From the mid-19th century, someone put a chronograph watch on a belt and used it on the wrist. Gradually improve, shrink the figure, beautify the style, and develop into a watch.
The first watch in the world was made by Patek Philippe to the Countess Koscowicz of Hungary in 1868. But this form of timepiece was not popular at the time.
In 1904, Louis François Cartier, a French merchant who traded jewelry, received a complaint from his pilot friend Aberto Santos Dumont. It is very difficult to take the pocket watch out of your pocket when flying an airplane. I hope he can help solve this problem so that you can see the time during the flight. Therefore, Cartier came up with a way to tie the pocket watch to the hand with a belt and buckle. To solve the problems of friends. And this pocket watch strapped to the hand is the watch today.
In 1911, Cartier officially commercialized this form of timepiece. Launched the famous Santos watch. Since then, watches have become popular.
After a century of improvement, the Swiss made a quartz watch for the first time in 1967. The watch is also wound manually/automatically afterwards. Developed to use quartz, electronic and other power to display time. And mixed with other simpler functions. For example, timing, moon phases, pulse measurement, etc. Modern watches have added more complicated functions. Such as: electronic account, MP3, mobile phone and other forms. And some watches have also become a kind of jewelry. The focus is no longer on the display time, but on its design, brand, material and other characteristics.
