  • Catalogue Essay

    The celebrated Ingenieur model was developed by Albert Pellaton, IWC's technical director responsible for the creation of the firm's first automatic movement calibres 81 and 85.

    Produced for the civilian market, the functional Ingenieur (German for engineer) was available in steel or gold as of 1954 with a variety of styles.

    The distinctive and famous logo of an arrow passing through the name "Ingenieur" is a reminiscent of the Swiss thunderbolt icon which warns of the presence of an electrical current. The thunderbolt symbol was chosen to mark the model's anti-magnetic properties, the soft iron shield protecting the movement against magnetic shields.

    Considered one of the earliest "tool" watches and with its distinctive, timeless design, the early Ingenieur model enjoys cult status amongst collectors and this present example, with a distinctive black lacquered dial and galvanic printing, will certainly appeal to collectors. The watch was sold on April 3rd, 1963. The watch furthermore retains its IWC rice grains bracelet manufactured by Gay Frères, the master bracelet maker of the 20th century.
