Rolex Watchmaking – Helium Escape Valve

Описание: Our helium escape valve, patented in 1967, protects our watches designed for extreme diving. Rolex invented it so that helium used for dives in hyperbaric chambers could be released during decompression. The valve triggers when pressure inside the case is too high. Thus, hermeticity is never compromised. The self-regulating system comprises a hermetic cylinder, a piston, a seal and a spring. Because when it comes to depth, the feat lies not only in the descent, but in returning to the surface.
