My Barracuda has a manual Helium release valve (HRV), and some of the Sea Devils have them, too. My question is, is this separate valve really necessary? Wouldn't unscrewing the crown have the same effect (release any pressure inside the case)? Someone correct me if I'm wrong.
Note, this question is not in reference to an automatic HRV as on the 1km and planned for the Megalodon. Just talking about unscrewing the crown being the equivalent of opening a manual HRV.
