IWC Portugieser Perpetual Calendar

This watch is in a pristine condition. The 18ct white gold case has been polished and had a rhodium treatment by IWC itself. The beautiful automatic calibre is visible through the sapphire covered case back.

A moon you can rely on, even under cloudy skies: the perpetual calendar’s high-precision moon phase display needs a one-day adjustment every 577.5 years.
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 slate-coloured 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 watch has an arched-edge front glass and comes with a black alligator leather strap.
