Ingenieur Tourbillon 41

THE IWC SCHAFFHAUSEN INGENIEUR TOURBILLON 41 IN 18 - CAR AT 5 N GOLD WITH A FLYING MIN UTE TOURBILLON

Schaffhausen/Geneva, 14th April, 2026: IWC Schaffhausen introduces the Ingenieur Tourbillon 41 at Watches and Wonders in Geneva. The new flagship Ingenieur model pairs a case and bracelet crafted from 18-carat 5N gold with an olive green “Grid” dial. The highlight is the flying minute tourbillon at 6 o’clock, which rotates around its axis once every minute. This elegant and refined luxury sports watch is further distinguished by its highly detailed finishing, including techniques such as satin finishing and polishing. The IWC-manufactured 82905 calibre, featuring a Pellaton winding system with ceramic components, is visible through the sapphire glass case back.

With the new Ingenieur, IWC Schaffhausen revisits the bold and visionary design created by Gérald Genta in the 1970s, pairing it with enhanced ergonomics and a highly detailed finishing. Since the launch of the Ingenieur Automatic 40 in 2023, the Swiss luxury watch manufacturer has continuously extended the collection with new sizes, materials and complications such as the emblematic crown-controlled perpetual calendar from Kurt Klaus. IWC now introduces an exclusive new model featuring the undisputed “queen of complications” in fine watchmaking, the tourbillon.

Limited to 100 pieces, the Ingenieur Tourbillon 41 (Ref. IW345901) features a 41.6 millimetres case and an integrated bracelet crafted from 18-carat 5N gold. The characteristic bezel, crown protection and crown are also made of this precious metal. Securing the bezel to the case back ring, the five functional screws are made of 18-carat Armor Gold®, a material with significantly higher hardness values than conventional gold alloys. Featuring the characteristic “Grid” pattern, the structured dial is a hallmark feature of the Ingenieur and adds a stunning level of texture and depth. Its dark olive green hue beautifully contrasts the gold. The hands are gold-plated, and the appliques, which are individually set by hand, are made of solid gold. As it combines various techniques, the Ingenieur Tourbillon 41 also boasts a high level of detail in its finishing. The case, bezel and bracelet links are satin-finished and feature polished edges. Gold brings out the intricate lines and angles of the Ingenieur particularly well, underscoring the sculptural beauty of the Gérald Genta-inspired design.

The tourbillon places the balance wheel and the escapement inside a small cage that rotates around its axis once every minute. This continuous rotation counteracts the effects of gravity on the oscillating system, contributing to a highly accurate rate. The flying minute tourbillon of the Ingenieur Tourbillon 41 is placed at the 6 o’clock position and suspended from gold-coated bridges, providing a stunning visual spectacle. Consisting of 56 individual parts, the delicate mechanism weighs just 0.635 grams. Due to the high number and minuscule size of its components, the tourbillon ranks among the most complex complications for a watchmaker to assemble. Thanks to the integrated tourbillon stop, the mechanism can be brought to a complete halt, allowing the watch to be set with down-to-the-second accuracy. The pallet lever and the escape wheel are treated with Diamond Shell® technology, an innovative coating that reduces friction and enhances the flow of energy in the movement.

HIGH-END MOVEMENT WITH PELLATON WINDING 

The Ingenieur Tourbillon 41 is powered by the IWC- manufactured 82905 calibre. Its highly efficient Pellaton winding system utilises the rotor’s movements in both directions to reliably build up a power reserve of 80 hours in the mainspring. Components of the winding system that are subject to high stress are manufactured from virtually wear-free zirconium oxide ceramic. Among these are the automatic wheel and the clicks, which are crafted from black ceramic, while the rotor bearing is made of white ceramic. The movement also features a high level of detail in the finishing. As an example, the automatic bridge and the rotor are both gold-plated and decorated with Geneva stripes. The oscillating mass features an integrated “Probus Scafusia” medallion, crafted from solid gold and symbolising IWC’s commitment to craftsmanship and quality.
