Why a 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 gaskets. The quantity is sufficient to push out the crystal during the return to  atmospheric  pressure. To  avoid  this,  the  Seamaster  Professional Diver is equipped with a valve specially developed by OMEGA.

In SKYFALL (2012) James Bond, portrayed by Daniel Craig, wears two OMEGAs. One is a Seamaster Planet Ocean with a 42 mm stainless steel case and a matt black unidirectional divers' bezel. It is presented on a stainless steel bracelet. It is equipped with an OMEGA Co-Axial calibre 8500.Like all Planet Ocean watches, it is water resistant to 60 bar (600 metres / 2000 feet). The other is a Seamaster Aqua Terra with a 38.5 mm stainless steel case on a matching bracelet. It has a distinctive blue dial with the Teak Pattern design that defines the watches in the Aqua Terra collection. It is water resistant to 15 bar (150 metres / 500 feet). The entire history of James Bond's relationship with OMEGA is available on the OMEGA AND BOND page.
