From the mid-19th century, some people put the chronograph on the belt, and started wearing it on the wrist, gradually improving, reducing the body shape, beautifying the style, and developing into a watch.
The world's first watch was made by Patek Philippe in 1868 to the Countess of Koscowicz in Hungary. But this form of timepiece was not popular at the time.
In 1904, the French businessman Louis Vrançois Cartier, who ran jewelry, received a complaint from the pilot friend Alberto Santos Dumont: It is very difficult to take the pocket watch out of the pocket when driving the plane. I hope he can assist. Solve this problem so that you can see the time while you are flying. Therefore, Cartier came up with a method of attaching a pocket watch to his hand with a belt and a buckle to solve the problem of a friend. And this kind of pocket watch tied to the hand is the watch of today.
In 1911, Cartier officially commercialized this form of timepiece and launched the famous Santos watch. Since then, watches have become popular.
After a century of improvement, the Swiss made the quartz clock into a quartz watch for the first time in 1967. The watch was also developed in the form of manual/automatic winding, which was used to display time with quartz, electronics and other powers, and mixed with other simple ones. Functions, such as timing, moon phase, measurement pulse, etc.; modern watch watches add more complex functions, such as: electronic PDA, MP3, mobile phone and other forms. Some watches have also become a kind of jewelry at the same time, the focus is not on the display time, but on its design, brand, material (such as precious metals and diamonds) and other features.
