IWC Schaffhausen Big Pilot's Watch Constant Force Tourbillion

Crafted from 18-carat Armor Gold®, the Big Pilot’s Watch Constant Force Tourbillon features a tourbillon with IWC Schaffhausen’s patented constant force mechanism, which transmits perfectly even impulses of force to the escape wheel. The Big Pilot’s Watch Constant Force Tourbillon features a 46.2-millimetre case crafted from 18-carat Armor Gold®. Thanks to an improved microstructure, this innovative material offers significantly better hardness values than conventional red gold alloys – a meaningful advantage for a watch of this size and presence, built to be worn and used every day. The gold case is complemented by a black dial featuring a louvred, ring-shaped structure.
