IWC Ingenieur
This wristwatch was made for the first time by IWC 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.
