That gets into a whole other mess and the somewhat irrational reason that I'm curious about this in the first place. I always hear conflicting things in regards to water resitance. I hear that 50 meters isnt enough even for wading through a shallow stream, and then from others that 50m is enough to swim with. If it was 10 meters it would put it more in the comfort zone of being able to comfortably tackle basically anything like the occasional swim.
In any case this is all irrational because I never swim with mine anyway. But I have the irrational fear that one day, ill be forced to dive off a waterfall indiana jones style (or something to that end) and my watch wont survive thus leading to NAZI's taking over the world...
Like I said, irrational.
