Behind the Term
Water resistance is stated as a depth (BAR, ATM, meters or feet). It represents the fact that this model was tested in a laboratory to withstand the static pressure for a short period of time, only at the stated depth. Remember that when you actually use the watch, you are putting it under more water pressure than the static pressure. For example, if you dive into the water, the impact on the watch is far greater when it hits the water surface than the pressure when the watch is resting on your wrist underneath the water.
Levels of Resistance
Not marked. If your watch is not marked water resistant, you should take it off before you wash your hands, take a shower or wash the dishes.
If the watch is marked water resistant, but no specific numbers are given, it can withstand an accidental splash experienced when you run in the rain from your car to your house. It is not safe to wear it when washing your hands or showering.
If it is labeled water to 3 ATM, 30 meters and 100 feet, the watch is suitable for accidental
