The clock originated in Babylon. Six thousand years ago, the Babylonians made a sundial to judge time by the shadow of the sun. Later, in order to make up for the lack of sundial in dark environment, they designed a dripper to judge the time by the speed of water flow. 1283, the first mechanical clock appeared in England, and the clock tower, clocks and other timing tools were gradually designed.

What is the origin and development of clocks and watches?

1, introduction of origin

In primitive society, people used the color of the sky and the brightness of the sun to judge time. In ancient Egypt, people found that shadows would change with time. In Babylon more than 6000 years ago, a sundial was built with stones, and the sun was used to judge the time, which was also the earliest clock.

2. Development history

The original clock was huge and could not tell the time in the dark, so the copper kettle leaked. Time is judged by the speed of water flow. In 140 BC, the ancient Greeks formed a timer with gears, and in 17 century, pendulums and clockwork gradually appeared, making the time more accurate. 1840, the electric clock appeared, and in the 20th century, the quartz clock era entered.

3, the main classification

Clocks and watches are mainly divided into mechanical power and electric power. Among them, the mechanical clock is a timer that uses the energy released by a heavy hammer or spring as the power to drive the gear to rotate, such as the old desk clock, while the electronic clock represents a timer that uses electric energy as the power, such as an electronic watch.
