Automatic Watch Mainspring

The spring of an automatic watch is made of highly elastic alloy steel, which has extremely high fatigue resistance and corrosion resistance. It is tightly curled into a spiral and installed in the barrel, which can be repeatedly contracted and expanded. The selection of high-quality alloys ensures that the efficient energy storage capacity can be maintained during long-term use to avoid metal fatigue. The automatic winding design realizes energy replenishment without manual winding through the rotation of the rotor, which is convenient for users to use in daily life.

The working principle is that the spring is wound up by winding (manually or automatically) to store energy. The automatic watch relies on the wearer's wrist movement to drive the tourbillon to rotate and wind the spring. Then the stored energy is gradually released and transmitted to the escapement through the gear set to drive the operation of the second hand, minute hand and hour hand.

1. No need for frequent manual winding
The spring of an automatic watch is automatically wound through the wearer's daily activities, which increases the convenience of using the watch.

2. Long battery life
High-quality springs can store energy for a long time (generally 36-80 hours), ensuring that the watch runs stably and remains accurate even if it is not worn for a short period of time.

3. Long-lasting and durable
The high-quality spring material ensures that it has the advantages of anti-oxidation, wear resistance and long life, and can maintain excellent performance even after long-term use.

1. Energy storage
The spring is the energy source of a mechanical watch, which is stored through manual winding or the wearer's daily wrist movement. The elastic potential energy generated when the spring is tightly coiled is stored in the spring barrel, which provides power for the watch to operate.

2. Power release
The spring gradually releases its stored energy, converts the potential energy into mechanical energy through the gear train and escapement mechanism, and drives the second hand, minute hand and hour hand of the dial. This energy release needs to be highly stable to ensure the watch's accurate time.

3. Automatic winding
The spring of an automatic mechanical watch cooperates with the rotor to rewind the spring using the movement of the wrist, avoiding manual operation. This function improves the convenience of use and is especially suitable for daily wear.

4. Stable transmission
High-quality springs have uniform output characteristics during energy transmission, avoiding inaccurate timekeeping caused by sudden relaxation of the spring. Ensure that the watch always maintains stable operation.

High-end mechanical watches: Automatic watch springs are the core components of mid-to-high-end mechanical watches, providing brands with accurate timing and stable performance.

Diving watches and sports watches: In sports scenes, the wearer's wrist moves more frequently, and the spring can be wound quickly, suitable for various dynamic environments.

Collection and display: Because of the mechanical beauty of its spring design, it is deeply loved by watch enthusiasts and collectors.

1.How to care for the spring of an automatic watch?
When not worn for a long time, you can use the watch box or manual winding device to wind it. In addition, avoiding excessive vibration and extreme temperatures can also effectively protect the spring and movement.

2. How does the spring of an automatic watch work?
When the spring is wound, it stores elastic potential energy. As the spring gradually relaxes, this energy is transmitted to the escapement through the gears, which drives the watch's hands to move.

3. How long is the life of an automatic watch spring?
Under normal use, it can usually be used for many years, or even more than ten years. The life of the spring depends on the brand, material and maintenance of the watch.

4. What is the material of the spring?
Usually stainless steel or alloy materials are used, which have high elasticity and durability and can withstand frequent retraction and release forces.

5. What should I do if my automatic watch stops?
Automatic watches usually stop running because they have not been worn for a long time or the energy is exhausted. You can resume operation by wearing the watch or winding it manually.
