Four-digit year display
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. The ingenious mechanical programme will not require any manual correction until 2100 when the leap year due will be omitted based on an exemption rule in the Gregorian calendar. Another distinguishing feature is the four-digit year display. An additional century slider is included within the case, enabling this timepiece to show the year until 2499. With all its displays perfectly synchronised, the calendar can be set easily via a single crown, offering a degree of user-friendliness that is unparalleled in the domain of mechanical calendars.
The IWC-manufactured 52615 calibre drives the calendar module using a single nightly switching impulse. The automatic movement comprises 386 components and was engineered with a focus on maximum precision and quality. The Pellaton automatic winding system builds up a power reserve of seven days in two barrels. Parts of the winding mechanism that are subject to high stresses are made of virtually wear-free ceramic. The decorated movement is visible through a glass back. The Big Pilot’s Watch Perpetual Calendar is available from 7th April 2021 through IWC boutiques, authorised retail partners or online at IWC.com. The timepiece can be registered under the My IWC care program and thus benefits from a 6-year extension to the standard 2-year International Limited Warranty.
