Water Resistance
Most watches on the market are water resistant. A watch should be marked "water resist" to confirm its level of resistance to moisture, as there are several degrees of resistance.
Water Resistance: measure of the degree to which a watch will resist the intrusion of moisture. The following chart describes the amount of water measured in feet or meters that each watch can resist.

A measure of the durability of a watch when put into contact with water. Water resistance is measured in atmosphers (ATM), where one ATM is equal to 10 meters of water pressure or 1 bar ...
Watch Water Resistance: An Explanation
To meet the demands of today's consumer, water resistance is a watch feature that many consider a requirement.
Water Resistance.
Atmospheres (ATM) are the standard that water-resistant watches are measured against. One atmosphere is the air pressure at sea level and is equivalent to 10m of water.
A crown which aids water resistance by sealing the crown against the case. The seal is achieved by the matching of a threaded pipe on the case with the crown's internal threads and gasketing while twisting the crown to lock it into place.
They ensure water resistance. O-rings may also be used on the winding stems of watches and in the winding crowns to protect against the water and dust penetration. The o-ring is normally made from a rubber or plastic compound.

The feature of a watch that denies water and moisture from penetrating inside its case. No watch is completely waterproof, but several can withstand rain and splashing. Water resistance is measured in ATMs (atmospheric pressure).
"water-resistant" on its case back can handle light moisture, such as a rainstorm or sink splashes, but should not be worn swimming or diving. If the watch can be submerged in water, it must state at what depth it maintains water resistance.
Its high weight-to-volume ratio allows it to counterbalance the heeling effect of wind on the sails while at the same time occupying a small volume and thus offering the least underwater resistance.
