Detailed features & specifications
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.
The highly efficient winding system is a refined version of the 50000-calibre family with a bidirectional Pellaton pawl-winding system. Two barrels provide an impressive 7 days’ power reserve. The winding pawls and the automatic wheel are made of black ceramic while the rotor bearing is made of white ceramic.
These extremely hard high-tech materials make the automatic winding system practically wear-free. The indexless balance with a frequency of 4 hertz (28,800 beats per hour) and the Breguet spring guarantee maximum precision. The design and finish of the movement was also considerably enhanced. The proportions of the rotor and the inset “Probus Scafusia” gold medallion are noticeably slimmer.
