Very insightful!I really struggle that anyone cares about this.
As long as the button presses, who cares?
If you're actually going down past 50m you're clearly in a submarine of some form, just unscrew the crown a bit and everything will be fine, any old rep can stand 10000 bar if the crown is open!
The recreational dive limit is 40m, you need to do extended training to exceed 20m, my OMF Speedmaster passes this test!
Great video by Harrison talking about this.
