The helium valve was specifically developed for professional divers, who can work underwater for extended periods of time. During their breaks they rest in diving bells which are filled with a mixture of helium and oxygen. The helium molecules are so small that with extremely long dwell times and under high pressure, they can penetrate the watch case through the watch seals. So, there is a balance of helium molecules in the decoration chamber and in the watch case. During decompression an overpressure is created in the watch case. Helium molecules cannot escape from the watch case as quickly as, for example, from the body/tissue of a diver. The helium valve allows the excess pressure to escape from the watch case without the watch glass being blown off. For more information about watches that offer this feature:
