A waterproof smart watch is especially important when you want to swim but are afraid of water getting into your watch. It can not only maintain normal use in the water, but also does not affect your swimming. Why not have the best of both worlds?

Precautions：

• Wearing a waterproof watch when we swim is the best choice.

Swimming with a 100M waterproof watch is safer. Although an ordinary 30M waterproof watch can withstand 3 atmospheres, the premise of detection is laboratory conditions, that is, the temperature is 20-25°, and the water and the watch are still. When swimming, the watch and the water are in relative motion and have a certain impact. The pressure between the water and the watch is usually much greater than 3 atmospheres. Therefore, the watch is prone to water entry.

• Waterproof watches cannot be used in hot baths and saunas.

The temperature in these two cases is too different from the waterproof test temperature. In addition, each part of the watch is different in material, shape and size according to the principle of thermal expansion and contraction. When the temperature changes greatly, the amount of expansion and contraction is different, and it is easy to produce tiny gaps, causing water to enter the watch. Occasionally no water enters, indicating that the watch has good waterproof performance, but in the long run, it will accelerate the aging of the waterproof parts of the watch and affect the normal service life of the watch.

• Detect watches that have entered water.

A watch submerged in water is still waterproof when tested on a waterproof machine. This situation is caused by improper use. The accumulation of cold and heat (such as exposure to the sun or a low-temperature air-conditioned room) instantly deforms the waterproof part of the watch, and water vapor enters. When the environment is normal, the waterproof parts return to normal and still have the waterproof function.
