True Divers Standards
All our watches are tested for ultra water tightness at 100 meters by industry’s highest water resistance standard the ISO 6425. The top quality solid stainless steel construction will prevent salt water from eating into the watch. And the fine Swiss craftsmanship will guarantee your watch will never break down under water. Their ability to perform flawlessly underwater for long duration and resistance against condensation provides the highest stability for under water professionals. Every watch is tested in 3 different Waterproof Test Machines for 5 days. One using air pressure and the final two using water.
We perform some of the most extensive water resistance testing. In this first test station, the watches are simply placed in a shallow pan of tap water. Many may see this as a rather low hurdle for water resistance testing but it’s an important step that many manufacturers miss. A watch can actually become more water resistant in high depth/pressure situations but if a fault exists in the case or the seals, this low pressure test is far more likely to find it. If this step is passed, then the watches are placed in this chamber for high pressure testing.
In this third and final test, watches are placed on a heating device, and then a drop of cool tap water is placed on the top of the crystal. If condensation appears on the underside of the crystal, then it is known that the watch case is compromised in some way, and fails the test. All our Clone watches are fitted with Abyss Patented Deep-Sea Water Sealants and unique Abyss double core silicone ”O” Rings. These are made from neoprene silicon which is far more resistant to cracking, corrosion and aging that can be a problem with natural rubber. A screw in crown with Abyss rubber seal (O-ring) is fitted with a double seal that repels dust and water proof up to 300 meters. The brand emblems are carved out from one solid piece of stainless steel or solid gold, exactly like the real thing.
Dissecting the Helium Release Valve
In the first photo you can see the disassembled helium escape valve placed in order of how it fits together. On the left is the piston with its ABYSS “O” ring gasket. This moves out (i.e. to the left) if the pressure inside the case exceeds the tension of the spring holding it in place. Next is the body of the valve which screws into the watch case from the outside via the slots on its right. The flat portion on the left where the threads end accommodates a flat gasket. The spring rests inside the body of the valve, and this ensures that it is water resistant even without any pressure being exerted on the piston from the outside. Last is a flat metal washer. This is firmly friction fitted to the right hand side of the piston which is tapered in order to accommodate it. The washer also provides a base for the spring to rest on, thereby pulling the piston firmly to the right with enough pressure to squeeze the gasket thus ensuring the water resistance of the valve.
The second photo shows the piston and its ABYSS “O” ring gasket on the left. On the right is the body of the valve showing the recess that the piston and its gasket fit into. The flat part of the piston and the valve should be flush with the watch case when installed correctly. This is a simple and reliable over pressure relief valve that perform exactly as designed. The gaskets are superior longer lasting ABYSS type DEEP gaskets that are a patent combination of polymer neoprene and Fluorocarbon synthetic rubber which is far more resistant to cracking, corrosion and aging that can be a problem with natural rubber. Although slightly less flexible, it was developed to withstand high oxygen environments and other hostile chemicals and gases that will deteriorate natural rubber gaskets in short order.
Deep-sea divers not only needed solutions for water resistance at extreme depth, they also faced the danger of explosive decompression caused by helium penetrating the interior of the watch (divers breathed the mixture of oxygen and helium within their hyperbaric chamber after lengthy deep sea dives). To maintain a pressure identical to that underwater, the mixture in the hyperbaric chambers remained the same during the different phases of work and rest periods. This system was designed to eliminate the need to depressurize the chamber after each phase of work.
Before returning to free air, and depending on the depth attained, a period of depressurization was necessary to equalize the internal and external tension of the human organism. Though the process of depressurization is slow, the gas that accumulated inside the watch, having no means to escape fast enough, exploded the crystal off the watch, thereby risking injury to those inside the chamber and severely damaging an expensive watch. A solution came by installing a one-way pressure Helium release valve on the side of the watch case, at the nine o’clock position. The one-way valve will begin to equalize the pressure inside the watch when the difference between the exterior and interior of the watch exceeded 2.5 kg. per sq. cm.
