments, even during February’s leap year cycle, making it an essential feature for accuracy lovers.

How a Perpetual Calendar Works

Perpetual calendars are driven by complex mechanisms that track the number of days in each month, accounting for both 30- and 31-day months as well as February’s variations. The movement uses a sophisticated series of gears that “know” which months have fewer days and when leap years occur, ensuring continuous accuracy.

2. Mechanical Excellence: The design of perpetual calendars showcases watchmaking expertise and mechanical ingenuity, making these watches a prized possession for collectors.
