IWC's Ingenieur was made for the first time in the middle of the 1950's. With its self-winding mechanical movement, it was a sensation at the time, and has always been considered as the most resistant watch. This concept of wristwatch was meant to be constantly adapted to technical progress in the field. In 1976 will be launched the model "Ingenieur SL" antimagnetic to 80'000 Ampere/Meter and in 1989 the "Ingenieur R" antimagnetic to 500'000 Ampere/Meter.
