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.

From the middle of19th century, someone tied a belt on the chronograph and put it on the wrist, and gradually improved, reduced and beautified the style, and developed it into a watch.

The world's first watch was made by Patek Philippe in 1868 for the Countess Koskovich of Hungary. But this kind of clock was not popular at that time.

1904, Louis Fran? ois Cartier, a French businessman dealing in jewelry, received a complaint from Alberto Santos Dumont, a friend of the pilot: it was difficult to take the pocket watch out of his pocket when flying a plane. I hope he can help solve this problem and let him see the time during the flight.

So Cartier came up with a way to tie the pocket watch to his hand with a belt and buckle to solve his friend's problem. And this pocket watch tied to your hand is today's watch.
