What was the first clock?
The world's first mechanical clocks are thought to have been tower clocks built in the region spanning northern Italy to southern Germany from around 1270 to 1300 during the renaissance period. These clocks did not yet have dials or hands, but told the time by striking bells.
What are the modern clock called?
Answer: Currently, atomic clocks are the most accurate clocks in existence. They are considerably more accurate than quartz clocks as they can be accurate to within a few seconds over trillions of years.
What do clocks indicate?
Clocks can indicate the hour with Roman numerals or Hindu–Arabic numerals, or with non-numeric indicator marks. The two numbering systems have also been used in combination, with the prior indicating the hour and the latter the minute. Longcase clocks (grandfather clocks) typically use Roman numerals for the hours.
Where did the clock come from?
15th-century rotating dial clock face, St. Mary's Church, Gdańsk, Poland. The word clock derives from the medieval Latin word for "bell"; clogga, and has cognates in many European languages.

How Do Grandfather Clocks Work?
The movements lie at the heart of each pendulum clock. The hour/minute hand’s striking, chiming, and subsequent timekeeping are all dictated by the pendulum’s movement. The weights and hanging pendulum are essential components of every mechanical clock’s mechanism.
Parts of Grandfather Clock
Each movement of a pendulum clock is due to the four fundamental internal elements that make it work. The escapement, gears, setting mechanism, and weight are all elements of the internal parts. Some external parts have been discussed below.
Origin of Grandfather Clocks
The sundial was man’s earliest timekeeping instrument. It was a device that measured the movement of a huge object’s shadow to calculate equal fractions of the day.
How to Take Care of a Grand Father Clock
Examine to see if your grandfather’s clock is balanced and steady. Ensure that the clock’s hands are neither contacting one other nor the dial of the clock. As the pendulum swings, ensure it doesn’t scratch or hit anything. Lastly, double-check that the suspension spring is not damaged and the pendulum is properly hanging.

The word clock derives from the medieval Latin word for 'bell'—clocca—and has cognates in many European languages. Clocks spread to England from the Low Countries, so the English word came from the Middle Low German and Middle Dutch Klocke. The word derives from the Middle English clokke, Old North French cloque, or Middle Dutch clocke, all of which mean 'bell', and stem from an Old Irish root.
History of time-measuring devices
The apparent position of the Sun in the sky moves over the course of each day, reflecting the rotation of the Earth. Shadows cast by stationary objects move correspondingly, so their positions can be used to indicate the time of day. A sundial shows the time by displaying the position of a shadow on a (usually) flat surface, which has markings that correspond to the hours. Sundials can be hor…
Operation
The invention of the mechanical clock in the 13th century initiated a change in timekeeping methods from continuous processes, such as the motion of the gnomon's shadow on a sundial or the flow of liquid in a water clock, to periodic oscillatory processes, such as the swing of a pendulum or the vibration of a quartz crystal, which had the potential for more accuracy. All modern clocks u…
