A watch refers to a tool worn on your wrist to time/display time. In English, watch comes from the word wacche in the middle ages. Watches are usually made of leather, rubber, nylon cloth, stainless steel and other materials, and the "meter" showing time is tied on the wrist.
The manufacture and production of watches are based on a simple and witty invention, that is, "clockwork". It can tighten and store energy, and it can slowly release energy to push the running device and hands in the watch to display time. This spring device in the watch is called the mainspring. Watch structure A watch consists of a meter head and a strap (clasp). Among them, the parts of the rice head include: movement, case, bottom cover, mirror, characters (often called dial), hands, handles (also called push) and order (required by some tables).
The working principle of watches, watches are precision instruments used to display time. The principle of this instrument is to use a vibration system with constant period and continuous vibration as the standard. If we know the time (vibration period) required for a vibration system to complete a complete watch vibration and calculate the vibration times, then the time after so many vibrations is equal to the vibration period multiplied by the vibration times.
For most people, watches are only used to tell time, while quartz watches are not only extremely accurate, but also stable in quality and reasonable in price. No wonder quartz watches are widely praised and become the only choice for most people to buy watches. Many people don't even know that watches are divided into quartz watches and mechanical watches! Moreover, mechanical watches need regular maintenance and have strict technical requirements, unlike quartz watches, which are almost stereotyped replacement parts.
