The main parts of mechanical hours – the engine, the transmission, the motion controller and the dispenser, transmits impulses to the regulator. Over the course of a mechanical clock responds to controller movements. He amerivet certain intervals during the day, for example, a second, half second, quarter second. If this device begins to regulate different meaning, for example, specify a smaller number, then the clock will start to lag.

The accuracy of the clock can be checked using a special device called a thermometer, but this watch will have to open, and therefore it is better to take them in for repair. Note that if the clock is slow, then the main elements of the thermometer too close.

Quartz clock operates with quartz crystals. The main components of such watches is the battery, electronic generator counter divider and a special amplifier, which drives the clock mechanism. Quartz watch can keep up because of the battery. For further reasons to try to change the battery. Keep in mind, quartz watches, lagging one second a day is considered normal rate. Such mechanisms are arranged so that upon detection of faults they just change completely.

Electronic clock consists of a crystal oscillator and counter divider. They are special chips that connect to the generator through the transactions, there is a system for counting the oscillation pulses. Time in an electronic clock is measured by periodic oscillations of the electronic generator. These signals may be repeated after 1 minute, 1 hour etc. if these values change, then the clock will display inaccurate time. The testimony can be corrected by adjusting the stroke.

E-it may lag because of interruptions in the electrical network, from which they feed. More accurate are those hours that are built into various types of equipment. For example, the radio watch can check your progress with the precise time signals from GPS satellites or from a clock radio.
