Water resistant watches do not mean that it can be dipped in the water any time. There are certain conditions to be considered including the levels of resistance indicated stating the depth tested for it during manufacturing. This does not also mean that it is usable under those depths specified because different factors such as pressure and the surrounding chemical compositions may affect it.
Overtime, the resistance level changes with regular use and other external factor affecting it. You may want a watch water resistance testing Cambridge to know if your watch is still resistant. Here are some information and tips from the watchmakers and experts from Cambridge, MA.
There are three main factors that affect the water resistance of watches. One of these is its case back and how it is affixed into it. It can be affixed with these three ways, snap on, screws or with screw in. Snap on has the least level of resistance with a depth of thirty meters while screws provide up to a hundred meters and the screw in gives maximum possible level at a hundred meters or more.
The next factor is the crown, the dial that is used in adjusting time located at the edge of the case of watches. Its regular use will cause the gasket to change its shape slightly or not properly pushed in permitting liquid substances to be able to penetrate the inside via its stem hole. Resistant watches usually use screw down crowns because of the gasket it has that seals the stem hole when tightened.
The last one is the gasket which is made of rubber or nylon and forms watertight seals between the case back, crown and case. The chronograph pushers of chronographs will have gaskets as well. Gaskets will deteriorate over time which affects its role and must be replaced when possible.
There are external factors affecting the ability of wristwatches to resist liquid substances too. Rapid and sudden changes in pressure and temperature are one of them. Another is the seals of watches like gaskets start to deteriorate when it ages and will be unable to provide the same kind of protection anymore.
The water resistance can be tested in two ways, either by dry test or wet test. The dry test puts the wristwatch inside a sealed container and the air pressure is increased gradually. It has failed the test if the casing changes slightly.
The other method is wet test where the wristwatch is placed inside a container with half water and air filled in it. The air pressure is raised while the timepiece is out of the liquid then slowly submerges it in. When it is fully submerged then the air pressure is decreased slowly and if bubbles come out of it then it had failed the test.
Make sure you have your watches tested at least once in every year to make sure it can still resist liquid substances. The rating of fifty meters and below usually mean that it can only take splashes and cannot be fully submerged. Ratings of a hundred meters and above means that it is safe to take a shower or go swimming when wearing it. Take note of these things.
