You need to be able to identify what water resistance watch you are looking for, and also have a good grasp of the terminology being used to describe it.

Deep Blue World Timer quartz Chronograph GMT Watch is one example. It has what a diver would want – a unidirectional rotating watch with a scale. The screw-down crown at 3 :00 has two function pushers that allow you to control the chronograph movement. The most important thing is the words: Water resistance: 50 ATM – 500m – 1,650ft These are the numbers that you will need to see in order to be certain that the watch is water resistant. It is built to withstand the required depth.

Although you must include the words “water resistant” in every product description, it is also important to mention them on the back of the watch or the dial. Although you might be familiar with the term “waterproof,” there is no such thing. Water is the current term.

The Meaning Behind the Term

Water resistance can be described as a depth in meters, feet, BAR, ATM or meters. This indicates that the model has been tested at the specified depth in a laboratory to resist static pressure. When you use the watch, it is subject to more water pressure that the static pressure. If you take a dive in the water, the pressure on the watch will be greater than if it is sitting on your wrist under the water.

Different levels of resistance

Not marked. You should remove your watch if it is not water-resistant.

The watch may be water-resistant, but not specific numbers, if it is. This means that it will withstand a splash from rainwater when it falls on your car or your home. It is not recommended to use it while showering or washing your hands.

The watch can be used for accidental splashes if it is water-resistant to 3 ATM, 30 m, and 100 ft. It can be worn to wash it, but not for swimming.

It can be worn while swimming if it is water-marked up to 5 ATM, 50m, and 165ft. However, it cannot be worn when you dive in a pool, snorkeling, or engage in other water sports.

You can swim or snorkel with it if it is water resistant to at least 10 ATM, 100m and 330ft. It is not suitable for sub-water or high-board diving.

It can withstand high-impact water sports, such as scuba diving, at depths that do not require helium gas, if it is marked water level 20 ATM, 200m, and 660ft

The Standard

International Organization for Standardization established the water resistance standard in 1990. This is the same organization that banned waterproof watches from being described. This standard outlines the testing procedures for each mark. It specifies the test procedure for each mark, including water temperature, pressure, and time required to complete tests.

Water resistance testing consists of the following:

The watch’s resistance to water immersion at 10 cm depth for an hour

Resistance of watch’s parts during submersion in water of 10 cm with a force 5 N for 10 min

Condensation test: Place the watch on a heated plate at 40degC or 45degC for 10 to 20 minutes. After that, testers place a drop water on the watch’s glass and check for condensation after one minute.

You can test the watch’s resistance to temperature changes by submerging it in water for 5 minutes at various temperatures.

You can test for water resistance by submerging the watch in a pressure vessel and exposing it to the rated pressure within one minute.

Resistance to overpressure: expose the watch to a pressure of 2 bar. The watch should not show an excess of 50 ug/min.

Tips

Even waterproof watches are not made for extended active water use.

Water-based chemicals can cause damage to the watch seal. The seal can also be affected by perfumes and aerosol sprays. To avoid contact, take off your watch.

Every two years, have your watch’s water resistance tested by a qualified watchmaker. To maintain your watch’s water resistance, gaskets might need to be changed.

Make sure that the buttons and crown are in their original positions before you go into the water. Watches that are not secured by the screw-down buttons will lose their water resistance when they touch the water.

Water resistance is also affected by the depth of water, the age and condition of the sealing material, as well as the watch’s past damage. The temperature.
