Who invented the clock?

The mechanical clocks in Europe began in14th century, and the earliest mechanical clock in the world was first made in Milan, Italy around 1335. Later, mechanical clocks appeared in tall buildings in London, France, Paris and Nuremberg, Germany. 1396 crown escapement made in France; 1450, European clockmaker Hooke invented the clockwork device; At the end of 15 and the beginning of 16, Italy, France and Germany successively tested egg-shaped watches. 1535, German locksmith Peter Henlan made the world's earliest iron clockwork. 1583, Italian scientist Galileo published the famous theory of pendulum isochronism, and then invented the dynamic pendulum as the regulator of clocks and watches; 1656, the Dutch physicist huygens successfully made the first pendulum clock. The appearance of pendulum clock promoted the development of clock manufacturing. Geneva, France, Germany and London, England are all important producing areas of long-frame pendulum clocks. Prior to this, only the hour hand was installed on the dial of the mechanical clock. Daniel Kyle and others installed a long and short needle in the center of the dial. Short needle, long needle. This device has been used until now. 1644, British scientist robert hooke invented the balance spring of clocks and watches. 1675, the Dutch scientist huygens first replaced the original pendulum with the balance wheel system of the hairspring and made a portable clock. 1756 Switzerland made the first self-winding watch. 1757, Thomas Muji, an Englishman, invented the free-anchor escapement, which marked a major reform in clock technology. 1820, Switzerland developed the first clock that can stop every minute and second at any time. 1842, Adricn Pnilippe made the first watch with a winding handle, which was realized in 1860. The earliest watch in the world was made by Jacques droz and Lester in 1790, but it is not perfect. It was not until 1902 that the first mechanical watch finally came out.
