Notes

IWC, "Ingenieur SL"

Just like the Patek Philippe "Nautilus" and the Audemars Piguet "Royal Oak", the IWC "Ingenieur SL" was another genius design by Gérald Genta (1931-2011).

Housed in a "Jumbo" stainless steel antimagnetic case, just like his other two creations, it featured the IWC 8541 calibre, which was not only antimagnetic but also featured a stop-second function.

Made in only approximately 542 pieces, this is an opportunity to acquire a classic from Gérald Genta that will certainly become a future collectors piece, similar to the "Royal Oak" and "Nautilus".
