Omega Seamaster 300M Titanium/Tantalum/Sedna Gold: What Is So Special?

One thing you will immediately notice (we did at least), is the shape of the helium escape valve. An extra crown at 10 o’clock was one of the characteristics of the Seamaster Diver 300M, and it is still there, but now in a conical shape. Now patented by Omega as new technology now permits it to be used under water. We are not sure how many of these helium escape valves are actually being used (based on the high number of sold Seamaster Diver 300M models we suspect it really is a low number), but at least it is cool to know it can be used professionally. Having a 4×4 car also means it probably can do more than you do with it, it is just fun to know your watch is at least able to be used 300 meters under water and that the helium escape valve is there to protect the crystal from popping off after your saturation dive.

Wait what? No where in my manual does it state not to use the He valve under water.... I guess in hindsite it makes sense that if the watch is exposed to high pressure He its not going to be in water....

The new manual does state not to use it under 50m. Which they are pimping as a feature of the new watches...

In the basel video I could have swore the gentleman was making a big deal about how it is now water proof when open. Maybe he meant the red indicator part of that feature was new.
