How to use the helium escape valve? (fig. 2)
In its normal position (fig. 2.1), the
OMEGA
helium escape valve
is perfectly watertight thanks to the gaskets (B), but it is not func-
tional, since it is screwed down.
During the decompression phase, unscrew the crown of the valve in
order to release the mechanism (fig. 2.2). The valve is now water-
tight from the outside. As the interior pressure becomes greater than
the exterior pressure, it pushes the gasket A out of its seating, thus
releasing the gas (fig. 2.3). once the pressure is equalised, gasket A
returns to its original position, pushed by the spring C (fig. 2.2).
This operation is automatically repeated several times during the
decompression phase. once atmospheric pressure is reached, screw
down the crown of the valve (fig. 2.1).
Note:
even if the valve is unscrewed, and we recommend that
the valve remains screwed down whenever the watch is immersed
in water, the watch is still water resistant to 50 metres. However,
complete water resistance is guaranteed by gasket (B) when the
valve is screwed down.
