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.
