Quartz clock movement is the most commonly used wall clock timer in our lives, but when it comes to the small silver metal round thing on the wiring board of the quartz clock movement, many friends don know what it is and what it does? Now the editor will tell you, its name and what it is responsible for in the quartz clock movement? In the watch industry, it is called quartz crystal oscillator (also called quartz crystal). In the quartz clock movement, the quartz crystal oscillator is responsible for the travel time frequency, so the quartz clock movement is one of the indispensable electronic components.

Currently, the quartz crystal oscillators used in quartz clock movements are divided into two levels (one-second level and two-second level). The one-second level quartz clock movement has a second difference within plus or minus one second per day. The national standard is two seconds. Some good quartz clock movement manufacturers use one-second quartz crystal oscillators. For example, the HR1688 standard quartz clock movement produced by
