The IWC Big Pilot's Watch Annual Calendar reference IW5027-09 is a unique piece made in 2018 to benefit the Antoine de Saint-Exupéry Youth Foundation. It features a white gold case and the trademark brown 'Saint-Exupéry' dial.


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.
