AN OBSESSION WITH PERFECTION
THE HELIUM VALVE
Before going back out into the open air, a professional diver who returns to the surface after a deep dive must spend time in a decompression chamber, where he breathes a gas mixture containing helium.
In the chamber, the helium, an extremely light, volatile gas, infiltrates everywhere, also penetrating the watch. It escapes from the watch at a slower rate than the reduction of pressure in the chamber, with the result that the pressure of the helium imprisoned inside the watch is so great that irreparable damage could occur.
After studying these parameters, Rolex engineers created a helium valve fitted with a spring: it opens when the difference in pressure between the inside and outside of the watch reaches 3 to 5 bars, allowing the helium to escape and protecting the watch.
