Explanation

See translation

“Ingenieur” — the German word for “engineer.”
During the 1950s, the world entered a period of rapid scientific and technological progress. As fields such as nuclear energy and electrical engineering advanced, more engineers found themselves working in environments exposed to strong magnetic fields.

In response to these demands, IWC developed a timepiece specifically for engineers. By adding a soft iron inner cage beneath the dial and behind the caseback—encased within a thick stainless steel case—they created a watch with outstanding anti-magnetic properties.

With its clean stainless steel design, substantial case thickness, and bold dauphine hands, this vintage IWC offers both strength and elegance. A timeless companion that seamlessly adapts to any occasion.
