The legendary complication returns to the standard collection with the Big Pilot’s Watch Perpetual Calendar. The timepiece has a stainless steel case, a blue dial and rhodium-plated hands. The indicators for the date and power reserve are at 3 o’clock, the month is displayed at 6 o’clock. The day of the week and small seconds indicators share the subdial at 9 o’clock. The double moon phase display at 12 o’clock correctly shows the moon phase for the northern and southern hemispheres and only needs to be corrected by one day after 577.5 years.
The calendar module is driven by a single nightly switching pulse from IWC’s manufacture calibre 52615. The automatic movement consists of 386 individual parts and was developed with a focus on maximum precision and quality. The automatic Pellaton winding mechanism stores a power reserve of seven days in two barrels. Heavily stressed components of the winding mechanism are made of virtually wear-free zirconium oxide ceramic. The decorated movement is visible through a glass back.
