If your watch is water resistant, the type of resistance should be indicated on its lid.

Por example: if the lid on your watch says 3 ATM, it means that your watch is resistant to 3 atmospheres of pressure, or submersible for up to 30 meters.

Every water resistant watch is submited to lab testing, where specialized equipment is used to apply the equivalent atmospheric pressure.

However, keep in mind that the type of activities or blows sustained if the watch is submerged, can affect its resistance to water, as well the watch’s lifespan, given that the parts may be weared.
