3 atm. / 30 meters (also known as water resistant water-protected / watersealed):
these watches are resistant to rain and splashing water.

5 atm. / 50 meters (also known as proof shower / waterproof):
these watches are appropriate for showering or swimming, be aware off large temperature differences.
However, they are unfit for snorkelling or diving with compressed air.

10 atm. / 100 meters (also known as waterproof):
these watches are suitable for most forms of water sports such as swimming, sailing and snorkelling in shallow water. However, they are unfit for jumping or diving with air. Be aware off large temperature differences.

20 atm. / 200 meters or more (also known as waterproof 20 atm. / Diving proof):
This watch is suitable for all types of water sports and diving.

Temperature Differences
Temperature differences are an insidious factor that causes many leaks by supposedly waterproof watches. A "watertight" case that is suitable for daily showers. Example: Case can completely flooding with water when you go on holiday to swim. When you shower with the watch, the temperature of the water is +/- equal to that of the watchcase. When this watch, however warmed up in a nice tropical sun, the temperature in the case heat up to 50 ° C or even warmer. If the watch suddenly is in contact with water with a temperature of 20 ° C, the watchcase gets a huge blow by the relatively high temperature. A case that is not specifically constructed for such circumstances, will leak and will run full off water.

Watertight guarantee
Gaskets wear alone by the use of buttons and switches that sealing them, and also by opening and closing the watchcase, for example replacing the battery. Gaskets also can dry out in time or digest, the latter including by acids in perspiration and by exposure to chlorine and seawater. Even soap and shampoos which are used when showering, these are degreasers and ensure a rapid aging of the gaskets.
It is often that a crown or pusher of a watch is bumping into something, often without being aware of that. If the crown or pusher is hit (which is not always visible) can lead to leakage. For these reasons, the tightness of watches can never be guaranteed!

Even in well-sealed, waterproof watch cases, it is possible that condensation occurs on the inside of the glass. This does not necessarily mean that the watch is 'leak'. Condensation can also arise when the watch suddenly cools down. For example, when a watch is worn during skiing under a jacket, the case can be pretty hot. If the watch then suddenly get exposed to a cold environment, then the glass cools faster than the metal case.
The moisture that is in the air in the watchcase is, can condense and a slight haze forms on the inside of the glass. Once again the glass temperature is reached this will disappear.
