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.

The test pressure can be indicated either directly in units of pressure such as baratmospheresor more commonly as an equivalent water depth in metres in the United States sometimes also in feet.An indication of the test pressure in terms of water depth does not mean a water-resistant watch was designed for repeated long-term use in such water depths.

For example, a watch marked 30 metres water resistant cannot be expected to withstand activity for longer time periods in a swimming pool, let alone continue to function at 30 metres under water.This is because the test is conducted only once using static pressure on a sample of newly manufactured watches.

As meters 50 watch smart wr a small sample is tested there is likelihood that any individual watch is not water resistant to the certified depth or even at all.The test for qualifying a diving watch for repeated usage in a given depth includes safety margins to take factors into account like aging of the seals, the meters 50 watch smart wr of water and seawaterrapidly changing water pressure and temperature, as well as dynamic mechanical stresses encountered by a watch.

Also every diving watch has to be tested for water resistance or water-tightness and resistance at a water overpressure as it is officially defined.The International Organization for Standardization issued a standard for water-resistant watches which also prohibits the term waterproof to be used with watches, which many countries have adopted.

This standard was introduced in as the ISO They may be used under conditions where water pressure and temperature vary; German Industrial Norm DIN is an equivalent standard.However, whether they bear an additional indication of overpressure or not, they are not intended for submarine diving.

The ISO standard specifies a detailed testing procedure for each mark that defines not only pressures but also test duration, water temperature, and other parameters.Skip-lot sampling procedures concerning procedures regarding lot sampling testing come into play, since not every single watch has to be tested for ISO approval.

Regarding pressure ISO defines: This has since be replaced by the ISO In practice, the survivability of the watch will depend not only on the water depth, but also on the age of the sealing material, past damage, temperature, and additional mechanical stresses.

This standard was introduced in ISO defines such watches as: ISO testing of the water resistance or water-tightness and resistance at a water overpressure as it is officially defined is fundamentally different from non-dive watches, because every single watch has to be tested.

Testing diving watches for ISO compliance is voluntary and involves costs, so not every manufacturer present their watches for certification according to this standard.Movement induced dynamic pressure increase is sometimes the subject of urban myths and marketing arguments for diver's watches with high water resistance ratings.

In this case, the watch is subjected to the pressure of the gas mixture and its functioning can be disturbed.Consequently, it is recommended to subject the watch to a special extra test.

ISO defines a diver's watch for mixed-gas diving as: The following specific additional requirements for testing of diver's watches for mixed-gas diving are provided by ISO Most manufacturers recommend divers to have their diving watch pressure tested by an authorized service and repair facility annually or every two to three years and have the seals replaced.

These vagueries have since been superseded by ISO From Wikipedia, the free encyclopedia.

Retrieved 15 March It clarifies the terms used, defines the criteria to be met by the product and specifies the marking which may appear on the product.In order to calculate the dynamic pressure caused by a fast underwater swimming movement of a diver the following formula can be applied: ISO standards by standard number.
