Automatic Mechanical Watch

The oldest is the type of watch, which has a long history. It generally refers to a watch that uses a barrel to store power. The beginning of all power is sent from the clockwork to the second, third, fourth, fifth (escape wheel), clamp and then to the balance wheel, and then the balance wheel reaction force to the horse, so It returns to the position it was in before, so that the whole operation process can be repeated and continue to generate power. Mechanical watches can be divided into two types: hand-winding and self-winding.

Hand-winding watch: By turning the faucet by hand, the winding system is driven to drive the mainspring to be fully wound.

Note: When winding the chain for the first time, first wind it up to the full chain by yourself and see how many laps you have to wind. Later, you can go up to 8 or 9 minutes full in the same way. Do not wind the chain too much to avoid breaking the mainspring.

Automatic winding watch: rely on the swing of the arm to drive the automatic plate to swing back and forth to achieve the effect of automatic winding.

Note: The automatic watch has an unwinding device, so the winding is dissatisfied. When the watch stops, just let the mainspring walk in the last few laps, and the rest depends on the swing of the hand during wearing to achieve the winding effect.

Quartz Quartz Watch

This kind of watch belongs to the second generation. It generally refers to the watch that uses batteries and quartz oscillators to calculate and display time. Its movement is made of quartz. The common ones can be divided into analog quartz watches and digital quartz watches. , The biggest feature is accuracy. Within the normal temperature range, the monthly error is about ±15-20 seconds.

Quartz watches are divided into:

Analog quartz watch: After using battery power to generate frequency from quartz, the IC board is used to divide the frequency and control the coil and magnet to drive the gear train and rotate the hands. The hour and minute hands are basically driven by electricity.

Digital quartz watch: The basic principle is the same as the analog quartz watch, but it does not have a gear train, and directly uses a liquid crystal (LCD) to display the time.

Solar meter

Solar cells are made of silicon wafers with extremely high purity. The silicon wafers have undergone extraordinary treatment to form two extremely thin layers. When sunlight or light shines on the surface of the silicon wafers, light energy can be converted into photocurrent and Light voltage. Electric current flows from the high-voltage solar cell to the low-voltage watch battery to be charged. In order to prevent the voltage flowing into the watch from the solar battery being too high, there are diodes and resistors inside to act as a buffer to protect the watch battery and its life.
