The Big Pilot’s Watch Perpetual Calendar Spitfire Story

The bronze case, olive green dial and brown calfskin strap lend this complicated Pilot's Watch a unique character. Depending on the use to which it is put, bronze develops a patina in the course of time and darkens in colour, giving the Big Pilot’s Watch Perpetual Calendar Spitfire its own unmistakable character. 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.

Calibre Family 52000

The twin barrels are the trademark feature of the 52000-calibre family. They supply the watches with sufficient energy for a 7-day power reserve and drive energy-sapping complications like the annual calendar and perpetual calendar.

Perpetual calendar

The perpetual calendar is one of the most fascinating haute horlogerie complications: It is mechanically programmed for 577 years.
