IWC watchmaker Thomas Zimmermann builds the Big Pilot Perpetual Calendar ProSet® Le Petit Prince.

Complexity, on command. IWC watchmaker Thomas Zimmermann builds the Big Pilot Perpetual Calendar ProSet® Le Petit Prince piece by piece - revealing more of the inner workings, from the calendar mechanism to its intricate network of gears. At its core, the IWC-ProSet system is a fully synchronized system, automatically tracking month lengths and leap years. Every indication adjusts forward and backward via a single crown - direct, precise, immediate. Powered by the calibre 82665 and finished with the Little Prince rotor, it's a complication rethought for today. Find the full content in the video section of our profile. Ref.
