Electronic watches, especially digital electronic watches, generally have poor water resistance. Although some have the word "waterproof" printed on the manual or the back cover, try to avoid contact with water.
The structure of electronic watches is different from that of mechanical watches. They are all electronic circuits and electronic components. If water enters, it will be "catastrophic" and the entire watch will be scrapped. Especially the liquid crystal panel and the integrated line, not only afraid of water, but also affected by damp, will fail over a long time. Therefore, it is best to take off the watch when washing your face or doing laundry. When it rains, prevent splashing. If you find that the electronic watch has entered the water, or the inner wall of the watch cover has moisture, you should immediately send it to the watch repair shop for water removal and moisture removal.

For medium and high-end watches, it is recommended to perform corresponding maintenance every two to three years, replace waterproof components, check travel performance and movement power consumption, clean the movement, and maintain the appearance, etc. Such maintenance services will effectively prolong the use time of the watch. (1) When wearing a watch, the sweat on the hands is corrosive to the case. The all-steel case is made of nickel-chromium alloy, which has better corrosion resistance. Wipe away sweat often with a soft cloth or put a plastic watch support on it to prevent it from being eroded by sweat.
