IWC Portugieser Perpetual Calendar

IWC's classic Portugieser Perpetual Calendar "Double Moon" is delivered here in White Gold with deep blue dial. The moon phase shows corectly for both Northern and Southern hemispheres. Famoulsy designed by IWC's own Kurt Klaus, all of the various features are ingeniously adjusted by the single crown - no pesky pushers in siught - and correct for over a century!

The moon phase display on the Portugieser Perpetual Calendar diverges by just 1 day in 577.5 years from the actual phase of the moon. In the model with the double moon display, the moon phase and its mirror image show the state of the moon in both the northern and southern hemispheres.

The double moon model comes with the railway-track-style chapter ring typical of the Portugieser, while the designers have transformed the entire moon phase display into a star-studded night sky, so that the moon and stars appear to hover in infinite space. The elegant timepiece leaves virtually no wish unfulfilled: perpetual calendar, window showing the year in four digits, 7-day automatic movement with Pellaton winding and a power reserve display.
