In the 1980s, Kurt Klaus, the chief watchmaker of IWC, developed the Big Pilot’s Watch Perpetual Calendar, which not only offered various ways of displaying the perpetual calendar but also made it more effortless to read the calendar information.

Kurt Klaus innovatively designed a single crown adjustment mechanism, entirely changing the mechanical structure of the perpetual calendar. This revolutionary craftsmanship can automatically recognize different month lengths and leap years, ensuring accurate operation that stands the test of time.

The latest release from IWC, the IWC Big Pilot’s Watch Perpetual Calendar, does not require any adjustment until the year 2100. The perpetual calendar automatically recognizes the varying number of days in different months and leap years.

This new model is a new version of the Big Pilot’s Watch Perpetual Calendar with a “Racing Green” dial and with a feature of the brand’s EasX-CHANGE system.

The racing green dial exudes captivating allure, as the sun's rays interplay, casting a pristine and arresting aura. It supports date, week, month, and four-digit year display, along with the waxing and waning of lunar phases in the perpetual calendar of the North and South.

At the 3 o'clock position, there are the date disc and power reserve indicator. The month disc is located at 6 o'clock, and between 7 and 8 o'clock, there is a built-in window displaying the year. The 9 o'clock position features the weekday and small seconds hand, while between 10 and 11 o'clock, a small airplane-shaped indicator marked with S or N indicates the southern or northern hemisphere, respectively. At 12 o'clock, the watch displays the moon phase for both hemispheres.

The watch case is made of stainless steel, with a diameter of 46.2mm and a thickness of 15.4mm. It is crafted using polished and brushed techniques, enhancing its visual texture. It has a water resistance of up to 60 meters. The side features an onion-shaped crown that allows for the simultaneous adjustment of all the perpetual calendar functions.

Powered by the IWC52615 self-winding movement, beating at a frequency of 28,800 vph. The perpetual calendar module, composed of a mere 80 individual components, derives its driving force from a single nightly transition pulse.

Within the Pellaton's winding system are components engineered to endure extraordinary pressures, meticulously crafted from virtually wear-free ceramic materials. Once fully wound, the dual barrel configuration bestows upon it a remarkable power reserve of 7 days.

Through the sapphire crystal exhibition caseback, the intricate components of the movement are revealed, showcasing their exquisite craftsmanship. The oscillating rotor is elegantly embellished with an 18K gold IWC emblem, adding a touch of opulence and sophistication. Paired with a green rubber strap, it further enhances the theme color of racing green.

This new IWC Big Pilot’s Watch Perpetual Calendar“Racing Green” timepiece continues the enduring tradition of the series. Just as the brand emphasizes, each new perpetual calendar wristwatch is a remarkable creation that pays homage to the classics while leading the way into the future. And indeed, this new creation is truly worth savoring and appreciating in all its details.
