    With IWC Extract from the Ledger confirming the sale of the present watch on 21 February 1984 to IWC, Frankfurt am Main. Furthermore delivered with the original fitted presentation box.

    The Ingenieur, affectionately called "Inge" by aficionados of this legendary model, was developed by Albert Pellaton, IWC's technical director responsible for the creation of the firm's first automatic movements, calibres 81 and 85. Calibre 852, the next generation, was the first self-winding movement encased under an anti-magnetic soft-iron core, introduced under the name "Ingenieur" in 1955.

    In the mid 1970s, IWC decided to redesign the model in order to render it a more "fashionable" look, consequently commissioning the famous watch designer Gérald Genta with this task. The "modernised" Ingenieur as well as two new models, the Golf Club and Polo Club, were included in IWC's "Collection SL", the "SL" designation originally meaning "Steel Line". However with the consecutive inclusion of non-steel watches in the collection, the meaning of "SL" is now translated into "Sports Line".

    The newly designed Ingenieur SL, also known as the "Jumbo SL", was most probably launched in 1976 and available in stores as of 1977. Reference 1832 was fitted with the super-antimagnetic calibre 8541 movement and affectionately nick-named "Jumbo" or "Fat" Ingenieur because of its large size.

    Made in small series only, the Ingenieur ref. 1832 with its massive, masculine look is a highly coveted sports watch in today's market.
