European Watch Clock and Jewellery Fair 1981 BF 313
The “Ingenieur SL” model is the leader of IWC’s collection of advanced quartz wristwatches. In stainless steel, super-antimagnetic and particularly shock-resistant, it is thinner and more stylish than ever. Two new models (right) now joint the existing range, raising to four the number of “Ingenieur SL” models available. (IWC International Watch Co., Schaffhausen)
