Hot Selling OEM Fashion Luminous Silicone Tape Designer Chronograph Wristwatch

Attention should be paid to the electronic watch: press the button not too hard to avoid failure; The LCD panel needs to be renewed after five to seven years of use; The battery should be taken out in time when it has no power to prevent the fluid from corroding the core. If the light is not on, the button is out of order, or there is a sudden large error in timing, it should be repaired in time. It may be due to poor contact or removal of the component solder joint. The waterproof performance of electronic watches, especially digital electronic watches, is generally poor. Although some have the words "waterproof" printed on the manual or back cover, try to avoid contact with water. The structure of electronic watch is different from that of mechanical watch. It is electronic circuit and electronic components. In case of water, it will be "catastrophic" and make the whole watch scrapped. In particular, the LCD panel and the integrated line are not only afraid of water, but also suffer from moisture. They will fail over time. Therefore, it is best to take off your watch when washing your face and clothes. Avoid splashing rain when it rains. If water is found in the electronic watch or moisture is accumulated on the inner wall of the watch cover, immediately send it to the watch repair shop for water removal and moisture removal.

When the temperature of the electronic watch is 25~28 ℃, the timing error of one day and night is within one second. When the temperature is below 0 ℃ or above 50 ℃, it will slow down for two seconds every day and night. At the same time, when the temperature reaches 60 ℃, the LCD panel will turn black. When the temperature drops below 0 ℃, the LCD panel will lose its display function. Therefore, in winter, the electronic watch can only be worn on the wrist, and its normal timing is maintained by the constant temperature of the human body. In addition, high temperature and too low temperature will also cause battery leakage and corrode the movement. The battery of the electronic watch can be used for more than one year, but the power consumption of the lighting lamp is large. The power consumption of turning on for one second is equivalent to more than one hour. When the battery is almost finished, the light will dim, or the digital display will dim or even disappear when it is turned on. When replacing the battery, if you do not understand the meter repair technology, you should send it to the meter repair shop for installation. Moreover, the battery specification is not standardized, and there are many batteries of various brands, which cannot be used at will.
