The cost of a timepiece with a built-in calendar system that automatically adjusts for the varying lengths of months, including leap years, represents a significant investment. For example, a highly sought-after model from a prestigious brand might command a premium due to its intricate mechanics and luxurious materials. This sophisticated complication eliminates the need for manual adjustments, except for the secular year change in 2100, 2200, and 2300.
Historically, perpetual calendars have been a hallmark of haute horlogerie, demonstrating a watchmaker’s technical prowess and commitment to precision. The value associated with these complex mechanisms reflects not only the craftsmanship involved but also the enduring appeal of a complication that simplifies timekeeping across generations. This enduring quality often positions such timepieces as valuable assets that can appreciate over time.
