Though launched in 1955, IWC SCHAFFHAUSEN's'Ingenieur'line is most notably associated with the'SL'model designed by Gérald Genta in the'70s, which is what this reference is based on. It has a sleek stainless steel case complete with a screw-on bezel and an easy-to-read black dial that's detailed with lines offset to each other by 90 degrees, creating a distinctive grid structure. Honouring the original's technicality, a soft-iron inner case shields the in-house calibre 32111 automatic movement from magnetic fields. For warranty information, please refer to details & care
