Electronic watch is the internal assembly of electronic components of the table, generally divided into LCD digital and quartz hand type two. Electronic watches can not only display the time, but also display the day and date. With the advancement of time, the latest generation of electronic watch has even appeared heart rate monitoring, step measurement, calling, shooting and other functions, similar to a small cell phone.

The electronic watch is a new type of timepiece that began to appear only in the 1950s. One of the earliest electronic watches was called the “balance-spring electronic watch”, which was born in 1955. This watch is driven by an electromagnetic balance wheel instead of a clockwork, using the balance spring as the oscillator and a micro battery as the energy source to drive the balance wheel through an electronic circuit. Its timekeeping part is exactly the same as that of a mechanical watch, and it is called the first generation of electronic watch.

In 1960, the American Blois Company first started to sell the “tuning fork electronic watch”. This watch uses a metal tuning fork as an oscillator, and the electronic circuit outputs pulse current to make the mechanical tuning fork vibrate. It is called the second generation of electronic watches because it has a simpler structure and more accurate timekeeping than the balance wheel type electronic watches.

In 1969, the world’s first quartz electronic watch was introduced by Seiko-she Japan. The emergence of quartz electronic watches immediately became a mainstream product in the watch industry, with accurate timekeeping and simple structure, easily eliminating the first and second generation electronic watches and even mechanical watches from the market. The quartz watch is also called “crystal vibration electronic watch”, because it uses the “vibration phenomenon” of the crystal piece to time. When a crystal is subjected to an external voltage, it deforms and expands; if it is compressed, it generates electricity at both ends of the crystal. This property is also seen in many crystals and is called the “piezoelectric effect”. Quartz watches use a crystal that “vibrates” periodically and continuously to give us accurate time.

The electronic watch is accurate, does not need to be wound every day, and is cheap, so it is very popular among consumers, but because it is all electronic devices, there are some different requirements when wearing it than the mechanical watch. The electronic watch with liquid crystal display is easy to age under sunlight exposure or long-term high temperature conditions; it is most likely to malfunction when exposed to moisture; the crystal liquid glass and quartz crystal are easily damaged when subjected to violent vibration. When you use the watch for about one year, you should replace the battery with a new one to avoid the battery leakage and damage to the electronic devices, and to save the battery, you should use the lighting and alarm device as little as possible.
