In 1941, the Royal Air Force approached IWC Schaffhausen to design a wrist watch resilient to strong magnetic fields, fluctuating temperatures, and rapid changes in air pressure – all common ailments in World War II aeronautics. Today, over seventy years later, the reinvented Mark XII still stands at a pivotal crux of aeronautic and watchmaking ingenuity. A new chapter in the Mark’s life has begun with the recent release of the Mark XVIII. A contrasting slate blue dial and calfskin band compliment the simplicity and ideology of the classic pilot’s watch. Generously sized and cleanly arranged, the cockpit inspired ordering is a true nod to the brand’s aeronautic reputation.
