Not having ever gone diving, I wonder what dive computers use? I would bet they ain't screw-down.
That's another of my areas of bafflement - chrono watches with screw down crowns but with unsecured pushers that aren't supposed to be used underwater! Some are disturbingly easy to operate by accident. Talk about style & fashion leading function! I guess it just demonstrates that having a screw down crown, whilst having a function in theory, actually adds very little in practice.
