That is fantastic. Seems a little ironic the deepest diving watch doesn’t have the HEV. Or does it have one flush like a Pelagos?

Great buy.

The reason for no HEV.

There wasn’t even a need for a helium escape valve. How is this possible? Well, by using a sapphire crystal created via the “Edge-Defined Film-fed Growth” (EFG) process.



A unique kind of sapphire crystal produced only by Omega, EFG ensures the resulting sapphire crystal is deprived of all imperfections that could cause fragility in the material when exposed to extreme pressures. The sapphire crystal is then formed into a shape that guarantees extreme pressure resistance and allows the Omega Seamaster Planet Ocean Ultra Deep to be a tool watch fit for saturation diving.



And so, due to these technical innovations, a helium escape valve is not necessary. Plus, the anti-reflective coating is applied to both sides of the crystal, ensuring the watch is readable, whatever the conditions.

So how do non Omega watches which are depth rated to 600m get around not having a helium escape valve?

I think my oldest watch in my collection. I would guess it's from the late 90s.

Because no one takes them to 600m to find out if they need the escape valve or not biggrin

Disclaimer - the deepest my Seamaster has been is 3m snorkelling.

Very pleasantly surprised by my latest budget purchase. Seems to be nicely finished with a lovely retro vibe at 38mm.



The view from the rear is very pleasant too !
