Exploding...

 

..not imploding, or at least blowing off the crystal or caseback or crown caused by the unreleased pressure.  Which is why Omega dive watches have the helium valve they do.  Was always surprised that the regular Submariner does not have a He escape valve.  SDDS, Comex and whatnot do, smart.

Question: do ALL diver's watches (Blancpain FF, etc.) have a He escape valve or a similar pressure release system?  Research time...
