Launched in 2007, the Longines Legend Diver collection is a re-issue of a diving watch  dating back to the 1960s when marine exploration and diving by the armed forces, as well  as sportsmen and women, was at its height. The watches have retained the original design  with domed glass combined with the reliability of present-day watches. All timepieces  within this collection are fitted with an exclusive calibre: L888 for men and L592 for women.
