  • Catalogue Essay

    Longines reference 6921 was launched in the late 1950's and was marketed as the 'Skin Diver's Watch'. This diver's wristwatch was powered by an automatic movement and a highly luminescent dial and hands. Original advertisement from the late 50's suggests the watch remains waterproof as long as the crystal and backs are intact and is further enhanced with an anti-radiation shield underneath the dial.

    Featuring broad and angular lugs, case dimension and overall very good condition make it difficult to believe that the present watch is over half a century old. This Skin Diver was invoiced on 9 July 1959 to the company Longines-Wittnauer, which was at that time the agent for Longines in the US. Complete with product literature and original bracelet, the present watch can be considered a ultra-rare watch in beautiful and charismatic condition.

  • Artist Biography


    Swiss • 1832

    Auguste Agassiz founded Longines in 1832, and today is considered to be a pioneer in the evolution of the chronograph. During the 1930s, Longines' chronograph wristwatches were used as tools for wartime aviators and military personnel. As one of Switzerland's largest manufacturers, Longines was an important supplier of wristwatches to militaries of multiple nations.

    Today, they are owned by the Swatch Group and produce wristwatches for both men and women. Their vintage wristwatches continue to grow in desirability amongst collectors. Some of the most sought-after models include such oversized chronographs as the Lindbergh Hour Angle designed by Charles Lindbergh, Chronostop, Tre Tacche, A-7, Tasti a Spillo and Doppia Lanchetta.
