Orient Professional Saturation Diving Watch
Concept
There
are many different types of diving, including skin
diving such as snorkeling, diving with equipment
such as scuba diving, and specialized diving for
deep-sea salvage or drilling underwater oilfields.
This product is aimed primarily at the specialized
diving used for deep-sea salvage and oilfield drilling.
It is a watch for professionals that is compatible
with saturation diving.
What
is Saturation Diving?
Normally, a human breathes in an environment of
atmospheric pressure (1 atmosphere). When pressure
increases during a dive, inert gases from the air
(such as nitrogen and helium) are breathed in and
absorbed in the body’s tissues. Nitrogen is
particularly dangerous because when a large amount
is absorbed in the bloodstream it has a narcotic
effect. Even worse, nitrogen forms bubbles in the
blood during decompression and may result in death.
With saturation diving, prior to a long dive the
diver is exposed to helium instead of the dangerous
nitrogen. The driver’s body absorbs as much
helium as possible to create a safe saturation condition
in his/her body.
To
create this condition before a saturation dive,
the diver enters a DDC (Deck Decompression Chamber)
on the surface together with his/her equipment (including
his/her watch). In this chamber, the pressure is
increased as required in a mixed-gas atmosphere
of oxygen and helium. The diver then moves to a
predetermined water pressure in an SDC (Submersible
Decompression Chamber), from which he emerges to
perform the required work. When returning to the
surface, this procedure is reversed to slowly decompress
the diver.
What
is a Saturation Diving Watch?
If a watch with a regular water resistant design
is worn during saturation diving, small helium gas
molecules could penetrate the gasket and enter the
inside of the watch. This would raise the internal
pressure and break the watch when surfacing. To
resolve this issue, most watches either have an
escape valve that is used to adjust the internal
pressure as required, or use materials in watch
parts such as the gasket that make it difficult
for the helium to penetrate.

Orient
Professional 300M Saturation Diving
Watch |
Features
This watch has a special case design that prevents
the penetration of helium gas. This means that the
internal pressure hardly rises at all, eliminating
the need for an escape valve. The diver no longer
has to use a valve to adjust the pressure inside
the case when diving or surfacing. The watch has
a water resistant design that is effective up to
a depth of 300 meters (984 feet), with a strong
exterior made from “SUS316L” material,
which has excellent corrosion resistance. The watch
has a large crown and rotating bezel, which makes
it easy to operate even when wearing gloves. The
band also comes with a new type of buckle that allows
the watch to be put on in a one-touch operation.
As well as when worn directly on the wrist, it also
fits well over a wide variety of diving wear.
This diver’s watch will satisfy both professionals
and diving enthusiasts who seek the genuine article.
