Throughout its history, IWC Schaffhausen has engineered numerous mil-spec watches for different branches of the British military. These service watches were characterized by high-precision movements, extreme ruggedness, a functional design with easily legible dials, and purpose-built technical features. The Spitfire Pilot’s Watches reflect this chapter of the brand’s history. The Big Pilot’s Watch 43 Spitfire features the typical Big Pilot’s design with the striking conical crown in an ergonomic 43-millimetre case, combined with a distinct military aesthetic.
