It's basically three main materials to create the alarm clock which are plastic, medal and rubber.
Plastic Metal Rubber
The first water clock was used in Egypt in 1500 BC. They found one in the tomb of Amenhotep I.
Radiometric clocks are naturally occurring radioisotopes, such as 14C, with known half-lives, that are used to date organic materials.
The first inventor of the calculating machine was Blaise Pascal.

Plastic Metal Rubber
Well basically there are three main materials needed to make a clock, and they are rubber, medal, and plastic.
A mechanical clock keeps time by counting the oscillations of a pendulum. The potential energy of the pendulum is used to drive a series of gears that helps to keep time.
The mechanical clock was invented by a Benedictine monk or monks, but nobody knows the name of the inventor or inventors. It was invented to help them keep a precise schedule for carrying out religious duties.
People in the beginning used the stars, and the seasons to keep track of time. So there is no one person that discovered time. The first time devices were the sundial, hourglass, and the water clock. In the 1300's is when the first mechanical clock was invented.

The mechanical clock is a medieval invention. The ancient world measured time by sundial and the water clock. Both of these were used by the Babylonians in the second millennium BC and both were improved by the Greeks.
By doing something regularly. Exactly what is done depends on the type of clock. The parts may be mechanical or electronic.
