This diver’s watch will satisfy both professionals and diving enthusiasts who seek the genuine equipment for deep diving. 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 and compatible with saturation diving. To fully understand this watch, we must first explore the effects of saturation diving and the requirements of a saturation watch, which you can read down further below.

This watch has time and power reserve indicator as their major functions. At full charge, the watch’s power reserve is 40 hours, which means who can wear it every other day. The Power Reserve indicator, which you can see near the 12 position on the dial, is a guage that lets you know how much power the spring has, in useful units of hours. The dial color is black and has large luminescent hour indexes so that the user can read the time underwater. The crystal used in this watch is over 5mm in thickness.

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 caseback is screwed in by design with Orient’s traditional lion emblem, which requires a special caseback opener.

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. The buckle also is easy extendible, so that that you do not need to constantly resize the watch for your wetsuit. As well as when worn directly on the wrist, it also fits well over a wide variety of diving wear.

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.
