Knowledge: the error of the watch

The time errors of the watch include the static (not worn) errors and the motion (worn) errors. Static error is the current error of the watch's core, which is related to the quality of the core itself. The dynamic error is related to the wearer's activity, and the dynamic error of the watch is different due to different personal activities.
 
Why is quartz watch more accurate than mechanical watch?
 
This is because the quartz watch is a high-frequency quartz oscillator with 32768Hz, and the normal mechanical watch is a fast frequency of 3Hz, which is 10,000 times the difference. The higher the frequency of the oscillator, the more stable the oscillation, the stronger the anti-interference ability, the more accurate the time of walking, so quartz watches are far more accurate than mechanical ones.
 
In addition, mechanical watches are subject to the effects of gravity on the horizontal and vertical positions due to their own structure. The clockwork is from the top to the relaxed, the moment imbalance, also affects the walk; Therefore, the accuracy of the mechanical watch is difficult to compare with the quartz watch.
