IWC Pilot's Watch Mark X
The Mark X is a pilot's watch produced by IWC from 1944 through 1948. It was created to the Mark X specification of the British Ministry of Defense.
After World War II, the British Ministry of Defense created a specification for a pilot's watch and selected twelve companies to produce it. Along with well-known competitors like Omega, Jaeger-LeCoultre, Buren, and Eterna, IWC produced a Mark X watch for the MoD. All such watches featured similar markers, hands, and numerals and were marked by a “broad arrow” indicating British Crown ownership. IWC had previously produced a “Spezialuhr für Flieger” (Special Watch for Pilot's), which was retroactively and unofficially named Mark IX to differentiate it.
The Mark X is designed to be simple to read, with little superfluous decoration. The dial features numerals from 1 to 12 inside the marked chapter ring. Luminous markers are placed on the hours, with larger markers at 3, 9, and 12, contrasting with the matte black dial. Small seconds are in a subdial at 6 00. Unlike the predecessor, syringe hands are used.
The Mark X uses a hand-winding movement, IWC's Cal. 83.
The successor, the legendary Mark XI was introduced in 1948 with central seconds and different dial markings.
