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 millimeters, a green dial, and rhodium-plated hands.
