Following the silicon hairspring, the world’s leading watchmaker Swatch Group has launched a new hairspring with excellent paramagnetic properties. This non-magnetic compensation alloy, called Nivachron ™, was developed to optimize the resistance of watch movements to magnetic fields. The magnetic field is widespread in the social environment, which seriously disrupts the operation of mechanical watch movements. Magnetic fields can affect the operation and performance of a watch, and in some cases can even stop it.
Nivachron ™ hairspring has many advantages, which can significantly reduce the effect of the residual magnetic field effect on the watch operation (depending on the specific movement, it can be reduced by 10 to 20 times). This hairspring is made of a titanium-based Nivachron ™ alloy with a complex composition that is resistant to temperature changes in the wearing environment. In addition, it has excellent impact resistance. Ultimately, all these advantages can significantly improve the watch’s travel time performance.
The balance spring is one of the most critical components when manufacturing watches. The production of balance springs requires a high level of expertise and skill. The Swatch Group, in collaboration with the Swiss Center for Electronics and Microtechnology (CSEM), has revolutionized the Swiss watchmaking industry with silicon hairsprings in recent years.
