The watch devoted to Cousteau is technically identical with the Aquatimer Chronograph. The distinctly puristic design of the dial references the look of the first Aquatimer released in 1967 – even with three subdials and a date and day display, the blue dial is remarkably uncluttered. The innovative external/internal rotating bezel with a SafeDive system designed to prevent inadvertent changes of the dive time boosts the practical use of the diver’s watch, as does the increase in water-resistance to 30 bar. The chronograph function handles single stop times and aggregate timing up to 12 hours, while the push-buttons can be activated even underwater. The engraving on the back of the cover shows “le Commandant” with his trademark woollen beanie.
