In addition to the technical innovations involved, the IWC Ingenieur Jumbo looks just fabulous and has a modern size – it is exactly the kind of vintage timepiece any collector covets. The heavy steel case has a satin-finished middle part, the flanks are polished. The wide bezel also has a satin-finished surface and five recesses for a spanner. The black dial has a lively waffle structure on which the shiny steel indices and hands are beautifully accentuated. The watch is fitted with IWC's anti-magnetic in-house calibre IWC 8541B that uses the famous Pellaton winding system.
The timepiece is in outstanding condition, with minor signs of wear, and is rarely offered on the market.


This cult wristwatch was designed by Gerald Genta in the 1970s. His name stands for creative watchmaking; Genta has no interest in conventions and trends but succeeds in finding ever new ways of telling the time. For decades he developed successfull concepts and extraordinary designs for major watchmakers - designs such as, for example, the Patek Philippe "Nautilus", the Audemars Piguet "Royal Oak" or the IWC "Ingenieur"; a whole era of Swiss watchmaking bears his mark. Today many of these watches are highlights in the collections of the most exclusive brands and Genta started his own trade name in the late 1980s with great success.
