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 5N 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.
