Product Details

The IWC Portugieser Perpetual Calendar is the pinnacle of the Portugieser family. The calendar complication, a first in history showing the 4 year digit display and entirely activated by the crown by developed by legendary watch maker Kurt Klaus. Instantly recognisable in its forward thinking over sized and hugely legible case, the IWC Portugieser Perpetual Calendar is a firm favourite amongst collectors and enthusiasts alike.

Offering a fully perpetual calendar, with day, date, month, year and moonphase functions – the actual calendar is accurate for over a century without any adjustment while the moonphase is accurate for half a millenia. An amazing feat of engineering all done before CAD systems and computers. The perpetual calendar is a vital complication for any proper marque and IWC holds its own.

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 18-carat white gold watch has an arched-edge front glass and comes with a black alligator leather strap.
