HOW TO CHOOSE A WATCH

In contrast to when the first type, the energy supply mechanism in this case is normal or solar battery. Quartz watch oscillating system mechanism - the pendulum replaces the quartz crystal. Electronic generator based on a quartz crystal provides stable pulses to stepper motor that drives the wheel mechanism watch or canvas strap watch.

That, in turn, moves the hand on the dial. Quartz, unlike mechanical, can have not only mark the arrow, but a digital display. Since the oscillator frequency does not change, quartz watches in cheap watch case are very accurate, it compares favorably with those of mechanical watches. The error of the accuracy of most ranges from 20 to -20 quartz seconds per month. Plant these watches do not need, and can be used from time to time, without worrying that will arise.

But unfortunately, there is nothing eternal and quartz crystal with time begins to "age" which leads peak hours. Although the theory of durability of the quartz watch should not yield to, mechanical precise statistics on the duration of his work still suggests mechanical watches record length of service.

Electronic clock called quartz watch with a digital display. These electrical pulses are converted into signals that are displayed as time shift in seconds and minutes dial. Chance and a hybrid option, when combined with a digital display is used to display the time using the arrows. If the electronic clock in a hurry, or behind, you can correct the testimony, setting new, but the oscillator will remain the same, only in some models of reading amendment involves a change in the oscillation frequency.

All quartz watches are much less whimsical to weather conditions, do not require the plant and are more accurate than mechanical. The watchcase
