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 other factor will be the crown, a dial used in adjusting time in watches which can be found at its case edge. Regular and constant use will cause its gasket to have a slight change enabling the liquid substance to get inside through its stem hole. Not pushing the crown properly and tightly will also cause this. Screw down crowns usually are used for resistant watches instead because of its gasket which seals the stem hole if tightened.
Last is the gasket made out of nylon or rubber and creates watertight seals in the case back and crown together with the case. Chronograph pushers of most chronographs have gaskets too. Although, the gasket may need to be replaced when it starts to deteriorate after a while.
External factors affects its ability of the wristwatch to resist liquids as well. These include the temperature and pressure specially its rapid and sudden change. Another is when the watches age, the gaskets and other seals start to deteriorate and unable to keep the same level of protection anymore.
There are two ways to test the resistance of watches and these are dry test and wet test. The dry test is performed by placing the wristwatch in a sealed container where air pressure is gradually raised. If the casing slightly changes its shape then it had failed the test.
Wet test is done by putting the wristwatch inside a container filled with half air and half liquid. Air pressure is steadily raised while the watch is outside the liquid and then it will be slowly submerged after. They will then release the air pressure slowly and if bubbles do come out from it then it 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.
