IWC first pilot's watch to have a constant force tourbillon and the first time that IWC has produced a watch with a "red hard gold" case. Hard gold is a special alloy that is much more scratch resistant (5-10x, according to IWC) than normal red gold. This hand-wound movement also features twin barrels offering 96 hours of power reserve, a moon phase display, and a power reserve. 3Hz frequency.
