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. The
elegant timepiece leaves virtually no wish unfulfilled. It is equipped
with features such as a perpetual calendar, a window showing the year in
four digits and a 7-day automatic movement with Pellaton winding. The
four subdials on the silver-plated dial display the phase of the moon,
the date, month and day, the power reserve and the small seconds. 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 5N gold watch has an arched-edge front glass and comes with
a dark brown alligator leather strap.
