Portugieser Eternal Calendar
The Portugieser Eternal Calendar is the first secular perpetual calendar from IWC Schaffhausen and automatically considers the Gregorian calendar’s leap-year exceptions. In addition, this horological marvel also features a moon phase display with a mathematical accuracy of 45 million years.
Portugieser Eternal Calendar | IWC Schaffhausen
IWC’s first secular perpetual calendar automatically takes into account the Gregorian calendar’s complex leap year exceptions by skipping three leap years over a 400-year period. In addition, its moon phase display is so precise that it will – theoretically – only deviate by one day after 45 million years.
