Quartz watches can also be called "quartz vibrating electronic watches" because they use the "vibration phenomenon" of quartz wafers. When quartz receives external applied voltage, it will have the property of deformation and expansion. On the contrary, if quartz is compressed, it will generate electricity at both ends of quartz. This property can also be seen in many crystals, called "piezoelectric effect". Quartz watches use periodic and continuous "vibration" crystals to bring us accurate time. Even so, because the quartz crystal used is disturbed by temperature changes, there will be errors, usually 15 seconds per month.

Quartz watches will appear seconds for indefinite calibration now, which is ubiquitous in quartz watches. It is not a quality problem. It is difficult for the stepper motor of the quartz watch to propel the second hand forward steadily at a fixed interval, which will not affect the timing accuracy of the watch. Small gear clearance turns more smoothly. This clearance is necessary. The type of gear determines the clearance size. The clearance of second pin is usually the largest, minute pin is the second and hour pin is the smallest. So many models of second hand and minute hand will shake, which is also the reason. Another case is that the axis of rotation in the middle of the second hand has a certain tilt, which will cause the second hand to deviate from the scale when it moves to some position.
