Watches classification

Mechanical watches

The timing device of the mechanical vibration system, such as the pendulum, balance wheel bell. The working principle is the use of a constant cycle, the continuous vibration of the vibration system; the period of vibration when the vibration is multiplied by the number of vibrations, is equivalent to the time elapsed, time = vibration period x number of vibrations. Generally composed of several parts of the energy, gear train, escapement, vibration systems, pointer institutions and attached institutions. Energy power - spring or weights, mechanical clock, the time on a continuous run for several days the growth rate of the gear train, escapement watches timing frequency in accordance with the "seconds" that people Concept pendulum rudder or wheel controls the speed of the clock, timekeeping (reported engraved) body to tell people: that last sound of a few points.

Electronic watches

The basic parts of electronic components. The working principle of electronic watches and clocks are designed according to the electric magnetism, the magnetic raw power "of the physical phenomena. That convert electrical energy into magnetic energy by the magnetic energy into mechanical energy to drive around the needle operation to achieve timing purposes.

Transistors placed round watch

Dry-cell batteries for energy, using the transistor as a switch, balance spring oscillating system.

Quartz watches

Electronic frequency to control motor operation, driven pointer, to go high precision quartz crystal oscillator. Electronic Quar. That is the electronic movement and quartz movement, a combination of both electronic display to watch there hands walking directions. Movement of such movement, such as the Citizen (Citizen Miyota Co., Ltd.) T250.

Lightwave watches

Light energy wave form through the watch's built-in radio receiver and antenna to receive standard time radio waves issued by the tower, for time and calendar data, and automatically correct the time and date of the watch. Standard time signal is used in the theory of high-precision cesium atomic watches, 100-year error in one second. Citizen of the waves watch all the light energy technology, the use of any visible light as an energy-driven. As long as there is light energy, as long as the received waves will never have the error.
