IN-DEPTH: A Glimpse at Eternity with IWC's Secular Calendar, the new Portugieser Eternal Calendar

@IWC #iwcwatches #watchesandwonders #watchesandwonders2024 #monochromewatches #secularcalendar #secularperpetualcalendar Eternity is within reach with IWC’s first secular perpetual calendar, which won’t need adjusting until 3999, and a moon phase indicator that will remain accurate for 45 million years! IWC’s Portugieser Eternal Calendar is the undisputed calendar masterpiece of the Schaffhausen-based brand for Watches and Wonders 2024. A colossal technical milestone, the Eternal Calendar marks the brand’s first secular perpetual calendar. Unlike a perpetual calendar that will need a correction in 2100, the Eternal Calendar is fitted with a 400-year gear that overrides the Gregorian calendar’s complex leap year rule exceptions and skips three leap years over four centuries. In short, it will not need to be adjusted until 3999! Combined with a hyper-precision moon phase display that will deviate from the Moon’s orbit by one day in 45 million years, this Eternal Calendar in a platinum Portugieser case is a tour de force. 2024, all rights reserved to MONOCHROME Watches For more about horology, check https://monochrome-watches.com​​​​​​​ for reviews, news, collector's insights, and more.
