During Watches and Wonders 2023, IWC revisited its Ingenieur collection by debuting Ingenieur Automatic 40, a new collection of three steel-cased models, while also adding a new titanium version of the watch.
While we’ve seen titanium versions of the post-1976 Gerald Genta-designed Ingenieur in the past, this year’s debut is an all-new ongoing model that, from early notices, seems bound to be a hit for the Schaffhausen-based watchmaker.
With a name meaning ‘engineer in both French and German, the Ingenieur collection has been where IWC placed its most ‘technical’ designs over the years. IWC launched the collection in 1955 to highlight its first automatic movement protected with a soft-iron inner case for magnetic field protection.
This tool-watch focus remains as all the new Ingenieur Automatic 40 references are powered by the IWC-manufactured Caliber 32111, boasting a superior power reserve of 120 hours.
Also, all the new models feature soft-iron inner cases to protect the movements from magnetic fields, and all are water-resistant to 100 meters.
The latest Ingenieur collection traces its design from the 1970s, more specifically from Gérald Genta’s Ingenieur SL, Reference 1832.
On each Ingenieur Automatic 40 watch you’ll see five functional, polygonal screws along the bezel to secure the bezel to the case. These echo the Genta design, though on the original model the screws were not always in the same location along the bezel.
Here, a permanent pattern for the screws contributes to the case and bezel design while also enhancing the watch’s integrity.
To create its new, distinctive ‘grid’ pattern dial, IWC’s watchmakers stamp the pattern (small lines offset by 90 degrees to each other) into a soft iron blank, and then galvanize it.
The result is a pleasing texture and design that meshes nicely with the entire watch’s technical nature. A new, slightly curved case enhances the model’s wrist friendliness.
For the steel Ingenieur Automatic 40, IWC offers black, silver and aqua dials, while the titanium model is matched with a nice grey dial, notably darker than the silver-dialed steel model. 
The titanium watch (Ref. IW328904 ) is also sand-blasted with polished bevels and brushed sides.
Its sturdy integrated Grade 5 titanium bracelet with butterfly folding clasp maintains the entire watch’s lightness, which also contributes to the watch’s wrist-friendliness. Titanium’s anti-allergy properties are also a plus.
Price: $11,700 (steel) and $14,600 (titanium).
The watchmaker also engraves each watch’s individual serial number on the rim of the sapphire caseback.
The system is twice as efficient as a traditional winding system and contributes to the long seventy-two-hour power reserve of the UN-240 manufacture caliber inside.
The lightweight metal plus a newly integrated 30% recycled textured rubber strap (one of three included) combine to make the Freak One quite comfortable on the wrist.
