Big Pilot's Watch Perpetual Calendar

Ref.IW503605

IWC's perpetual calendar has its roots in a revolutionary mechanism developed by the genius watchmaker Kurt Klaus in the 1980s. By making the previously complicated perpetual calendar adjustable simply by turning the crown, it brought about a revolution in the world of mechanical watches. This model, featured in the Big Pilot's series, has earned high praise as a flagship model that symbolizes the history of aviation watches and IWC's advanced technological capabilities.

This model, a Big Pilot's Watch representative of IWC, is equipped with an advanced perpetual calendar mechanism. Its complex mechanism automatically controls the date, day of the week, month, four-digit year, and moon phase, while its practicality is enhanced by intuitive crown adjustment. Equipped with an in-house movement boasting a long seven-day power reserve, this timepiece combines the power of a pilot's watch with the luxury of a complex mechanism.

The deep blue dial features multiple calendar displays in a well-balanced arrangement, maintaining legibility despite its complex mechanism. The large case and onion crown create a powerful, big-pilot look. The beautiful moon phase display, reminiscent of a starry sky, is also impressive, creating a striking finish that combines the functional beauty and luxury of an aviation watch.
