Helium ventil

[willy]

I do not think it matters very much to 99% of divers if the watch comes with a Helium valve or not . So we could conclude that most Helium valves are a waste of space , and are of no pratical use at all . But i am sure that it costs more to build it onto the watch .
Many watches are made with all sorts of dibs and dabs on them , that have no real use what so ever . But they can be used as a sales argument Willy
