The Portugieser Perpetual Calendar Story

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. This timepiece is powered by an IWC-manufactured movement from the 52000-calibre family, featuring a solid red gold rotor and blued screws. The 18-carat white gold watch has a blue dial and arched-edge front glass and comes with a black alligator leather strap.

Calibre Family 52000

The twin barrels are the trademark feature of the 52000-calibre family. They supply the watches with sufficient energy for a 7-day power reserve and drive energy-sapping complications like the annual calendar and perpetual calendar.

Double moon phase

The moon phase and its mirror image show the state of the moon in both the northern and southern hemispheres. This gives owners north and south of the equator a view of the moon phase that corresponds to the way they see it.

Perpetual calendar

The perpetual calendar is one of the most fascinating haute horlogerie complications. Originally developed by former chief designer Kurt Klaus and continuously improved since then, it is mechanically programmed for 577 years.
