Since IWC relaunched the Ingenieur in 2023 with the Automatic 40, IWC Schaffhausen has been building the collection outward with clear intent—new sizes, new materials, and complications that feel earned rather than forced. For Watches and Wonders 2026, that progression reaches its apex. Fifty years after Gérald Genta's original Ingenieur SL defined the template, IWC introduces the collection's first tourbillon, and does so without apology for its ambition. The Ingenieur Tourbillon 41 in 5N gold is the flagship that the collection has been building toward.
Things to Know About the Watch
Limited to 100 pieces, the Ingenieur Tourbillon 41 (Ref. IW345901) is built entirely from 18K 5N gold—case, integrated bracelet, bezel, crown, and crown guards. The five functional screws that secure the bezel to the case back ring are made of 18K Armor Gold, an IWC proprietary alloy with significantly higher hardness than conventional gold. The case and bracelet links are satin-finished with polished edges, a combination that plays particularly well in gold, drawing out the angular geometry of Genta's underlying design.
The olive-green “Grid” stamped dial—a hallmark of the modern Ingenieur—contrasts the warm tones of the case, adding real depth and texture. Hour and minute hands are gold-plated; the appliques are solid gold, individually set by hand. The flying minute tourbillon sits at 6 o'clock, suspended from gold-coated bridges. The cage consists of 56 individual parts and weighs just 0.635 grams. An integrated tourbillon stop allows the mechanism to be brought to a complete halt for setting the time to the second. The pallet lever and escape wheel are treated with IWC's Diamond Shell technology, an innovative coating that reduces friction and improves energy flow.
The Movement
The Ingenieur Tourbillon 41 is powered by the IWC-manufactured calibre 82905. Its Pellaton winding system uses the rotor's motion in both directions to build an 80-hour power reserve. Components subject to high stress, such as the automatic wheel, the clicks, and the rotor bearing, are made from zirconium oxide ceramic, virtually eliminating wear. The automatic bridge and rotor are gold-plated and finished with Geneva stripes. The oscillating weight in 22K gold carries an integrated Probus Scafusia medallion.
On the Wrist & Price
A full 18K 5N gold case—quite heavy, weighing 264 grams—with a flying tourbillon is a statement that requires no qualification. What IWC has achieved here is not merely adding the complication to the Ingenieur platform, but integrating it in a way that feels architecturally considered. The tourbillon aperture at 6 o'clock, the satin-polished gold surfaces, and the olive dial pull the whole watch together. At a 100-piece limitation, this is the definitive expression of the current Ingenieur generation and one of the more consequential pieces from IWC in recent memory.
