Mechanical watches can be divided into manual mechanical watches and automatic mechanical watches; electronic watches can be divided into digital quartz electronic watches, pointer quartz electronic watches and automatic quartz watches and optical kinetic energy watches.
First, mechanical watch
Mechanical watches can be divided into manual mechanical watches and automatic mechanical watches:
1. Manual mechanical watch: The movement of the hand chain, rotating the crown, the spring inside the movement will release the energy and push the watch to run.
2, automatic mechanical watch: the power of the automatic movement is driven by the weight of the fly in the movement, when the arm of the watch swings will drive the fly to rotate, and at the same time drive the clock in the watch for the watch winding.
Second, the electronic watch
It can be divided into digital quartz electronic watch, pointer type quartz electronic watch and automatic quartz watch and light kinetic energy watch 1. Digital quartz electronic watch: the piezoelectric effect of quartz crystal and the combination of bipolar tube liquid crystal display, its function is completely The electronic components are completed.
2. Analog quartz watch: The energy of the quartz watch comes from the silver oxide button battery. After the silver oxide button battery supplies a specific voltage to the integrated circuit, the quartz oscillator is oscillated by the oscillation circuit and the quartz resonator to form an oscillation circuit source. .
3, automatic quartz watch: the advantages of automatic mechanical watch and quartz watch. It does not require a battery, and the wearer can choose to manually wind up or choose to charge automatically.
4. Photodynamic energy watch: Firstly, the solar energy is converted into electric energy by the solar wafer, and the electric energy is stored in the recyclable titanium lithium ion rechargeable battery, and the electric energy generated by the battery generates a pulse signal to the coil through the integrated circuit to generate a magnetic force. The stepper motor is driven to convert electrical energy into kinetic energy, push the gear to rotate and drive the pointer to indicate time.
