The IWC Pilot's Watch Chronograph Spitfire was first introduced in 2004 as a more luxurious version of the brand's iconic pilot's chronograph. While the dial and movement remain unchanged, the new Spitfire features a more intricate design with applied numerals and different textures. The hands have also been updated to the alpha/sword style. You can choose between a black or silver dial, and the option of a leather strap or stainless steel bracelet. The earlier versions use the caliber 7922, while the later models use the 79320. There are also different versions available for the black dial, each with a unique language for the date display and an alligator strap or stainless steel bracelet.
