Mechanical watches can usually be divided into the following two types: manual winding watches and automatic winding watches. The power sources of these two types of machines are driven by clockwork in the movement, which drives the gear and then pushes the pointer, but the power sources are different.

Development course:

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. 19 1 1 year, Cartier officially commercialized this form of watch and launched the famous Santos watch. Since then, watches have become popular.

After a century of improvement, 1967, the Swiss made a quartz clock into a quartz watch for the first time. After that, the watch was changed from manual/automatic winding to displaying time with the power of timing and electronics, and other simple functions were mixed together, such as timing, moon phase and pulse measurement. Modern watches have added more complicated functions, such as electronic pocket account, MP3, mobile phone, etc.

At the same time, some watches have become a kind of jewelry, and the focus is no longer on showing the time, but on its design, brand, material (such as precious metals and diamonds) and other characteristics.
