Diving and watches go hand in hand. For divers, the scuba diving watch is an essential accessory.

As the descent progresses, the pressure becomes more and more important. Professional or seasoned divers, who go to the depths of the ocean, are equipped with diving belts or have underwater habitats. For the duration of their excursion, those equipments allow them to breathe a special air. It is a mixture of helium, hydrogen and oxygen. This mixture will be introduced into the human vessels, which will help divers tolerate the pressure difference between the depths and their bodies. During the ascent, the divers will go through decompression stops to eliminate helium gas in the human tissues.

 

Helium particles are known to be the finest particles in the world. They manage to slip and get stuck in the case of watches yet waterproof. This causes a pressure difference between the watch case and the outside environment. During ascent, the increasing pressure difference can blow up the glass of the watch.

 

The system of helium valve on dive watch has been developed to protect their diver watches from damage. Moreover, the mechanics of this system is relatively simple. The helium escape valve, when activated, will allow the gaseous mixture present in the watch to escape when the pressure in the watch becomes stronger.

 

 

RESERVOIR Swiss made automatic dive watches from the HYDROSPHERE collection are equipped with a helium valve and is waterproof up to 250 meters. The design of the watch’s dial is inspired by diving manometers. The helium valve watches of the HYDROSPHERE collection also allow you to read the decompression stop time using its unidirectional rotating bezel. These 3 watches in this collection are emblems of the brand with the retrograde minute, the jumping hour and the power reserve.
