IWC Watches

With ProSet®, everything is fully synchronized and controlled via the crown - forward or backward.

Complexity, made usable. IWC's Gianmarco Nava breaks down a perpetual calendar that changes the rules. With ProSet®, everything is fully synchronized and controlled via the crown - forward or backward. No correctors, no sequences. Just a complex system of gears translating the Gregorian calendar into motion. Add a moon phase accurate to 1,040 years, and the result is as precise as it is intuitive. Ref. IW339601 Ref.
