The Ingenieur has been a cornerstone re-release for IWC. For Watches and Wonders 2026, we see more additions to this line to satiate buyers looking for something slightly different. These cover smaller case sizes, case materials, and complications.
The Ingenieur didn’t always look like what it does today. It actually debuted in the 1950s as a beefed-up watch within the IWC lineup, when the brand decided to add a Faraday cage to what were essentially standard daily watch designs. These vintage models, like the reference 666, are some of the most beautiful tool watches ever made, in my humble (and biased) view. However, it’s Gérald Genta’s thoroughly revamped Ingenieur design from the 1970s that IWC has brought back with renewed fervor. In fact, this is a special year for the brand, as it marks the 50th anniversary of the Gerald Genta-designed Ingenieur SL ref. 1832. Let’s take a look at the new models released at Watches and Wonders.
The Ingenieur Automatic 35 refs. IW324911 and IW324907
First up are a couple of new options for the mid-sized 35 × 9.4mm model. I have spent time with the 35mm Ingenieur in stainless steel (with a silver/white dial) and found it to be an enchanting, truly unisex size. The Ingenieur Automatic 35 ref. IW324911 is the first model in the current Ingenieur collection to feature diamonds. Its screw-on bezel is 18K 5N (red) gold and embellished with 45 white diamonds, totaling 0.7 carats. The dial maintains the current collection’s grid pattern inspired by Genta’s 1970s Ingenieur design. Atop the dial sit gold-plated appliques and hands. All of these feature Super-LumiNova except for the seconds hand and date frame.
Ref. IW324907 is a more straightforward steel option, introducing a blue dial to the 35mm collection. The brand says it has been making watches with blue dials since the late 1960s, with one of the earliest models having been the Ingenieur Automatic ref. 866AD.
Both watches feature transparent case backs showing IWC’s 47110 caliber. This 23-jewel automatic movement has a 4Hz (28,000vph) frequency and a 42-hour power reserve. It’s finished with perlage, concentric Côtes de Genève, blued screws, and a gold-plated rotor. It’s nice to see these models keep the standard 10-bar water resistance rating. This keeps them ready for adventure, even if the diamond-set IW324911 (€18,800 / US$18,700 / CHF 17,500) may not be the go-to choice for outdoor expeditions. The blue-dial steel IW324907 (€11,300 / US$11,200 / CHF 10,500) is likely to see more action in that regard.
The Ingenieur Automatic 42 ref. IW338902 in dark olive-green ceramic
IWC typically makes its ceramic watches slightly larger than their metal counterparts, and this next Ingenieur is no exception. This 42 × 11.5mm IW338902 ties for the largest case in the current Ingenieur collection, and it comes in a beautiful dark olive-green ceramic. The ceramic’s color seems to riff off what we saw with the custom Ingenieur that Hollywood star Brad Pitt was spotted wearing (a steel Ingenieur with a green dial).
The use of a green ceramic case in the larger model makes for a visually imposing watch, to be sure. I very much liked the black ceramic 42mm Ingenieur when that was released. It reminded me of the blacked-out Porsche Design watches from the 1980s. The use of dark green is an interesting choice.
IWC says using colored ceramic is made by mixing zirconium oxide with other metallic oxides in a precisely defined ratio. According to the brand, as the color changes during the sintering process, achieving a uniform shade across different components is highly complex.
I’ve visited the IWC factory in Schaffhausen and seen some of this process. I can attest to how complex it is. The addition of components in 18K 5N gold, including the crown and the screws that lock the bezel to the case, is a cherry on top. This watch also has a 10-bar water resistance rating, meaning you can definitely take this one ocean swimming, if the mood should strike you. Inside beats the automatic IWC-manufactured 82110 caliber. It has a 4Hz frequency, 22 jewels, and a power reserve of 60 hours. This dashing Ingeneiur Automatic 42 ref. IW338902 retails for €23,700 / US$23,800 / CHF 22,000.
The Ingenieur Perpetual Calendar 41 (ref. IW344904) in titanium
IWC has a long and storied history of using titanium in its watchmaking. Today, we have the material applied to an example of the Ingeniuer with a perpetual calendar. The regular time-and-date Ingenieur already has an example in titanium, but this silver-dial beauty helps push what we can expect from the watch line.
The 41.6mm case has a 13.2mm profile and houses the 46-jewel IWC-manufactured caliber 82600. This 4Hz movement provides a 60-hour power reserve and features an automatic Pellaton winding system. As a perpetual calendar, it displays the day, date, and month, each in a separate sub-dial, along with a small indicator for the leap-year cycle within the register at 9 o’clock. And though not necessary for a perpetual calendar, it also features a moonphase display in the lowermost sub-dial.
Despite the perpetual calendar’s complexity, the watch retains the Ingenieur’s standard 10-bar water resistance. No doubt, the lack of extra holes for calendar correctors aids in this, as the caliber allows the wearer to make all adjustments via the crown. Overall, the Ingenieur Perpetual Calendar 41 ref. IW334904 is a handsome watch that looks like a tool but offers high-horology complications. It retails for €44,100 / US$44,000 / CHF 41,000.
The Ingenieur Tourbillon 41 ref. IW345901 in red gold
Last but certainly not least, this piece from IWC will be limited to just 100 pieces. The Ingenieur Tourbillon 41 ref. IW345901 features a 41.6 × 12.1mm case. Both it and the bracelet are made of 18K 5N gold, and the dial contrasts with these features quite well. Notably, while the dial looks brown in our photos, its true green color was simply difficult to capture due to lighting restraints.
Inside lies the IWC-manufactured 82905 caliber, ticking away at 4 Hz. It uses a Pellaton winding system and has a power reserve of 80 hours. Some of the winding system’s components are made of ceramic to reduce wear and tear. IWC says particular attention was paid to the finishing on the caliber of this watch, including the automatic bridge and rotor, which are both gold-plated and decorated with Geneva stripes. The rotor features an integrated “Probus Scafusia” medallion crafted from solid gold. Visible at the 6 o’clock position on the dial, though, is this model’s party piece…
The flying one-minute tourbillon of the Ingenieur is suspended from gold-coated bridges. Consisting of 56 individual parts, the mechanism apparently weighs just 0.635 grams. Make no mistake, though; an 18K gold watch of this size certainly won’t be a featherweight! And with a price on request, I’m sure it’s not for the faint of finances either.
Concluding thoughts
These releases represent IWC’s further investment in the Ingenieur line. It is quickly turning into one of the most important pillars for the brand. This is a good thing, as buyers will want options in this category, and IWC has a rightful claim with the Gérald Genta design history.
I’d still like to see a close re-edition of the original Ingenieur, but perhaps this is a fool’s hope. In the meantime, we have an expanded line of integrated-bracelet options from IWC, and these watches seem to target different areas of the market, which is also good. But what do you think, Fratelli? Do any of these new releases speak to you? Let me know in the comments.
