IWC Schaffhausen - Pilot’s Watches

Big Pilot’s Watch Annual Calendar Spitfire

Stainless steel case, 46.2 mm. Made in Schaffhausen, Switzerland. Model IW502702
The annual calendar of the Big Pilot’s Watch Annual Calendar Spitfire shows the month, date and day in three separate windows arranged according to the American date format. 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 slate-coloured dial has two subdials at “3” and “9 o’clock” – one for the power-reserve display and one for the red small seconds hand. 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 and the various decorations on the plates and bridges.
