BARRACUDA
Your Barracuda Diver is the watch for
professional and amateur divers, as
well as demanding sportsmen. The new
helium escape valve together with all the
protection systems, offer optimal security
and reliability. In order to ensure that your
watch remains watertight, we recommend
that you have it checked by an authorised
service center.
ALWAYS MUST BE CLOSED POSITION
Helium escape valve
When carrying out work at great depths, professional divers stay in a diving bell for several days, breathing a mixture of
gases containing a high proportion of helium. The pressure is gradually increased to reach the pressure at the working
depth. The divers, still inside the bell, are then lowered to the working site. They leave the bell to carry out their work.
Once their work is complete, they re-enter the bell, which is then raised to the surface. Pressure is then returned to
atmospheric levels and this is when the valve must be opened (only for deep-sea dives lasting several days) The helium
molecules diffuse and penetrate the material of the gas kets. The quantity is sufficient to push out the crystal during the
return to atmospheric pressure. To avoid this, the Barracuda Diving watch is equipped with a valve specially produced
by Quantum Watches.
CAUTION:
PLEASE PAY MORE ATTENTION TO KEEP CLOSED HELIUM ESCAPE VALVE, CHRONO BUTTONS AND SCREW
CROWN. OTHERWISE YOUR WATCH WILL LOSE IT’S WATERPROOF SPESIFICATION.
