IWC
Portuguese Perpetual Calendar

Ref.: IW503202

In early ‘80s IWC developed a technical process to transpose the Gregorian calendar and its various anomalies into a mechanical wristwatch.

The outcome was the IWC signature perpetual calendar system, launched in 1985, made of just 80 components which indicates the date, day, month, the iconic four-digit year and moon phases.

The caliber automatically knows the different lengths of the months and adds a leap day at the end of February every four years. Furthermore, moon phase indicator is so precise that it deviates from the real phase by just one day after 577.5 years.

The calendar requires just one adjustment in non-leap secular years, such as 2100, 2200, and 2300.

The present iteration, cased in rose gold, features also a dual moon phase indicator that allows to check moon phases  both in the Northern and Southern hemispheres.

It comes with original box and papers.
