Portugieser Eternal Calendar

Since the dawn of time, mechanical watchmaking has stubbornly strived for the greatest possible precision and overcoming barriers in terms of the most accurate measurement of passing time. The latest work of the watchmakers from Schaffhausen allows for the precise measurement of not only time but also a complete calendar indications. The Portuguese Eternal Calendar has been programmed in such a way that it is fully mechanically able to indicate the exact date and its derivatives up to the year 3999. If that was not enough, the moon phases – for the northern and southern hemispheres respectively – will not record a deviation of one day until 45 million years later. These are absolute records, and IWC has managed to wrap everything in the elegant style of a classic Portugieser.
