IWC watchmaker assembles the Big Pilot's Watch Perpetual Calendar ProSet Le PetitPrince

Rethinking perpetual time. IWC watchmaker Thomas Zimmermann brings the Big Pilot's Watch Perpetual Calendar ProSet® (Ref. IW329601) to life - one microscopic component at a time. Beneath its deep blue dial lies a completely reimagined perpetual calendar, engineered to move effortlessly forward and backward with a single crown. No pushers, no fuss - just pure mechanical logic. As Thomas assembles the calibre 82665, you get a front-row seat to a system built entirely on gears, layered program wheels, and flexible mechanical "fingers" that extend and retract to handle month lengths and leap years. Turn the watch over, and more ingenuity appears: the Pellaton winding system, ceramic components built to resist wear, and a gold medallion rotor featuring the Little Prince drifting through space. Precision meets poetry - assembled by hand. Ref. IW329601 #IWCwatches #IWCpilot #WatchesAndWonders2026
