　　People who like to swim or dive with their watches usually have a waterproof performance test for their watches once a year in order to feel at ease. This test can only be carried out after the relevant parts of the watch are updated, such as battery replacement and maintenance.

　　All excellent watchmakers have professional instruments, which can carry out stress tests for watches at a reasonable depth (that is, the depth often visited by swimmers and divers). This instrument will not exert strong pressure on the cover. If it is found that the watch is not completely encrypted, it will not let other foreign objects soak in the watch. This test can only be carried out in a vacuum environment. Once the sensor placed on the surface detects any slight deviation, it will show that air is leaking from the watch case through the cover. If you can pass the test that lasts for several minutes, the watch will be waterproof.

　　In order to ensure that watches can cope with the great pressure faced by professional divers when working in the deep sea, watches must be tested by more stringent testing tools. This kind of test is risky, because once it is poorly sealed, water will enter the meter. Moreover, this test is more time-consuming than vacuum pressurization test. The method is to put the watch into the water injection instrument and then pressurize it. When the pressure is released, heat the watch and place a drop of water on the watch mirror. If water vapor condenses on the inside of the watch mirror, it means that the waterproof apron is leaking and new waterproof accessories must be replaced.

　　In the daily movement maintenance, every watch must pass the air pressure test, and some authorized service centers will add the real water test. You can use a watch that has passed both the air pressure test and the real water test with confidence.
