Does the helium valve excite you? Well, it’s useful for commercial divers only; that too, only them doing very deep saturation diving. You need to live underwater for that, in habitats filled with a mixture of breathing gases, one of which is helium. The helium molecules are small enough to pass through the water/humidity protection of the watch and expand as it surfaces due to dropping pressure. This damages the watch. The valve, when opened, lets the helium escape.
