Big Pilot's Watch Perpetual Calendar ProSet
IWC has introduced the Big Pilot's Watch Perpetual Calendar ProSet, featuring a new bidirectional perpetual calendar module called ProSet. This system debuts in a 42mm Big Pilot case, making it the first Big Pilot under 46mm to incorporate a perpetual calendar with a four-digit year display, mirroring the styling of the original 46mm version.

The ProSet perpetual calendar module is a new bidirectional system, distinct from IWC's previous Kurt Klaus perpetual calendar design.
This 42mm ProSet is the first Big Pilot under 46mm to feature a perpetual calendar and retains the iconic four-digit year display.
The movement, caliber 82665, utilizes a single mainspring barrel and incorporates the Pellaton pawl winding system with a ceramic pawl carrier and a free-sprung balance.
The watch is available in 18k pink gold, ceramic, and steel configurations.
Unlike earlier Kurt Klaus modules, the ProSet design is entirely new and does not rely on the classic grand lever and month cam system, instead utilizing a gear-based approach.
