The IWC Pilot's Watch Chronograph Spitfire was released in 2004 as a fancier version of IWC's famous pilot's chronograph. The dial and movement are the same, but the dial has more details like applied numerals and different textures. The hands are now a cool alpha/sword style. You can get the 3706 Spitfire with a black or silver dial, and choose between a leather strap or stainless steel bracelet. The earlier models have the caliber 7922, while the newer ones use the 79320. There are also different variations of the black dial, with different languages for the date disc and either an alligator strap or stainless steel bracelet.
