A simple watch with three hands, the first Ingenieur (Ref. 666) raised the bar with its minimalist design, which IWC continued to refine from 1967 with the Reference 866. "The new collection is very much inspired by these early Ingenieur models, so the watch family is definitely going back to its roots. The influence is clear to see in the simple round case as well as in the dial with its striking hands and indices with luminescent elements," explains Christoph Grainger-Herr, the new CEO of IWC Schaffhausen.

The Ingenieur Automatic (Ref. IW357001/IW357002/ IW357003) is a simple watch with three hands, a date window at "3 o'clock" and a case measuring 40 millimetres in diameter. Three versions are available.

The Ingenieur family now has a striking vintage character and is lighter and more elegant in its overall appearance. The new collection covers a lot of bases with three automatic models, four IWC-manufactured chronographs and a limited-edition reference with perpetual calendar.

The Ingenieur Chronograph (Ref. IW380801/IW380802/ IW380803) is driven by the new IWC-manufactured 69375 calibre with a bidirectional pawl-winding system and a power reserve of 46 hours. All the watches feature a see-through sapphire-glass back that provides a view of the 69375 calibre.

The Ingenieur Chronograph Sport (Ref. IW380901) is driven by the IWC-manufactured 89361-calibre movement and is limited to just 500 watches. The small seconds hand in the shape of a lightning bolt at "6 o'clock" is a reminder that a soft-iron cage protects the movement against the negative influence of magnetic fields.

The top-of-the-range model is the Ingenieur Perpetual Calendar Digital Date-Month (Ref. IW381701). The per­petual calendar automatically recognizes the different lengths of the months, including the leap day occurring every four years; it is extremely easy and convenient to ad­just using the crown. The IWC-manufactured 89800 calibre also features a chronograph function. The timepiece with a 45-millimetre 18-carat red gold case, silver-plated dial, black hands and black alligator leather strap is limited to just 100 watches.
