IWC Big Pilot's Watch Perpetual Calendar automatic green dial caoutchouc bracelet 46 mm

The Big Pilot elevated by a perpetual calendar

The Big Pilot's Watch Perpetual Calendar is one of IWC Schaffhausen's most iconic creations. Inspired by the manufacture's historic observation watches, it combines the unmistakable design of the Big Pilot—exceptional legibility, the oversized conical crown and commanding wrist presence—with Kurt Klaus's celebrated perpetual calendar. Fully synchronised, this ingenious complication automatically recognises the different lengths of the months and leap years, requiring virtually no correction until 2100, provided the watch remains running.

A refined green dial with exceptional clarity

This reference stands out with its elegant green dial, which beautifully showcases the perpetual calendar displays. The day, date, month, leap year and moon phase indications are perfectly integrated while preserving the outstanding readability that defines IWC pilot's watches. The 46.5 mm stainless steel case is paired with a green rubber strap featuring a textile inlay, creating a contemporary aesthetic while ensuring excellent wearing comfort. The EasX-CHANGE® system allows the strap to be changed quickly and without tools.

The in-house calibre 52616

Visible through the sapphire case back, the IWC-manufactured calibre 52616 features the renowned Pellaton winding system with highly wear-resistant ceramic components. It delivers an impressive seven-day (168-hour) power reserve, while all perpetual calendar indications are synchronised through a single mechanism and adjusted exclusively via the crown—one of the defining technical achievements of IWC's perpetual calendar.

A contemporary interpretation of an icon

Water-resistant to 100 metres, the Big Pilot's Watch Perpetual Calendar IW503608 perfectly demonstrates IWC Schaffhausen's ability to blend traditional watchmaking with contemporary design. The combination of its green dial, matching rubber strap and sophisticated in-house movement makes it a remarkable timepiece for collectors and enthusiasts of fine watchmaking alike.
