For some reason this makes me recall a person on watchuseek that attached their PO to a line and submerged it to whatever its max rating was. Have all PO’s been 600m? This was many years ago.

But on the original topic, I wouldnt be surprised if someone has actually made use of an HE valve. Not out of necessity, but just experimenting. I’m clueless about diving, but wouldn’t anyone performing something like a saturation dive be wearing something like a dive computer? Out of necessity

The only time I’ve had to replace a HE valve, was when having service and the HE valve leaked during water depth test, at 200m started showing air bubbles.

Had the watch been in a deep sat environment?

of course I saturation dive daily, the water test was done by a qualified watchmaker, and that is what was conveyed and charged to me when I picked up the watch. There is the heated air test to depths of 300 or so meters and the vaunted Witschi Proofmaster Pro tests.
So…your point is ?

I doubt many people have ever used it.
I go further and say that many who wear a dive watch do not dive and some don’t even know the intended purpose/function of the bezel.

I understand, and agree with your assumption that many do not use it. I myself while having this watch have only unscrewed the HE crown out of curiosity to see it parts….once, never intending to make use of it. I have to presume, simply based on physics that the rubber/polymer seals/gaskets deteriorate over time and that was the cause of my HE valve being replaced.
The valve is used to release pressure that is created in any deep dive, divers and scientists have stated that pressure that is not venter could cause the watch to explode…in more practical parlance … The sapphire crystal to pop out !

HE valve being replaced.
Nope, Omega replaces crowns and HEV's by default at every service.

Thank you for invaluable information…I’ll mention it to my watchmaker I’m sure he’ll be interested.
Go find some else to troll

Correct. But that’s Omega, and not necessarily the way all watchmakers work. Depending on the type (era) of the valve, I’ll just replace the seals rather than the whole valve.

The newer and current valves are designed to be changed as a unit, which is incredibly wasteful considering it’s just two O-rings that need replacing.

Never, because I have never done any saturation diving. Deep on mixed gases is one thing but diving from a bell is another animal. Most of my wreck work is at 150 feet or less, but typically much much less than that.

There is technology to make watches impermeable to helium at pressure anyway (Seiko pioneered it) so if you're going to have an escape valve, it should at least be automatic like the one on my Stowa Prodiver which is my go to watch for diving.
