A new era of for perpetual calendars begins with IWC-ProSet. Redefining the mechanics of time, the Perpetual Calendar ProSet can be seamlessly adjusted forward and, for the first time, backward – making it easier to set and operate than ever before; adjustability through a single crown position. This groundbreaking complication has been completely reengineered in a gear-based design, while retaining the signature IWC layout.
The Big Pilot's Watch Perpetual Calendar ProSet Le Petit Prince in white ceramic is fitted with a matching white rubber strap. In a charming reference to Antoine de Saint-Exupéry’s most famous novel, the rotor features a gold-plated medallion depicting the Little Prince on his asteroid.
