50m water depth is about 75psi, 100m 150 psi. Not to be laughed at

That's probably about the same pressure it has to survive if you tread

Something that can survive 100m is going need it's seals put back in the

I've heard that you need to get a 200M watch if you want to press the
buttons when wet. But they are disposable items anyway these days,
unless you want a mechanical one as jewellery.
