Precision engineering for an eternity

For the first time, IWC presents the perpetual calendar with a high quality in-house movement from the 82000-calibre family

 

No complication epitomizes IWC’s engineering approach quite so manifestly as the perpetual calendar developed in the 1980s by Kurt Klaus. Its mechanical programme automatically recognizes the different lengths of the months and adds a leap day at the end of February every four years. All the displays are perfectly synchronized with each other and can be set simply via the crown.

In the Portugieser Perpetual Calendar 42, IWC has for the first time integrated the iconic complication in an in-house movement from the 82000-calibre family. The IWC-manufactured 82650 calibre’s Pellaton winding system, which is fitted with ceramic components, builds up a power reserve of 60 hours. The displays for the date, month, day of the week, moon phase and leap year are shown in three subdials at “3 o’clock”, “6 o’clock” and “9 o’clock”. The watch, which has a 42-millimetre diameter, is for the first time available in stainless steel and 18-carat 5N gold.
