IWC · Family: Ingenieur
The IWC Ingenieur Automatic 40 IW328902 is the steel, silver-dial execution of the 2023 revival of Gérald Genta's 1976 design, with a 40mm case and integrated bracelet. It runs the in-house Calibre 32111, automatic, with roughly 120 hours of power reserve. Cazador has no verified price observations yet. Its standout detail: the grid pattern stamped onto a soft-iron base, a direct legacy of the Ingenieur's original antimagnetic purpose.

The Ingenieur was born in 1955 as an automatic watch built for scientists, engineers and doctors exposed to magnetic fields, protected by a soft-iron inner cage that shielded the movement. That first generation, round-cased and classically styled, bore little resemblance to the watch associated with the Ingenieur name today.
The decisive turn came in 1976, when Gérald Genta — already the author of Audemars Piguet's Royal Oak and Patek Philippe's Nautilus — designed the Ingenieur SL, reference 1832: an integrated-bracelet case with a screwed bezel featuring five visible screws, which pushed the collection's identity toward the language of 1970s luxury sport watches.
In 2023, IWC introduced a direct revision of that Genta design under the name Ingenieur Automatic 40: a 40mm case retaining the aligned five-screw bezel and integrated bracelet, with a more rounded profile and a curved line of varying thickness that lends a slender feel on the wrist. The collection launched with four executions: steel with a black dial (IW328901) or silver dial (IW328902, this fiche's reference), a more casual version with a turquoise Aqua dial (IW328903), and a titanium version (IW328904).
This reference's dial reproduces the grid pattern stamped onto a soft-iron base first seen on the 1976 SL Jumbo, here in a silver tone, with larger applied markers and indexes than earlier generations and luminescent treatment on both indexes and hands.
Inside is the Calibre 32111, an in-house automatic movement with a pawl winding system sharing architecture with other calibers from the group IWC belongs to, capable of storing up to 120 hours of energy — five days — thanks to its twin-barrel system. The bracelet, with more rounded H-shaped links than earlier designs, closes via a concealed butterfly clasp and lacks a micro-adjustment or quick-release system, as IWC designed this reference to be worn exclusively on its integrated bracelet.
Because it was born in 1955 as a watch built for scientists and engineers exposed to magnetic fields, protected by a soft-iron inner cage still present in the current generation.
The design is based on the 1976 Ingenieur SL, reference 1832, by Gérald Genta — the same designer behind Audemars Piguet's Royal Oak and Patek Philippe's Nautilus.
Both share the same 40mm steel case and Calibre 32111; the documented difference is dial color — silver on the IW328902, black on the IW328901.
Cazador has no verified price observations for this reference yet and does not publish estimates without its own data.
Up to 120 hours — five days — thanks to its twin-barrel system.
There's no documented interchangeable-strap or quick-release option for this reference; IWC designed it to be worn exclusively on its integrated bracelet.
Yes, up to 100 meters, a figure typical of an everyday integrated sport watch rather than a dedicated diving instrument.
