How is the waterproof watch distinguished?

- May 10, 2019-

The waterproof function of the watch is usually divided into 30 meters, 50 meters, 100 meters, etc., and the waterproof apron at the main surface, back cover, crown and the like to achieve the corresponding waterproof standard. 30 meters (3ATM, 3 atmospheres) waterproof watch, can be used for daily grooming or rain, that is, water drops only splash on the surface without any water pressure on the watch. The 50m waterproof watch is suitable for swimming and general housework, and the 100m waterproof watch can be used for underwater work such as swimming and diving.

Generally, the waterproof watch should not be used in hot water baths, saunas, or environments with large temperature changes. Because the waterproof apron is affected by the temperature, it will expand and shrink, and the gap will accelerate and the aging will affect the waterproof function. Moreover, the water vapor molecules around it are relatively small, and it is easy to penetrate into the body, causing internal mechanical damage.

To keep the crown in the normal position, the threaded handle should be tightened. Do not adjust the crown in the water.

Even if it is a professional waterproof watch, its waterproof rubber ring should be replaced in a timely manner after one year, otherwise its waterproof performance will not be guaranteed. It is best to replace the waterproof parts at the same time each time the quartz watch is replaced to ensure good waterproof performance.
