Advantages and disadvantages of optical power watches

Advantages and disadvantages of optical power watches;

1, the time is right. This is unmatched by other watches. The time base collected by the long-wave time service station is an atomic clock, which is not less than one second for hundreds of thousands of years. The radio clock collects the signals it sends out, and the hands are synchronized with it (standard time).

2. Can check the travel time error semi-automatically. In other words, it has the function of automation. As long as the radio clock can collect the timing signal, it will enter the synchronous state semi-automatically, that is, it can find the time by itself. If the clock is lucky enough to show a slight precision error, it can also correct itself according to the radio signal sent by the time service station. Because of this, it has no "total error" that other clocks have.

It can ensure that all radio clocks are at the same time. Because of this, it can keep pace with the standard time, and there is no difference between all tables, which successfully realizes real-time unification.

Disadvantages: If you use a radio meter, it is best to use it in an open and unobstructed place. This is because the propagation of radio waves will be blocked by terrain and obstacles. This requires us to use it where the signal is good. If the radio clock can't receive the long-wave radio timing signal, it will be used as an ordinary clock, but it can't keep pace with the standard time and correct its error by itself.
