Ultra Fine Enameled Copper Wire For The Watch Coils


When I see a nice quartz watch, I can’t help but want to take it apart and look inside, trying to understand how it works. I am confused by the function of the cylindrical copper coils seen in all movements. I guess it has something to do with taking power from the battery and transferring it to the movement.

Quartz watches work with the power of an electronic oscillator together with a small quartz crystal. Inside the movement is a coil that loops current all throughout the watch. The circuit functions as a carrier of the electrical charge from the parts of the quartz movement.

The watch coil is the entire core part of the watch. Usually the circuit outputs an electric pulse to the coil every second under normal operation. The coil drives a small rotor inside to make the watch move, which plays an essential role in the use of the watch. If the coil is broken, the watch will not move.

Affect the quality of the watch coil, the first thing to bear the brunt is the winding wire.The diameter range of winding wire for watch coils is generally 0.012-0.030mm.

These ultra-fine enameled wires are several times thinner than the hair, If the coil is not controlled properly during the winding process, the wire may be broken. Therefore, the quality requirements for these enameled wire are very high.

Ruiyuan is one of the pioneers in China to produce ultra-fine enameled wire below 0.03mm. Our R&D team has 21 years of market experience, and we have achieved the goal of “zero pinholes after stretching” for ten years. The most important feature of our ultra-fine enamelled wire is strong tension and 0 pinhole. In 2019, the thinnest wire diameter will be 0.011mm, and mass production will be achieved.Welcome everyone to come to consult!
