As the 10th edition of the world’s largest solo, non-stop, unassisted round-the-world sailing race gets underway, Ulysse Nardin announces the most sustainable watch the company has ever made. The lightly gray-tinted sapphire crystal case back gives a partial view into the Ulysse Nardin manufacture movement’s open-worked automatic winding system and is decorated with a map showing the route of the Vendée Globe and with the words ‘THE ONLY SOLO UNASSISTED NON-STOP SAILING RACE AROUND THE WORLD’. The NyloFoil case back surround also indicates the watch’s 300-meter water resistance and the coordinates of the Ulysse Nardin manufacture in Le Locle. The watch is limited to 300 numbered pieces.
