ROLEX

Deep sea divers in the 1960s experienced a troublesome phenomenon during their decompression in hyperbaric chambers, where they breathed a gas mixture composed of around 95% helium: the crystal of their watch would often pop off, rather like a champagne cork. To address this issue, Rolex invented and patented the gas escape valve for the Sea-Dweller in 1967. This one-way valve safely allows the helium trapped in the watch to be released at a given pressure during decompression, while preserving the tight waterproofness of the Oyster case.
