Water Resistant is a common mark stamped on the back of wrist watches to indicate how well a watch is sealed against the ingress of water. It is usually accompanied by an indication of the static test pressure that a sample of newly manufactured watches were exposed to in a leakage test.
Waterproof (or water-resistant) describes objects unaffected by water or resisting water passage, or which are covered with a material that resists or does not allow water passage. In horology, the waterproofness of a watch is defined by its resistance under pressure.
Water resistance is measured by the amount of water, in mm, which can be suspended above the fabric before water seeps through. [ citation needed ] Breathability or moisture vapor transmission rate is measured by the rate at which water vapor passes through, in grams of water vapour per square meter of fabric per 24-hour period (g/m 2 /d), [ 2 ...
Water resistance may refer to: The WR mark on a wristwatch indicating its ability to withstand exposure to water; The IP code on a mechanical or electrical enclosure indicating its ability to resist the ingress of water; Wet strength, a measure of the strength of paper when wet

A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m (660 to 980 ft), though modern technology ...
Waterproofing conducted on the exterior of a freeway tunnel. Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions.
Desiccation tolerance refers to the ability of an organism to withstand or endure extreme dryness, or drought-like conditions.Plants and animals living in arid or periodically arid environments such as temporary streams or ponds may face the challenge of desiccation, therefore physiological or behavioral adaptations to withstand these periods are necessary to ensure survival.
