The IWC Pilot’s Watch Mark XV Spitfire (Reference IW325313) is a highly collectible, upscale iteration of IWC's classic military aviator series. Produced between 2003 and 2005, it transitions the traditional, sterile instrument aesthetic of the standard Mark XV into a more dynamic and refined design. Depending on its specific production year, the watch is driven either by the IWC Caliber 37524 or Caliber 30110 (both heavily upgraded, chronometer-grade movements based on the robust ETA 2892-A2 platform). IWC modified these ebauches in-house by swapping out the gear trains, mainsprings, and regulators to maximize impact resistance and accuracy. It operates at a high beat frequency of 28,800 vph, provides a 42-hour power reserve, and features a quick-set date calendar at 3 o'clock alongside hacking (stop-seconds) functionality.
