What are the product types of quartz watches?
Digital quartz electronic watch
A watch that combines the piezoelectric effect of a quartz crystal and a bipolar liquid crystal display. Its function is completely completed by electronic components.
Analog quartz watch
The energy for the quartz watch comes from a silver oxide button cell. After the silver oxide button cell provides a specific voltage to the integrated circuit. The oscillator circuit and the quartz resonator are used to vibrate the quartz oscillator to form an oscillator circuit source. Form alternating bidirectional pulse signals, thereby driving the stepper motor to rotate intermittently. Further drive the transmission gear train to make the hands accurately display the time.
Automatic quartz watch
It combines the advantages of an automatic mechanical watch and a quartz watch. It does not require a battery, and the wearer can choose to wind it manually or automatically recharge it. Its operating principle is to use the dancing of the arm to drive the pendulum inside the watch to rotate. Generate energy to drive the internal micro-motor into energy. So as to provide sufficient power for the quartz device in the watch. The excess electric energy will be stored by the miniature capacitor for backup.
Eco-Drive Watch
The solar wafer converts light energy into electrical energy. And the electric energy is stored in the rechargeable titanium lithium ion rechargeable battery. Then the electric energy from the battery generates a pulse signal to the coil through the integrated circuit. And generate magnetic force to drive the stepping motor, push the gear to rotate and drive the pointer to indicate the time. After being fully charged, it can run for about 40-180 days in the dark. Accurate travel time, rechargeable battery life up to 10 years.
