In 1873, octagon-model and four-circle-model spring-type pendulum clocks (called bonbon clocks in Japan) were first imported, and later many clock manufacturers sprung up around Japan. On December 3, 1872, the Meiji government abolished the lunar calendar, and then employed the solar calendar and transitioned to the fixed-time method from 1873, which ended the age of traditional Japanese clocks. Hisashige Tanaka, also known as Karakuri Giemon, built a myriad year clock in 1851. In the Edo Period, clock masters made lantern clocks, pillar clocks with hour scales, carriage clocks, and other traditional Japanese clocks. In Japan in 671, Emperor Tenji started measuring time using a water clock and signaling the time by ringing bells and beating drums. in the 19th century made a huge leap of mechanical clocks. The clock industry by handicraft manufacturing grew in Paris and London in the 18th century, and the evolution of rational production system in the U.S.

In 1675, Christiaan Huygens invented a balance-wheel regulator using a spring and produced a portable clock, and then, improvements of escapement and governor advanced, facilitating the development of mechanical clocks. These improved the accuracy of clocks remarkably. The inventions of timepiece technology include the Galileo Galilei’s discovery of the isochronism of pendulums in Italy around 1582 and the Dutch Christiaan Huygens’ invention of a pendulum clock by leveraging the principle around 1656. A mechanical clock driven by a weight was devised around 1300, and it developed to a small clock using a mainspring for power around 1462. In 1090, a water clock tower (the astronomical clock tower) with an escapement was contrived in China. People understood time at night based on the position of stars around 3400 B.C., and then timepieces for measuring time were created using various materials including water, candles, and oil. About 7000 years ago,and around 5000 B.C., sundials were used for time measurement in Egypt. People’s engagement with time is long, and it is considered that time has understood by the position of the sun long time ago.
