HELIUM VALVE (AUTOMATIC )
The security helium valve is a distinct element of professional
diving watches. It proves its usefulness in all instances where the
watch is used for working in deep depths and during long diving
activities, for instance in diving bells, i.e. in ambiences where you
breathe in a mixture of helium and oxygen. Because helium has
such a miniature atomic structure, it can easily penetrate into the case. That is why there is a valve that
allows helium, accumulated inside the case at a high pressure, to escape, because otherwise the glass
could be expelled forcefully in the emerging phase.
