IWC Pilot's Watch Mark IX

The Spezialuhr für Flieger (retroactively named Mark IX) is a pilot's watch produced by IWC from 1936 through 1944.

In 1936, IWC developed a “Spezialuhr für Flieger” (Special Watch for Pilots), with a large 36 mm case, black dial with luminescent numerals, and a rotating bezel. This watch was retroactively and unofficially named “Mark IX” to differentiate it from its successor, the famous Mark X created according to British Ministry of Defense specifications after World War II.

The Mark IX was a novel “flieger”, designed to be simple to read, with little superfluous decoration. The matte black dial features large luminous numerals inside the marked chapter ring. Wide cathedral hands are used, with luminous material to be visible in the dark.

The Mark IX uses a hand-winding movement, IWC's Cal. 83.

The Mark X was introduced in 1944 according to British Ministry of Defense specifications.
