Eternal Time: 6 Modern Perpetual Calendar Watches

Eternal Time: 6 Modern Perpetual Calendar Watches


In modern watchmaking, a perpetual calendar indicates the date, and corrects automatically for months with less than 31 days, as well as leap years. Unless the movement takes into account century years that are not leap years, a watch with a perpetual calendar will need manual adjusting in 2100, 2200 and 2300 but not in 2400. Usually, a perpetual calendar combines additional complications (a moon-phase, for example). From the WatchTime archives, here are six watches that are (almost) ready for eternity.
