THE HEART OF THE
ROLEX DEEPSEA MODEL
HELIUM ESCAPE VALVE
Professional saturation divers spend
long periods of time in a hyperbaric
chamber, where the gas mixture they
breathe contains a significant proportion
of helium. The molecules are so small
that they penetrate the watch case.
During the decompression phase that
enables divers to gradually eliminate the
gas mixture absorbed by their bodies
and returns them to normal atmospheric
pressure, the helium cannot always
escape from the watch case sufficiently
quickly. This phenomenon can result
in a build-up of pressure inside the
timepiece, leading to damage or even
separating the crystal from the case.
