If you are about the buy the diver’s watches for yourself then you should know at least one thing, and that is the standards that are set for the diver’s watches are not only strict but at the same time, they are quite specific in nature as well. If you are planning to buy the diver’s watch then you should have one thing in mind and that is you should follow these both strict and specific requirements. There are some watches although, which do not have any labels such as diver’s watch. Remember these kinds of watches are really not suitable for various kinds of water sports such as scuba diving. If you are someone who love underwater sports and love the water more than anything else then you should definitely go for those watches that are labeled as diver’s watch. Before you have a look at the specification of these watches it is better that you have a look at the history of these watches first; it would help you to know a lot about these watches.

The history of diver’s watches to the year 1600
If you think that the diver’s watches are quite new then you are wrong. Almost during the year 1600, the water resistant watches came into existence. In the year 1800, the people witnessed not only water resistant watches but also at the same time dust resistant watches as well. The watch, at the turn of the century, became popular among the uniformed mass, which includes the military people, and especially to those who were working for the navy. Slowly, it became a watch loved mostly by the scuba divers. It was designed in such a way that it allowed the divers to rise at the surface at a pace, thus helping the divers a lot because they would not have to suffer from any kind of sickness related to decompression. The ISO certifications for these watches were introduced in the year 1966.
The reason behind going for the ISO standards in case of the diver’s wrist watches
It can be said that the ISO standards are set for the diver’s watch so that they could facilitate the trade that they are carrying on across the national borders. If these standards are there with the watches then it would allow the people to know that these watches are specially design for the purpose of scuba diving. Well, pretty cool, what say? In the market you may find watches similar to that of the diver’s watches, but without any kind of ISO certification. You could surely invest your money for these watches but do remember one thing, and that is this watches won’t guarantee you the support that you would have from the certified watches, during the time of having a diving experience. The ISO certified standards that are there around the world for the diver’s watches include the ISO 6425 standards. So, what are the basic standards of a diver’s watch? Now, this may be the obvious question that you people are having in your mind.
What are included in the basic standards of ISO certification?
The manufactures, if they are manufacturing ISO certified diver’s watches they should keep certain things in their mind, which include the following things:
The watch should function deep underwater
It is important that the certified diver’s watch should carry on with their functions at a depth of around 100 meters or below.
Reliable even underwater
The watch should ensure that it is in a state of working condition even at a foot of water for around 50 hours, the temperature would be approximately the room temperature that is there.
It is a very interesting test through which the diver’s watches have to go through. In this particular test the watch will be first heated at a temperature of around 40 degree Celsius, and then a drop of water is place on it. If the water is wiped away then you pass the test but if the condensation remains then you get failed in this particular test. Thus, your watch does not get certified as the diver’s watch.
Testing the pressure
It helps in checking the amount pressure the watch could handle. Therefore, the watch is exposed to a pressure of around 125 percent. It is so because it is the percentage that most of the diver’s watch market, and state that it can withstand this amount of pressure in the water. The test does not end here. There is still more left. What? The watches are also exposed to a 5N of force, which is perpendicular to the watch’s crown and the button.
The diver’s watch has to deal with the over pressure for around 2 hours, in order to receive the ISO certification. After that the pressure is reduced. If you are thinking for how long then it is to tell you that it is reduced for an hour. Now, what is being done? The watch is being dried. If there isn’t any sign of condensation and water have not leaked inside the watch then you have passed the test.
Testing Thermal Shock Resistance
This is a very unique test, where diver’s watches are immersed several amount of time and that too at various different temperature. You must be thinking why this weird test is being carried out? The answer is, very simple in order to withstand water intrusion and condensation process.
