IWC Portuguese Perpetual Calendar

For the Portuguese Perpetual Calendar IWC developed a countdown display that can be used to read off the exact number of days remaining until the next full moon, a phenomenon that has been steeped in mystery and legend since time immemorial. Many people believe it has an influence on them, while in many cultures special festivals are celebrated on nights with a full moon. It is in any case undisputed that the moon and its gravitational pull determine the ebb and flow of the tides and thus have an influence on the earth and our lives. The moon in the hemisphere lunar display on the Portuguese Perpetual Calendar measures just 5 millimeters in diameter – about 700 million times less than in reality. Nevertheless, its representation of the course of the moon deviates by just 12 seconds from the actual time taken in each lunar period. The phases of the moon are displayed for both the northern and southern hemispheres.
