The Big Pilot’s Watch Perpetual Calendar ProSet “Le Petit Prince” (Ref. IW339601) represents a striking evolution of one of watchmaking’s most revered complications, combining advanced engineering with the poetic identity of IWC’s “Le Petit Prince” editions. Crafted in a 42.9mm white ceramic case, its deep blue dial with gradient finish evokes the vastness of the night sky, contrasted by luminous rhodium-plated hands and crisp white numerals for exceptional clarity. This model introduces IWC’s groundbreaking ProSet® perpetual calendar system—an entirely gear-based mechanism that allows all calendar indications to be adjusted forwards and backwards via the crown, offering an unprecedented level of ease and intuitiveness in a traditionally complex complication.

Powered by the IWC-manufactured calibre 82665, featuring a Pellaton winding system and a 60-hour power reserve, the watch displays the full Gregorian calendar alongside a highly precise double moon phase accurate to over a millennium. Visible through the sapphire case back, the movement is adorned with a gold-plated rotor medallion depicting the Little Prince on his asteroid—a subtle yet meaningful tribute to imagination and exploration. Paired with a white rubber strap and the EasX-CHANGE® system, this timepiece seamlessly blends technical innovation with distinctive design, offering a bold and contemporary interpretation of the Big Pilot’s legacy.
