The interior of the mechanical clock

In all mechanical watches are distinguished four basic knots - engine, transmission, running gear and regulator having the following main parts:

    spring motor, drum set
    Gear Facility winder, in developing its spring driven sprockets
    anchor wheel associated with second hand items and adjustment
    anchor
    balance

To counter timer in the narrow sense used regulyatorat. Toothed wheels attached to that arrow on the dial, count per unit time. If it is considered that the Earth's rotation axis is uniform, it becomes the scale for comparing intervals. Per unit of time usually taken second or 1/86400 of the day. timer clockregulators have resisted so pipette stretches are equal or of a second, or half, 1/4 or 1/5.

The core of electronic quartz watches were stabilized electric oscillations microcontroller to calculate the time and the derivation of the digital display. Watches that are powered by AC mains, may not have its own generator, and use the variable frequency electrical current. Time display with numbers such as 13:22. Hand-held electronic watches, electronic watches and other. When this timer clock is disconnected from the mains or battery pack, and it starts counting from 12:00, or stay at 12:00 by flashing at regular intervals.

The first hand-held electronic watches have LED display and can show a short time. Then they used the properties of liquid crystals to orient in an external electric field and pass in the direction of light polarization.

Electronic clocks used by the 1960s. Especially for people with impaired hearing, telecommunications companies offer audio, or so-called talking clocks or time communicate a language or produce a beep a number of times corresponding to hours. timer clockradios are called electronic or quartz watches that have the ability to collate their own time on special stations or satellites with GPS.
