    Accompanied by IWC International Guarantee and Certificate of Origin dated February 1991, operating instructions, fitted presentation box and outer packaging.

    The celebrated Ingenieur model, often affectionately called "Inge" by watch aficionados, was developed by Albert Pellaton, IWC's technical director responsible for the creation of the firm's first automatic movement, 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.

    The upgraded reference 3508 was launched in 1989 and tested to 500,000 a/m, rendering this watch probably the most anti-magnetic watch ever made.
