用电子震颤器的石英表

电子表本来都是用石英晶振频率来计时的！！

采用石英运动吗还是？

A quartz clock is a clock that uses an electronic oscillator that is made of a quartz crystal to keep precise time. This crystal oscillator creates a signal with very precise frequency. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds.
