The Ingenieur Automatic 40 is IWC's revival of the watch Gérald Genta drew in 1976, the Ingenieur SL ref. 1832. Steel case, steel bezel held by 5 screws, integrated bracelet, no gaps anywhere. IW328907 is the blue-dial version, and it is the one I want.
Why the blue one
The blue is the only thing that changed when IWC added it in December 2024, and it is the change that makes the watch. The black reads as a tool. The silver reads as a dress watch pretending to be sporty. The blue does the thing the Genta formula is supposed to do: look like one object, and hold the light differently depending on where you stand.
The dial is not painted. It starts as a soft iron blank, gets the grid pattern stamped into it in negative relief, and is then PVD-coated to the dark blue. The grid is Genta's 1976 pattern, enlarged. Rhodium-plated applied markers, lume-filled hands.
Using soft iron for the dial is not decoration. It is part of the antimagnetic cage, along with the inner case, which is the Ingenieur's whole reason for existing since 1955.

Background
IWC launched the Ingenieur in 1955 as an antimagnetic tool watch, built around a soft-iron inner case for engineers working near electrical equipment. It was a technical watch with no design pretensions.
Genta changed that in 1976. The Ingenieur SL ref. 1832 put the movement in a steel case with a screwed bezel and an integrated bracelet, in the same run of thinking that produced the Royal Oak in 1972 and the Nautilus in 1976. It sold badly at the time. It is now the reference point for the whole collection.
The 2023 relaunch as the Ingenieur Automatic 40 is the closest IWC has come to the 1832 since. What it got right was restraint: the case is 40mm rather than the 42 of the previous generation, the ergonomics of the centre link attachment were reworked for narrow wrists, and the bezel screws are functional rather than decorative.
See IWC-ingenieur-42 for the larger version and IWC for the brand.
What is good
- The dial. Photographs do not do the grid justice. It is stamped, not printed, so it changes with the angle instead of sitting flat.
- 10.8mm over a 45.7mm lug to lug. Correct numbers for an integrated-bracelet sports watch. It goes under a cuff, which the 42 does not.
- 5 days of power reserve from a manufacture movement. Off Friday, still running Wednesday.
- Soft iron everywhere. Inner case and dial. The antimagnetic story is real engineering rather than heritage marketing.
- Bracelet finishing. Brushed with polished lateral bevels, and the transition into the case is properly done.
What is not
- No micro-adjustment on the clasp. At this price that is hard to defend. Rolex, Tudor and Omega all solved it. A steel bracelet you cannot tune by 2mm on a warm day is a daily annoyance.
- No quick release. The bracelet is the watch, so you were never swapping it, but the omission compounds the point above.
- 100m and a solid case back. Both correct for the design. Worth knowing there is nothing to look at behind it.
- The price. Around 13,000 EUR puts it against a Royal Oak conversation it cannot win on resale, and against a Nautilus it cannot win on availability. It wins on actually being buyable.
Where it sits
| Alternative | Why | Price band |
|---|---|---|
| Audemars Piguet Royal Oak 15510 | The original, and the reason this category exists | 30k+ EUR |
| !watches/zenith-defy-skyline | Same formula, 5Hz, more angular, half the money | 8k+ EUR |
| Vacheron Constantin 222 | The connoisseur's answer, gold only | 60k+ EUR |
| Chopard Alpine Eagle 41 | The closest direct rival in steel | 13k+ EUR |
| Tudor Northflag | The same idea at a third of the price, with a GMT | 5k EUR |
My take
This is the one I would buy in the category, and the blue is the reason. Genta's grid on a stamped soft-iron dial in dark blue is a better object than either the black or the silver, and it is the same money.
The missing clasp micro-adjustment is the one thing that would irritate me every day, and at 13,000 EUR it should not be missing. Everything else is right: the size, the thickness, the movement, the finishing, and the fact that the antimagnetic claim is structural rather than a story.
Try it in the metal before deciding on the colour. The blue photographs darker than it wears.
