About Water-resistant Watches
Water Resistant Watches are sealed to resist some pressure.

Water resistance is tested in measurements of atmosphere (ATM). Each ATM denotes 10 meters of static water pressure. This isn’t the depth to which a watch will also be worn. Many watch cases will list the basic measurement of 1 ATM as “water-resistant.” These watches will withstand small splashes of water but must not be worn even as washing the hands or submerging the hands in water.

Needless to say, 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 throughout a 50-metre static test. Subsequently the number of metres shown on the watch does not indicate the depth that the watch will also be taken to.

Here is a general guide
50M = 5ATM = Shower Proof – it’s ok to get it wet a bit.
100M = 10ATM = Extended Water Exposure good for swimming or snorkeling.
200M = 20ATM = Pressure Resistant made for Scuba and Skin Diving.
