What Is a Video Wrist Watch?

In 1955 Switzerland successfully developed the first hairspring electronic watch. Since then, the watch industry has entered the electronic age, breaking the stable pattern of mechanical watches for about 200 years. The release of timepieces from the purely broken "precision machinery" category has caused rapid and profound changes in the watch industry. In the short period of more than two decades, the left has developed to the fourth generation, and the output has been soaring. Watches with electronic circuits are divided into balance electronic watches, tuning fork watches and quartz watches, depending on the vibration system or oscillator used. Also called electronic watch.

Electronic watch: A watch containing electronic circuits. Depending on the vibration system used or

Electronic watches are watches that use electronic components with microbatteries as energy sources (also using solar energy).

Electronic watches originate from

The electronic watch appeared in the 1950s and it has undergone four generations of evolution.

Mid-to-high-end watches are advised to perform corresponding maintenance every two to three years, replace the water-resistant components, and check the travel time performance and

If water accidentally enters the watch case, a particulate material called silica gel can be placed in a closed container with the watch that has accumulated water. After a few hours, the watch is removed and all the water disappears. This method is simple and economical, without any damage to the accuracy and life of the watch. The silica gel that has been absorbed for many times can be dried at 120 ° C for several hours. The water absorption ability can be regenerated and can be used repeatedly.

If the water is not serious, just watch

Epson and its watch company have developed the world's first

The movement of the "multifunctional electronic watch" is a masterpiece of 1400 watch manufacturing technology and precision craftsmanship. In addition to displaying time, this type of electronic watch has concentrated other functions. As shown

Electronic watches are a new type that only began to appear in the 1950s

Symptom: The display is disordered, the seconds display flickers faintly. Failure reasons: (1) poor contact; (2) integrated circuit failure; (3) the common electrode terminal of the liquid crystal display is broken. Repair method: (1) Pry open the back cover, remove the watch core, loosen the 4 screws on the bottom plate, and remove the bottom plate.You can see that there are two pieces of conductive rubber on the two rows of electrode terminals of the LCD screen. The two rows of electrode terminals have poor contact. You can place a piece of paper of appropriate thickness on the upper and lower sides of the LCD display where it comes in contact with the case, and then install the parts in place, and the display will be normal; (2) Replace the integrated circuit board; (3) Replace the LCD. ^[2]

Avoid getting wet

The tightness of electronic watches is poor. Pay special attention to waterproof and moisture-proof. Because when the electronic watch is wet, it will easily reduce its insulation performance, cause faults such as leakage, short circuit, and even rust inside the watch. ^[3]

Avoid sunburn

The liquid crystal display of an electronic watch can generally be used for about seven years. If the liquid crystal display function is often exposed to sunlight, the aging will be accelerated and the service life will be shortened.

Avoid high temperature

In high temperature environments, the characteristics of integrated circuits inside electronic watches will change, which will directly affect the accuracy of the watch.

Avoid shaking

Because the integrated circuit leads in electronic watches are extremely thin, if they are subjected to strong impact vibration such as dropping, it is easy to damage the internal quartz oscillator or the integrated circuit leads to break, or even change the relative position of each part to stop working. ^[3]

Avoid magnetic fields

Magnetic fields will magnetize the internal parts of electronic watches, so care should be taken to avoid placing electronic watches near magnetic objects such as radios, televisions, or electrical equipment. ^[3]

Avoid X-rays

The radiation effect of X-rays will damage the integrated circuit chip in the watch, or cause the electronic watch to generate interference such as static electricity, affecting its normal function. ^[3]

Avoid using lighting beads frequently

When the electronic watch is running, its working current is 3 ~ 4 microamperes. The silver oxide button battery with a small current discharge is used to press the bright lighting electric beads. The current consumption of the electric current reaches 1.5 mA. Run for hours. ^[3]

Avoid camphor

Camphor causes reactions inside the electronic watch. ^[3]
