The first mechanical clocks were invented in Europe around the start of the 14th century and were the standard timekeeping device until the pendulum clock was invented in 1656. There were many components that came together over time to give us the modern-day timekeeping pieces of today.


A clock is an instrument used to measure, keep, and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year. Devices operating on several physical processes have been used over the millennia.


History of Clocks. When we look across the last 500 years, we can see that development of clocks went through several distinct phases of life. Here you can learn more about them and see how steady rate of technical innovation and fashion swings influenced the modern clock industry.


Water clocks, or clepsydrae, were commonly used in Ancient Greece following their introduction by Plato, who also invented a water-based alarm clock. One account of Plato's alarm clock describes it as depending on the nightly overflow of a vessel containing lead balls, which floated in a columnar vat.


Clocks are devices followed us during the long history of modern human civilization, from the times when sun represented the only way we can reliably track time to the modern day when atom clocks and widespread expansion of digital processing enable us to always be connected with clocks that never show wrong time.


Who Invented the Clock? While devices to measure time have existed for thousands of years, the first mechanical clock was created in 725 by Yi Xing and Liang Lingzan in China. This was the first clock to use an escapement mechanism rather than relying on the flow of water to measure time.


This would be a reliable form of clock if the flow of water could be perfectly controlled. In practice it cannot. The clepsydra has an honourable history from perhaps 1400 BC in Egypt, through Greece and Rome and the Arab civlizations and China, and even up to the 16th century in Europe. But it is more of a toy than a timepiece.


Who invented the clock? Introduction. Many types of clocks are in use today. Each kind has its own inventor and history. But from the beginning, men have used all kinds of objects and materials to be able to keep time. Here are the different types of clocks used and how they were made.


A BRIEF HISTORY OF CLOCKS AND CALENDARS. By Tim Lambert. Early Clocks. Today we take knowing the time and the day of the year for granted but for our ancestors it was far more difficult. Until mechanical clocks were invented in the 13th century there were various ways of telling the time. The earliest method of telling the time of day was the ...


A true free-pendulum principle was introduced by R. J. Rudd around 1898, stimulating the development of several free-pendulum clocks. One of the most famous, the W. H. Shortt clock, was demonstrated in 1921. The Shortt clock almost immediately replaced Riefler's clock as a supreme timekeeper in many observatories.
