The Ingenieur SL was created by the great Gérald Genta. Famous for designing the Patek Philippe Nautilus and the Audemars Piguet Royal Oak he significantly changed the appearance of the 3rd generation of the Ingenieur-Line. Its eye-catching design stood for toughness; rugged and sporty, with undeniable technical appeal. The watch is powered by IWC's caliber 8541ES which contains special amagnetic parts. The Ingenieur SL also has a special dust cover to protect the watch from magnetic activity.
This example, is housed in a 40mm stainless steel case and comes with a fine chequered guilloché black dial, primarily developed to absorb reflections. Despite its qualities, the Ingenieur SL was not a good seller for IWC due to its large size and its heavy weight of almost 150gram. Under todays standards it is a perfect size watch. All in all, between 1976 and 1984 less than 600 pieces of the automatic model were produced. This sought-after and iconic watch comes with an extract of the IWC archives.
