The history of helium escape valves is an interesting one, with humans once again proving it will never stop to conquer the unknown.

In the 1960s, Swiss watchmakers developed their “gas relief valve” for the Sea-Dweller, with the suggestion of U.S. Navy diver. Dive watch was an instrument, used side by side with depth and pressure gauges, to solve the issue that crystals explode off divers’ watches as they rose in decompression chambers due to the sum-up of helium gas in the watch, after extended stays inside the dry, pressurize habitus.

Helium Escape valve was a practical solution to this problem. This valve has a small spring that works when the change in pressure reaches a critical level. It releases the helium, hydrogen, and other gases used in the breathing gas that is trapped inside the watchcase, allows divers to go deeper with resilience.

Aquinus dive watches from the Immersius Collection are equipped with a helium valve and is waterproof up to 200 meters. The watches of the IMMERSIUS collection also allow you to read the decompression stop time using its unidirectional rotating bezel. Engraved with Swiss Super- LumiNova ensured long-lasting afterglow in the dark.
