A water resistant watch does not mean that you can go ahead and dip it in the water any time. There are predetermined levels of water resistance which is usually marked with the depth it was tested during manufacturing. But this does not mean that it can be used under those specified depths because a lot of other factors like pressure and chemical compositions can 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.
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.
External factors also affects the ability of watches in resisting liquid substances well. The sudden and rapid change of temperature and pressure is one of this. Another one is when the watch ages and seals like gaskets are starting to deteriorate and will not be able to have the same protection given 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.
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.
