The generously proportioned case diameter of 46.2 millimetres, as well as the iconic design in the style of an easy-to-read cockpit instrument, were inspired by the Big Pilot’s Watch Calibre 52 TSC from the 1940s. This version, which is limited to 250 pieces, was explicitly designed to be worn on the right wrist. For this reason, the eye-catching, diamond-shaped crown is situated on the left-hand side of the case. This makes it infinitely more practical to operate, for example, for left-handers. A soft-iron inner case protects the IWC-manufactured 52010 calibre from the detrimental effects of magnetic fields on the watch’s accuracy. The automatic Pellaton winding system is fitted with ceramic components and builds up a seven-day power reserve in two barrels. This Big Pilot’s Watch features a power-reserve display at “9 o’clock” and a small seconds hand at “3 o’clock”.
