Waterproof watches of this category are carried exclusively as safety clocks to the time alignment beside the deepmeter watches!

Comment:
The helium valve is especially for occupation diver interesting, who are held also in air environment on pressure. Helium atoms are so little that they can penetrate through sealings into the clock and can construct an interior pressure. This is further not tragically - if all helium atoms could leave in outside pressure reduction quickly enough the clock.  For this case we add this special valve, which lets the helium-atoms again outward, otherwise it would come to an explosion of the clock!
