The He valve is useless and ineffective in water. It's only designed to release the excess He gas that the diver breathes when confined inside a diving bell or a bathyscape. The He gas is very microscopic in size and can get into the watch and blow out the crystal with excess pressure.

But you fellas are missing the whole point of this thread. My question is why have a watch which can take all the pressures of 4000 ft. when the person wearing it CANNOT!!!!!!
