The Big Pilot’s Watch Annual Calendar Edition “Le Petit Prince” (Ref. IW502705) features an 18-carat white gold case and a blue dial powered by the IWC-manufactured 52850 calibre. This unique piece has a blued movement and an ornate, hand-painted rotor, adorned with a blue floral pattern, which takes the form of the little prince – from Antoine de Saint-Exupéry’s story “Le Petit Prince” – on an asteroid. The movement is elaborately coated with metal oxides to give it its blue colour, an effect which is achieved using the process of chemical vapour deposition (CVD). “I am delighted that we are able to use the proceeds raised from auctioning this exclusive Pilot’s Watch to support the important work of the Antoine de Saint-Exupéry Youth Foundation again this year,” says Christoph Grainger-Herr, CEO of IWC Schaffhausen.


IWC caliber 52850 Located at “12 o’clock” on the dial, IWC’s annual calendar shows the month, date and day in three separate windows. The mechanism automatically takes into account the differing lengths of individual months. Unlike a perpetual calendar, however, the annual calendar is unable to make allowance for the leap days in February or the leap years. Once a year, then, at the end of February, it requires manual correction. In the case of IWC’s annual calendar, the correction is made simply, via the crown.
