IWC Schaffhausen has launched the Big Pilot’s Watch Perpetual Calendar at the digital Watches & Wonders exhibition. The timepiece with a stainless steel case and a blue dial continues the long-standing tradition of perpetual calendar watches in the Big Pilot’s collection. Developed in the 1980s by Kurt Klaus, IWC’s legendary perpetual calendar automatically recognises different month lengths and leap years. Featuring a Pellaton winding system fitted with ceramic components, the IWC-manufactured 52615 calibre is visible through the sapphire glass back.
No other complication has taken centre stage on the IWC Big Pilot’s large dial as often as the perpetual calendar. Since the first Big Pilot’s Watch Perpetual Calendar was released in 2006 in a limited edition of 25 pieces in platinum, no less than 37 versions of the iconic Big Pilot’s design with a perpetual calendar have been issued.
With the IWC Big Pilot’s Watch Perpetual Calendar (Ref. IW503605), the legendary complication marks its return to the classic collection. The timepiece features a stainless steel case, a blue dial and rhodium-plated hands. The date display and power reserve are located at 3 o’clock, the month display at 6 o’clock. The weekday display and the small seconds share the subdial at 9 o’clock. The double moon phase display at 12 o’clock correctly depicts the moon phase for the Northern and Southern Hemispheres and only needs to be adjusted by one day after 577.5 years.
The perpetual calendar is exceptionally user-friendly
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.
