I may be silly, but by looking at the construction of the crown with just a flat o-ring and no gasket inside the tube and press fit by the CG lever, unlike the screw downs in Rollies, can they really dive down deep into the sea? I do mean the gens. Or do they have different crown/tube/CG constructions than the reps?

To be honest, I am not dare to touch the water with this built.

The gens shut tightly and have a minimum if two gaskets between the crown and the movement. Yes they are waterproof. Most reps have two gaskets as well. But whether rep or gen, proper greasing and checking the seals is critical.
