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.
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.
Driven by the IWC-manufactured 52615 calibre, the Big Pilot’s Watch Perpetual Calendar’s automatic movement is designed for ultimate reliability and precision for today. The Pellaton automatic winding system creates a seven day power reserve, and control through the single crown offers unparalleled ease and simplicity
The elaborately decorated movement is on full display through the sapphire glass back. Every advancement is fully visible and celebrated.
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.
