The History of IWC Ingenieur

The IWC Ingenieur watch, launched in 1955, was specifically designed for men engaged in scientific and exploration pursuits. Similar in positioning to the Rolex Milgauss, the Ingenieur was introduced around the same time, offering water resistance, anti-magnetic properties, and precise, reliable timekeeping. Its hallmark is a lightning bolt striking from the upper left to the lower right across the “Ingenieur” name, symbolizing its flawless performance against any interference.
In the 1970s, renowned watch designer Gérald Genta crafted the Ingenieur SL for IWC. Fast forward to 2023, IWC introduced the Ingenieur Automatic 40, modernizing this iconic piece while retaining its bold aesthetics and unique personality. The new model aligns with ergonomic designs, surface treatment craftsmanship, and technical excellence, paying homage to the engineering marvels of the 1950s, an era that celebrated innovation and progress.
