For many, the magic is in the dial.  The Ingenieur is not about complications like multiple hands, subdials or moonphases.  Rather, the simple function of accurately telling time (and on some models the date) in a robust and classic design provides the key to attraction.  The design itself is timeless, classic and sporty all at once. As a recent IWC catalog said about the Ingenieur, “understatement is part of the family tradition.”  1958 advertisement states that the Ingenieur is “Ideal for all professional men who require a watch which is fully reliable, accurate and trouble free under all conditions.” The Ingenieur’s genesis dates from 1944 when IWC hired a new technical director, Albert Pellaton.  He was responsible for the creation of IWC’s first automatic watch, the calibre 81 (subseconds at 6) and the calibre 85 (central seconds, flat overcoil) in 1950.  The next generation, the calibre 852 (central seconds, Breguet overcoil) was the first automatic movement encased under a soft-iron core with the Ingenieur name. The Ingenieur was viewed by IWC as the automatic and civilian version of the famous Mark XI, a hand-wound antimagnetic classic whose fame and following grew as a modern pilot’s watch. The Ingenieur is not a spectacular or sexy watch nor was its introduction in 1955 widely anticipated.  Like the Mark XI, the Ingenieur is about function and the name translates literally to “engineer.”  However, because it was produced for the civilian market, the Ingenieur was offered in a variety of relatively elegant dial styles, as well as in 18kt and mixed (steel and gold) cases.  Today the timeless design of the watch puts it in the “classic” category and is testimony that its appeal has outlasted its long reign as the flagship of the IWC line. The reference 666 Ingenieur featured anti-magnetic protection up to 80,000 amperes per meter, exactly double the resistance of the SL model currently offered by IWC. Double. Newer, it seems, doesn’t always mean better. IWC CALIBRE 853 IS CALLED BY COLLECTOR WORLDWIDE ONE OF THE TECHNICALLY BEST AUTOMATIC MOVEMENTS EVER BUILT IN SWITZERLAND.
