Electronic watches have a timing error within one second for one day and night when the temperature is 25~28°C. When the temperature goes below 0°C or above 50°C, it will be two seconds slower every day and night. At the same time, when the temperature is up to 60℃, the LCD board will become black, and when the temperature drops below 0℃, the LCD board will lose its display role. So in winter, the electronic watch can only be worn on the wrist, relying on the body’s constant temperature to maintain its normal timing.In addition, high and low temperatures can cause the battery to leak and corrode the movement. The battery of the electronic watch is generally available for more than one year, but the lighting consumes a lot of power, and one second of power consumption is equivalent to more than one hour of timekeeping. When the battery is almost finished, the light will become dim, or the digital display will become dim or even disappear when it is turned on. When replacing the battery, if you do not know how to repair the watch technology, should be sent to a watch repair store installation. And there is no standardization of battery specifications, and there are many different brands of batteries that cannot be used at will.
The electronic watch should not be pressed too hard to avoid malfunction; the LCD board needs to be replaced with a new one after five to seven years of use; the battery should be removed in time to avoid corrosion of the movement by the flowing liquid. The new watch will be repaired in time when the light does not light up, the button does not work, and the timing suddenly has a large error, probably because the component solder joints are not in good contact or are stripped off.
Electronic watches, especially digital electronic watches, are generally less water resistant. Although some of them have “waterproof” printed on the manual or back cover, you should avoid contact with water as much as possible. The structure of an electronic watch is different from that of a mechanical watch, and it is all electronic circuits and electronic components, so if water enters it, it will be “disastrous” and the whole watch will be scrapped. Especially the LCD board and the integrated line are not only afraid of water, but also will malfunction after a long time if they are exposed to moisture. Therefore, it is better to take off the watch when washing face or laundry. When it rains, prevent the rain from splashing on it. If you find that the electronic watch is in the water, or the inner wall of the watch mask gathered moisture, you should immediately send it to the repair store for water removal and moisture treatment.
