The Swiss Manufacture IWC Schafffhausen has been producing timepieces of lasting value since 1868. The Mark XI entered military service in 1949, issued to pilots in the Royal Air Force, Royal Australian Air Force, Royal New Zealand Air Force and was decommissioned in the early 1980’s. It served as the debut for the legendary manually wound caliber 89 created by Albert Pellaton. Caliber 89 is considered to be one of the most robust and reliable manually wound movements of all time.
To meet the requirements for anti-magnetism, IWC encased the movement in a soft iron covering underneath the screwed case. Issued to the Royal New Zealand Air Force the present Mark XI pilot’s watch, with fixed spring bars, luminous dial and hands and hacking seconds, is a robust navigation machine and adorable, both for its versatility and as an important horological innovation. Besides its rich history, the Mark XI with a 36mm case diameter, is a great all-around watch with excellent style, and wears beautifully on a ladies wrist too.
