Just like the Patek Philippe Nautilus and the Audemars Piguet Royal Oak, the IWC Jumbo Ingenieur was another genius design by Gerald Genta. Housed in a jumbo stainless steel amagnetic case, just like his other 2 creations, it featured the 8541 ES caliber, which was not only amagnetic but also featured a stop-second function. Made in only approximately 542 pieces, this is an opportunity to acquire a classic from Gerald Genta that will certainly become a future collectors piece, similar to the Royal Oak and Nautilus.
