Not only was this watch created to withstand much, it was also designed well, with an elegant dial and a 36.5mm case diameter that wears boldly on the wrist.

The celebrated Ingenieur model was launched in 1955 and developed by Albert Pellaton, IWC's technical director responsible for the creation of the firm's first automatic movements. One of the key characteristics of the Ingenieur line is the watch’s resistance to magnetic interference. The distinctive and famous logo of an arrow passing through the name "Ingenieur" is a reminiscent of the Swiss thunderbolt icon which was chosen to mark the model's anti-magnetic properties, the soft iron shield protecting the movement against magnetic shields.

For many connaisseurs, the Ingenieur 666AD remains the quintessential tool watch, boasting a classic design and incorporating a highly-useful date-function, indicated by the letter ‘D’ in the reference number. Whether you’re a scientist or just need a robust watch with a fascinating story, the Ingenieur is it.
