52000 calibre family

The IWC-manufactured 52000 calibre family comprises large automatic movements. The highly efficient Pellaton winding system uses movements of the rotor in both directions to build up a power reserve of 168 hours (7 days) in two barrels. Components that are subject to high stresses, such as the automatic wheel and the clicks, are made of virtually wear-free ceramic.

Putting eternity on the wrist.

During his time as head watchmaker at IWC Schaffhausen, Kurt Klaus translated the Gregorian calendar with all its many irregularities into a mechanical program for a wristwatch. His legendary complication was first featured in the Da Vinci Chronograph Perpetual Calendar in 1985 and is still regarded as a milestone in watchmaking.
