Gift Box OEM Fashion Luminous Silicone Tape Designer Chronograph Wristwatch

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.

Timing instruments of mechanical vibration system, such as pendulum clock, pendulum clock, etc. Its working principle is to use a vibration system with constant period and continuous vibration. Multiply the vibration period during vibration by the number of vibration times, which is equal to the elapsed time. Time=the vibration period of the watch × Number of vibrations. It is generally composed of energy, gear train, escapement mechanism, vibration system, pointer mechanism and additional mechanism.
