Introducing the reinvention of the Big Pilot Perpetual Calendar.

Introducing the reinvention of the Big Pilot Perpetual Calendar.

No other complication has taken centre stage on the Big Pilot’s large dial as often as the perpetual calendar. Developed in the 1980s by IWC’s former head watchmaker Kurt Klaus, the perpetual calendar automatically recognises different month lengths as well as leap years. Featuring a Pellaton winding system fitted with ceramic components, the IWC-manufactured 52615 calibre is visible through the sapphire glass back.

A legendary watchmaker. A one of a kind engineer.

Watchmaker, engineer and artisan. Kurt Klaus developed and revolutionized the mechanics of the perpetual calendar in the 1980s with his groundbreaking single crown operating design. Simple to use and remarkably precise, every Big Pilot’s Watch Perpetual Calendar honors his innovation and brings the classic into the future.

Manufakturzentrum

A Space Advanced As The Watches It Makes

The Manufakturzentrum. Twenty-five engineering firms, 70 construction companies, and 100 craftsmen worked for 2 years to make it a reality. Home to more than 400 craftsmen and employees, it is here that movements are made, assembled and researched.

It is the biggest ever investment in IWC’s history and a clear sign of our commitment to the town and people of Schaffhausen, the historic Swiss town that gives “IWC Schaffhausen” its name.
