1976 was a prolific year for Gerald Genta, following up on his Royal Oak design from 1972 with two additional takes on the concept with the Patek Philippe Nautilus, and a reimagining of IWC’s Ingenieur. The IWC Ingenieur reference 1832 SL has a slightly different place in history than the Royal Oak and Nautilus for a variety of reasons (which I explore further in this review) but there’s no denying the impact it had on a very different part of the market, both then and now. 2026 marks 50 years since Genta put his mark on the Ingenieur, and IWC is celebrating with the release of two limited edition references that feature vertically brushed silver dials in a wonderful nod to the watch’s past.
The Ingenieur has seen a diverse range of configurations across its lifetime, which actually began in 1955 with the reference 666. The Genta designed Ingenieur often made use of checkered or patterned dials, as was popular at the time (see original example of the above cited watches for proof), but exceptions did exist. One such example can be found within the very 1832 reference range (and another in the reference 3303) which used a silver dial with a subtle vertical brush. This is the route IWC has chosen to honor the original SL and 50 years of the Genta Ingenieur in the form of two limited editions.
IWC is releasing this anniversary design in both 40mm and 35mm form, which is a welcome move that should also serve as a reminder of just how good the 35mm Inge really is. Both use a familiar framework seen throughout the modern Ingenieur collection, which means an integrated bracelet, a trim case that measures ~10mm in thickness, and crown guards. What’s new are their brushed silver-plated dials, which forgo the usual basketweave texture of all other Ingenieurs in favor of a cleaner throwback reference. The choice brings out an entirely different personality, and I think it works quite well.
Another small detail that’s been added to the dial is the number 50 just below the lightning bolt framing of the Ingenieur logo. It’s subtle and effective without feeling over the top, but I also don’t think it was entirely necessary when the rest of the dial represents such a departure from the rest of the collection. Still, it could have been much worse. In addition to the dial, I think the removal of the crown guards would have been a nice touch, and created a more direct reference to the design’s origins in the process.
The rest of the watch remains as good as the rest of the collection, using a caliber 32111 behind a closed caseback in the 40mm, and a caliber 47110 under an open caseback in the 35mm. IWC will create 1,150 pieces of both sizes, with small but notable premium over their regular production counterparts. The 35mm is priced at $12,900, while the 40mm is priced at $15,000. Yes, the pricing is still a tough pill to swallow, but the collection seems to have found its footing at this point so it kind of is what it is. My hope is to see similar dial options make their way into the regular production collection. IWC
