Helium Escape Valve

15 September 2016 by Greg Kelly

Many professional dive watches are equipped with a helium escape valve, a watch feature geared towards professional deep sea divers. It allows the extreme pressure from the depths of the sea to escape the watch via a valve that automatically opens when the pressure is greater inside the watch than outside.
