Quartz clock movement is the most commonly used clock timer in our life, but when it comes to the quartz clock movement wire board on a small silver metal circular thing, many friends do not know what is it, what role it has? Now the small editor tells you, its name and in the quartz clock machine core responsible for what aspect? In the watch industry, it is called quartz crystal vibration (also called quartz crystal). In the quartz clock movement, quartz crystal vibration is responsible for the running frequency, so the quartz clock movement is one of the indispensable electronic components.
At present, quartz clock movement using semiconductor vibration is divided into two classes (one second and 2 seconds), a second level of quartz clock movement poor seconds a day plus or minus one second to contain a second. The national standard is two-second. Some good quartz clock core manufacturers use one-second quartz crystal vibration. For example, the HR1688 standard quartz clock core produced by hengrong clock factory USES one-second quartz crystal vibration, but the price is slightly higher than that of two-second clock. Through this understanding, I believe we all know how to choose the quality of quartz clock core you want.
