Official description

The Big Pilot’s Watch 43 Spitfire (Ref. IW329702) features a bronze case and crown as well as a titanium case back. Alongside copper, the bronze used by IWC also contains aluminium and iron. This specific composition makes the alloy around 50 per cent harder than standard bronze. Additional characteristics include the material’s exceptional biocompatibility and its ability to develop a unique patina over time, which will give each timepiece a distinct character and look of its own. The warm colour of the bronze harmonises with the military green dial and the gold-plated hands. Both the hands and hour markers have been coated with a luminescent material to facilitate readability at night. The timepiece is fitted with a green buffalo leather strap with a unique texture. The two new Spitfire models feature IWC’s EasXCHANGE system which allows the wearer to quickly and easily change the strap at the touch of a button without any additional tools. Several alternative strap options made from calfskin and rubber are also available as accessories.
