Big Pilot's Watch Perpetual Calendar ProSet Le Petit Prince (Ref. IW329601)

The Big Pilot's Watch Perpetual Calendar ProSet Le Petit Prince (Ref. IW329601) integrates our new forward- and backward-adjustable Perpetual Calendar ProSet into the state-of-the-art IWC 82665 calibre, visible through the sapphire glass case back of the timepiece. This groundbreaking module, entirely based on gears, is protected by five patents. A smart mechanical program adjusts the month lengths according to the intricate rhythm of the Gregorian calendar, via a complex geometry arranged across several functional layers within the program wheel. A gold-plated medallion depicting the Little Prince on his asteroid decorates the rotor of the automatic winding system, while the completely re-engineered Perpetual Calendar ProSet module can also be admired through the sapphire glass case back.
