Big Pilot’s Watch Perpetual Calendar Spitfire

The bronze case, olive green dial and brown calfskin strap lend this complicated Pilot’s Watch a unique character. Over time, the bronze develops an individual patina. With the help of a Pellaton winding system and two barrels, the IWC-manufactured 52615 calibre builds up a power reserve of seven days. The components in the Pellaton winding system exposed to unusually high stresses and strains are made of non-wearing ceramic. The perpetual calendar recognizes the different lengths of the months and leap years automatically and requires no correction until 2100. It can be set simply via the crown. The double moon display shows the moon correctly for both the northern and southern hemispheres and will need to be adjusted by one day only after 577.5 years.
