Over 75 years ago in 1940, IWC unveiled its large 52 T.S.C calibre observer’s watch (Tirette Seconde Centrale) designed for the military. The design and sheer size of the piece inspired the Schaffhausen brand to produce two versions of the Big Pilot’s Heritage Watch. The pair come in a 55 or 48mm sandblasted titanium case fuelled by a manual wind movement: the XXL model has a 98300 calibre and the supercharged 59215 calibre provides a 192-hour power reserve on the “small” version. The black dial on this limited edition (1000 available) features markers (minute track, Arabic hour numerals, triangular marker at 12) in beige Super-LumiNova®. Unlike its big brother, it also features the date and power reserve indicator in addition to the hours and minutes in the centre tracked by blue propeller-shaped hands and the small seconds at 6.
