Water resistance up to 30 meters deep (3 BAR ≈ 3 ATM)

These watches can withstand a pressure of 3 ATM, which is equivalent to 30 meters under water without movement (static pressure). What it really means is that the watch is impervious to rain and splashes. It doesn’t really mean that your watch is waterproof to 30 meters.
