  • Water clock
    1400 BCE

    Water clock

    Then they used water to predict the time. They waited the water to go out through a small hole.
  • Sun and Moon
    401 BCE

    Sun and Moon

    They used the shadow of the sun to predict the time.
  • Sand clock
    Jan 1, 1337

    Sand clock

    The sand passes through a very tiny hole.
  • Pocket watch
    Jan 1, 1524

    Pocket watch

    It is a watch made to be carried in a pocket.
  • Pendulum clock

    Pendulum clock

    Is a clock that uses a pendulum, a swinging weight, as its timekeeping element.

  • Mechanical clock

    Mechanical clock

    It is an instrument designed to indicate, keep, and coordinate time, through a mechanical system.
  • Quartz clock

    Quartz clock

    Is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time.
  • Digital clock

    Digital clock

    Is a type of clock that displays the time digitally as opposed to an analog clock, where the time is indicated by the positions of rotating hands.
  • Atomic clock

    Atomic clock

    Is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known.
