το ORIENT 300M SATURATION DIVER
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.
