Did you just happen to have that up your sleeve from the last time we went around on this? Must remember that!
Here's a good explanation for dive bells with links from Wiki...
A diving bell is a rigid chamber used to transport divers to depth in the ocean. The most common types are the wet bell and the closed bell.
The wet bell is a cable-suspended chamber, open at the bottom like a moon pool structure, that is lowered underwater to operate as a base or a means of transport for a small number of divers. The pressure of the water keeps the air trapped inside the bell. They were the first type of diving chamber. Unlike a submarine the diving bell is not designed to move under the control of its occupants, nor to operate independently of its tether.
The closed bell is a sealed chamber, which may be used for mixed gas bounce diving and for saturation diving. This form of bell locks on and off the chamber where the divers live, by way of a closed door sealing the divers in at pressure. Once on the surface, the bell is mated with the chamber system and the space in between is pressurized to enable to divers to make a seal and transfer through to the chamber which is at the same pressure. In saturation diving the bell is merely the ride to and from the job, and the chamber is the living quarters. If the dive is relatively short (a bounce dive), decompression can be done in the bell in exactly the same way it would be done in the chamber.
I guess its only to be expect of Seamasters now. Although i do like the look i must admit.

A simple 'like' wasn't enough, that is pure unadulterated genius. I tip my hat to you.Well I need my helium valve. I use it all the time.
I agree with you!
But I think it makes the forum more interactive rather than being just a big archive were people spend their times in searching for an answer.
Not that I'm reluctant to read the forum, I do search for a thread from time to time. It is just that sometimes, some threads are too big that it takes you an hour to read without finding what you are searching for!
Thank you for the link!
Rolex does this with a one-way flush valve on the case that automatically triggers at a certain pressure differential.
IIRC Omega has a one-way flush valve that operates in a similar way (but not exactly due to patents), but they have the additional crown over it that needs to be unscrewed to let that valve work in the first place. Yes, it's basically two caps on one toothpaste tube. That's why it gets so much grief.

Helium doesn't, can't, won't get into any watch while diving.
Helium can't enter the watch while in the water.
The He valve is only of any use for a very small number of commercial deep sea divers that dive so deep and for so long that they breathe special gas mixtures containing helium and have to spend hours or days in decompression chambers breathing the same gas mix.
If you spend lots of time in a decompression chamber perhaps you could do with a He valve on your watch but it is 100% useless for everyone else.
