A gas escape valve or Helium release valve serves to allow Helium gas and other gas molecules which are inside the diving watch's casing to flow out of the watch. This is a feature which is only relevant for the most extreme form of professional diving, the so-called saturation diving using Helium containing gas mixtures and long decompression phases, to which no recreational diver and not even the great majority of professional divers ever comes close to. According to the data referenced in saturation diving, of the 3,300 commercial divers employed in the United States in 2015, only 336 were saturation divers. Thus, the presence of this feature in diving watches is usually not at all required unless it is intended for exactly this application, nevertheless a greater number of typically high-priced diving watches have it. Further information: an article on a commercial website about the issue.
