Less is more: the Mark XX reduces the design and technical functionality of a pilot’s watch to its pure essence. It is the successor to the legendary Mark 11, a precise amagnetic instrument watch IWC developed in 1948 for the navigators and pilots of the British Royal Air Force. This version features a robust and corrosion-resistant stainless steel case with a diameter of 40 millimetres, a white dial, and black hands. The high-contrast dial with black numerals and indices, the triangular index at 12 o’clock, and luminous elements ensure easy readability in all lighting conditions. Precision is ensured by the IWC-manufactured 32111 calibre with automatic winding and a power reserve of 120 hours. The front glass is specially secured so that it cannot detach from its place even in the event of a sudden pressure drop. The Pilot’s Watch Mark XX is water-resistant to 10 bar and is fitted on a black calfskin strap with a pin buckle. Thanks to the integrated EasX-CHANGE® system, the strap can be easily exchanged for another without additional tools.
