When the temperature of the electronic watch is between 25 and 28°C, the timing error of one day and night is less than one second. When the temperature is below 0°C or above 50°C, it will slow down by two seconds every day and night. At the same time, when the temperature is as high as 60°C, the LCD panel will turn black, and when the temperature drops below 0°C, the LCD panel will lose its display function. Therefore, in winter, the electronic watch can only be worn on the wrist, and the constant temperature of the human body is used to maintain it. normal timing. In addition, high temperature and low temperature will also cause leakage and corrosion of the movement. The of an electronic watch can generally be used for more than one year, but the lighting consumes a lot of power. The power consumption of turning on for one second is equivalent to more than one hour of timing. The lights will dim when the is nearly depleted, or the digital display will dim or even disappear when turned on. When replacing the battery, if you do not understand the watch repair technology, you should send it to a watch repair shop for installation. Moreover, the specifications are not standardized, and there are many batteries of various brands, which cannot be used arbitrarily.
Attention should be paid to electronic watches: do not press the button too hard to avoid failure; the crystal panel needs to be replaced with a new one after five to seven years; the should be taken out in time when it is out of power to prevent the from corroding the movement. If it is found that the light does not light, the button fails, or the timing suddenly has a large error, it should be repaired in time. It may be that the solder joints of the components are in poor contact or are removed. 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 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. belt
Prevent contact with moisture and moisture to avoid discoloration and deformation of the belt.
Avoid prolonged exposure to sunlight to avoid fading of the belt.
Because the cortex is easy to penetrate, it prevents contact with oily things or cosmetics.
The gold-plated layer on gold-plated watches is mostly 14K gold, which contains a certain amount of silver in addition to 58.5% . After the silver reacts with some volatile industrial gas in the air, a black silver sulfide film will be produced on the surface, so that the gold-plated watch loses its golden luster. Therefore, when wearing a gold-plated watch, avoid contact with chemical substances and exhaust gases, such as gas, liquefied gas and sulfur soap, and always keep the gold-plated watch dry and clean. It is best to wipe with a flannel once a week. In addition, the chloride in the sweat is very corrosive to the gold-plated watch. When the gold-plated watch is stained with sweat, it should be wiped clean in time to prevent the sweat from eroding and causing the watch to lose its luster.
The yellow-plated layer of the yellow-plated watch is a metal film composed of copper, zinc and aluminum alloy. If it is not maintained well, it will easily fade and lose its luster. Before wearing a yellow-plated watch, wipe the case with a clean soft cloth, and evenly apply a layer of colorless , then wear it after drying, and then apply it every 1 to 2 months. After such a treatment, not only the color of the yellow-plated watch can be maintained without being worn, but also its surface brightness can be increased, and at the same time, sweat and moisture can be prevented from invading the watch in hot summer.
