Large Pilot's Watch Perpetual Calendar

In fact, no complication has appeared more frequently on the dials of watches in this collection. Developed in the 1980s by former IWC chief watchmaker Kurt Klaus, the oversized dial lends itself particularly well to the numerous displays required for this mechanism, making it easy to read the calendar information. The Big Pilot's Watch Perpetual Calendar has a stainless steel case, a blue dial and rhodium-plated hands with a blue calfskin strap. The perpetual calendar, which automatically recognizes the length of the individual months and leap years, does not require any manual adjustment until the year 2100. Consisting of around 80 individual components, the calendar module is powered by a single night-time switching impulse from the IWC-manufactured calibre 52615. The components of the Pellaton winding system, which is subjected to the greatest stresses, are made of virtually wear-resistant ceramic. The two barrels have a power reserve of seven days when fully wound. The finely decorated manufacture movement is visible through the sapphire crystal case back.
