All modern clocks require four basic components. First, it requires a source of power, either mechanically or electronically. Second, it needs a sort of time base that will give the clock rhythm. Third, it requires a sort of gear system that will allow it different components of time (seconds, minutes, hours). Finally, a clock needs a way to actually display the time.
Revolutionized by the Dutch astronomer Christiaan Huygens in 1656, pendulum clocks were the first clock designed that maintained its accuracy. Several noticeable parts of the pendulum clock are the face of the clock, with its hour and minute hand, one or more weights, and the pendulum itself. Pendulums swing once per second in wall clocks, but it might swing up to twice per second in small cuckoo clocks, and in large grandfather clocks, the pendulum swings once every two seconds. The number of swings in the pendulum clock correlates with the lengths. The weight of the pendulum basically acts as an energy storage device, using potential energy as the weight swings back and forth while run

The quartz crystal is much better for timing than the tuning fork, and quartz crystals had been around for many years in abundance. Only quartz crystals have already been used for many years to give an accurate frequency for all radio transmitters, radio receivers and computers. Quartz is unaffected by most substances and remains crystalline at extremely high temperature. The best shapes are a straight bar or a disk. A bar has the advantage of keeping the same frequency provided the ratio of length to width remains the same. A quartz bar can be tiny and oscillate at a relatively low frequency and is usually chosen for watches not only for size. Modern quartz watches now use a low-frequency bar or tuning-fork-shaped crystal. The electronics of the watch first amplifies noise at the crystal frequency. This builds or regenerates into oscillation, and it starts the crystal ringing. The oscillations are then converted to pulses suitable for the digital circuits. These divide the crystal's frequency down and then translate it into the proper format for the di
