How long do perpetual calendars last?
The most sophisticated and complicated calendar type, the perpetual calendar will automatically track the day, date, month and other information for the wearer until the year 2100, taking into account leap years. Perpetual calendars are put through accelerated time simulations to ensure they accurately display the date for centuries to come. This meticulous attention to quality control is a crucial factor in Patek Philippe’s premium pricing, as it ensures that each watch meets the brand’s exacting standards.
