IWC Schaffhausen introduces the Ingenieur Automatic 40 at the Watches and Wonders exhibition in Geneva. This newly engineered automatic model reflects the bold aesthetic codes of Gérald  Genta’s Ingenieur  SL, Reference 1832, from the 1970s while meeting the highest standards regarding ergonomics, finishing, and technology.

Watches and wonders 2023: new from IWC – the Ingenieur Automatic 40

The collection encompasses three references in stainless steel and one in titanium. The Ingenieur Automatic 40 is powered by the IWC-manufactured 32111 calibre with a power reserve of 120 hours. All new models feature soft-iron inner cases to protect the movements from magnetic fields and are water-resistant to 10 bar, making them fully versatile sports watches for the 21st century.

Press Release details

In the 1970s, IWC Schaffhausen commissioned the renowned Geneva watch designer Gérald  Genta to redesign the Ingenieur. The Ingenieur had originally been introduced in 1955. With the first automatic movement developed in Schaffhausen and a soft-iron inner case for magnetic field protection, this watch marked a technical milestone for IWC – also evident in the name Ingenieur, the word used in German and French for Engineer. With his unique artistic signature, Genta succeeded in giving the Ingenieur a new, highly distinctive visual identity. His Ingenieur SL, launched in 1976 as the talking piece of IWC’s SL collection of steel luxury watches, featured bold aesthetic codes such as a screw-on bezel with five recesses, a dial with a unique pattern, and an integrated H-link bracelet. With its innovative and disruptive design, the Ingenieur SL was ahead of its time. Today, Gérald Genta’s creation is a collector’s favourite and one of the most sought-after models from the history of IWC.

The overall dimensions of the case have been carefully reworked and improved down to the smallest detail. The lug-to-lug distance of 45.7 millimetres ensures perfect ergonomics and excellent wearability, even on a slender wrist. While the Ingenieur SL from the 1970s had nose-shaped horns, the new Ingenieur Automatic  40 features a newly engineered middle-link attachment. Aesthetically similar to the Ingenieur SL, this new solution enhances the ergonomics and provides an even better fit on the wrist. The curved casing ring further improves the ergonomics of the case.

One of the most striking changes of the new model is the introduction of functional, polygonal screws on its bezel. For the Ingenieur  SL, a bezel with five recesses was screwed onto the case ring. As a result, the recesses ended up in a different position on each watch. With the Ingenieur Automatic  40, five screws secure the bezel to the case. The screws now have a technical function and, as a result, are always in the same position. In addition, the dial features a distinctive “Grid” structure, creating a balance to the technical and very sculptural case design. Consisting of small lines offset by 90 degrees to each other, it is stamped into the soft iron blank before it is galvanised. Finally, appliques with luminescence add additional depth and ensure easy legibility, even at night. 

The Ingenieur Automatic 40 features an astonishingly high level of detail and finishing. The case, bezel, and bracelet are elaborately finished using a combination of polished and satin-finished surfaces. The upper parts of the bracelet contain closed links without pins, accentuating the outstanding craftsmanship. The integration of an elaborately finished butterfly folding clasp highlights the beauty and thinness of the H-link bracelet. In addition, a newly designed crown protection further underscores the sporty character of the timepiece.

The Ingenieur Automatic  40 is powered by the IWC-manufactured 32111 calibre with an automatic pawl winding system and a power reserve of 120 hours. In keeping with the tradition of the Ingenieur, a soft-iron inner case efficiently protects the movement from the effects of magnetic fields on its accuracy. Moreover, the case is water-resistant to 10 bar, making the Ingenieur Automatic 40 a modern and fully versatile sports watch. The Ingenieur Automatic  40 is available in three references in stainless steel: 

  • Ingenieur Automatic 40, Ref. IW328901: stainless steel case, black dial, rhodium-plated hands and appliques, integrated stainless steel bracelet with butterfly folding clasp 
  • Ingenieur Automatic 40, Ref. IW328902: stainless steel case, silver-plated dial, rhodium-plated hands and appliques, integrated stainless steel bracelet with butterfly folding clasp
  • Ingenieur Automatic 40, Ref. IW328903: stainless steel case, aqua dial, rhodium-plated hands and appliques, integrated stainless steel bracelet with polished centre links and butterfly folding clasp 

IWC is also presenting one version of the Ingenieur Automatic  40 in titanium. Titanium is about one-third lighter than steel. Other distinguishing features of this material are its skin-friendliness and anti-allergic properties. However, the robust and rugged metal is also incredibly difficult to machine. IWC pioneered titanium in the watch industry in the 1980s and has since acquired unique expertise in this field. The Ingenieur Automatic 40 with a grade 5 titanium case and bracelet features a highly detailed finish with sandblasted, satin-finished, and polished surfaces. The grey dial, as well as the black hands and appliques, further accentuate the characteristic matte grey look of the titanium.

All new Ingenieur Automatic  40 models are available through selected IWC boutiques. Additionally, it is eligible for registration under the My IWC care program, benefitting from a 6-year extension to the standard 2-year International Limited Warranty.

    Alguien por ahí de este mundillo dijo una vez, “Desenterrar el pasado puede ser un paso en falso en las relaciones humanas, pero en la relojería es una bendición”. Yo le añadiría “A veces”, y también “casi siempre para mayor beneficio de sus fabricantes”. Repetir diseños del pasado mantiene el legado y nos permite disfrutar de equipos que demostraron su fiabilidad pasando la prueba del tiempo. Pero indudablemente nos trae aparejado un freno a la creatividad. Estos bellos IWC ingenieiur de hoy pertenecen a ese grupo “jugada rápida” para encestar dinero facil. Puro maquillaje con precios de cirugia total. Ojalá les salga bien el plan en estos difíciles tiempos que corren. Aprovechando viejas glorias en sus formas exteriores, no son capaces, al menos, de lucirse en la mecánica. El calibre utilizado de Val Fleurier es a IWC lo que Kenissi a Tudor. Mucha gente chupando de esas “Manufacturas”.
