The Engineer Hydrocarbon NEDU is the world’s first diving watch with a helium release valve incorporated into the crown.

One of the many requirements imposed by deep-sea diving to the watchmaking instruments is the escape of helium gas. During their descent into the depths, deep-sea divers are generally placed in a diving bell where they are exposed to an air that is enriched with helium. The pressure is also gradually increased to reach the depth pressure. The watch is then penetrated by tiny helium molecules. When going back to the surface, the excess of internal pressure in the watch due to the helium molecules can generate irreparable damages to the watch.
