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.
