Diving is not only the need to address water-resistance in extreme depth. They also faced the danger of explosion caused by decompression helium penetrate internal watches, and they inhaled a mixture of oxygen and helium in its hyperbaric chamber.

In order to maintain the same underwater pressure, the mixture remained unchanged in the high-pressure chamber of commerce in different stages of work and rest time. The purpose of this system is to eliminate the need for decompression chambers of commerce in each stage.

And then return to the free air, and in accordance with the depth of reach decompression time is necessary GammonEmpire external and internal tensions of human organs.

Although the decompression process is slow, the gas accumulated inside the watch, there is no means to escape fast enough, the explosion of the crystal, causing serious harm to those within the Office.

This issue is resolved valve placed in the 9 o’clock position, to allow the helium to escape under the pressure bit by bit to take the atmospheric pressure.
