It's an old myth about the movement in water. You would need to move your arm at about 32mph to add 1atm of pressure. If your watch tests out at 3atm you can swim in it. However if it says 3atm on the back then don't risk it as it may not be that water resistant and there is little margin for error. Like this

TJ as you have tested the watches can you give some sort of list that shows at what pressure you have tested your reps. On some sites I do see that some offer to put new seals etc in the watch and test is to 5 bars. What does a standard not modified rep withstand as for pressure.

Looks like the links are all working again.
