The Big Pilot’s Watch 43 Spitfire features a military aesthetic with a bronze case and crown and a military green dial and gold-plated hands.
The case and crown are made of bronze, while the case back is made of titanium. The bronze used by IWC contains aluminium and iron as well as copper. This special composition makes the alloy around 50 per cent harder than conventional bronze. The IWC-manufactured 82100 calibre works inside the case. The Pellaton winding mechanism, reinforced with ceramic components, builds up a power reserve of 60 hours. An inner cage made of soft iron protects the movement from the effects of magnetic fields.
