IWC SCHAFFHAUSEN has developed its'Pilot's'watches in close collaboration with top aviators since launching in 1936. Powered by an in-house calibre 82100 automatic movement that's visible through the case back, this'Big'version has been made in Switzerland with a robust 43mm stainless steel case and'Racing Green'dial set with easy-to-read luminous hands and indices. It's fitted with the signature EasX-CHANGE system, so you can easily switch the rubber strap to a leather one, depending on the occasion. For warranty information, please refer to details & care
