Water resistance is tested in measurements of atmosphere (ATM). Each ATM denotes 10 meters of static water pressure. This is not the depth to which a watch can be worn. Remember, water resistance is tested under static conditions. Wearing a watch which is 50 metres water resistant to water will expose the watch to a much greater pressure than during a 50-metre static test. Therefore the number of metres shown on the watch does not indicate the depth that the watch can be taken to.
