Recently, some friends reported that they bought waterproof watches and went swimming, so they suspected that the seller had deceived him, so they went to Shenzhen Watch Factory to find out about the situation. Today, Shenzhen Watch Factory will explain why many waterproof watches can not swim with water?

Because many waterproof watches are not swimming and diving watches, although it uses sealing measures to prevent water splashing and the invasion of daily sweat, but can not be immersed in water.
Generally, the waterproof depth marked by meters or atmospheric pressure on a waterproof watch is the theoretical waterproof depth when the waterproof test is carried out in the laboratory. When the watch manufacturer tests, both the watch and the water are in a constant temperature and static state. But in real life, this kind of constant temperature and static does not exist. Another method is according to the waterproof degree of the watch, the waterproof degree of the watch is divided into 30 m, 50 m, 100 m, 300 m, 500 m waterproof. Understand the following chart and you will know what level of waterproof watch you can take to swim.
Wearing a watch in the water will greatly increase the water pressure on the watch. Therefore, it is better not to wear a waterproof watch to swim or take a bath, in order to avoid the situation of water intake.
