Huygens contracted the construction of his clock designs to clockmaker Salomon Coster, who actually built the clock.įrom its invention until the 1930s, the pendulum clock was the world’s most precise timekeeper, accounting for its widespread use. The pendulum clock was invented in 1656 by Dutch scientist and inventor Christiaan Huygens, and patented the following year.
A CLOCK PORTABLE
The invention of the mainspring in the early 15th century allowed portable clocks to be built, evolving into the first pocketwatches by the 17th century, but these were not very accurate until the balance spring was added to the balance wheel in the mid 17th century.
The astronomical dial and the mechanical clock was made and installed in 1410. It’s the oldest still working intact example of its kind. Prague astronomical clock mounted on the wall of Old Town City in Prague. An astronomical clock is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the sun, moon, zodiacal constellations, and sometimes major planets. Mechanical clocks became widespread in the 14th century, when they were used in medieval monasteries to keep the regulated schedule of prayers.Īstronomical clocks were start to be made in 14th century.
The first mechanical clocks, employing the verge escapement mechanism with a foliot or balance wheel timekeeper, were invented in Europe at around the start of the 14th century. The earliest known clock with a water-powered escapement mechanism, which transferred rotational energy into intermittent motions, dates back to 3rd century BC in ancient Greece.Ĭhinese engineers later invented clocks incorporating mercury-powered escapement mechanisms in the 10th century, followed by Arabic engineers inventing water clocks driven by gears and weights in the 11th century. The second was defined by the ancient Babylonians to be 1/84,600 of a day.
