The Big Pilot’s Watch Annual Calendar Edition “Antoine de Saint Exupéry” with an 18-carat 5N gold case is a special edition with a unique design that commemorates the author and pilot with the letter “A” for Antoine on the dial, the tobacco-brown colour of the dial and the calfskin strap inspired by his flight suit. This timepiece features an annual calendar, which shows the month, date and day in three separate windows. The advance mechanism automatically takes the length of individual months into account and requires manual correction via the crown once a year at the end of February. The in-house 52850 calibre has two barrels to provide the higher torque required to drive the three display discs of the annual calendar. In addition, when fully wound, the twin barrels supply enough energy for a full 7 days’ power reserve. The sapphire-glass back provides a view of the exquisite movement, the rotor in the shape of a plane and the various decorations on the plates and bridges.
