Re: Omega Helium Relief vs Rolex nothing??

In Response To: Omega Helium Relief vs Rolex nothing?? ()

: Both the Omega SM Pro and Rolex submariner
: watches are rated at 300m water resistance.

: Why then does the Omega version require a
: helium relief valve, when the Rolex
: submariners I've seen have no such valve?
: Does this imply that Rolex watches are made
: with an even tighter fit so as not to let
: any He penetrate, thus implying that they
: are superior?

: I own an Omega SM Pro 2254.50.00.

: Thanks!

The Rolex Submariner does not have such a valve nor does a watch intended for "normal" free diving have any use for such a valve. The Rolex Sea Dweller does possess such a valve although it requires no user-intervention. You should know that helium escape valves, the way I understand it, are useful only to divers working in chambers on a mixture of compressed gas - namely helium and oxygen.
