Swatch Group New balance spring made of Nivachron™
Swatch Group presents a new balance spring made of Nivachron™, developed in collaboration with Audemars Piguet.
After silicon, the world’s leading watchmaker is introducing a new balance spring with exceptional paramagnetic characteristics. The new non-magnetic compensating alloy called Nivachron™ was developed with the aim of optimizing the resistance of watch movements to magnetic fields. Magnetic fields, which are pervasive in our environment, severely disrupt mechanical watch movements. They affect a watch’s operation and its performance and can even, in some cases, stop it completely.
The Nivachron™ balance spring offers a number of advantages. It allows a considerable reduction in the influence of the residual effect of a magnetic field on the running of a watch (a reduction by a factor of 10 to 20, depending on the caliber). The Swiss-made balance spring, made of a titanium base, is very effective against temperature variations experienced in wearing conditions. In addition, it offers excellent shock resistance. Ultimately, all of these advantages result in a significant improvement in chronometric performance.
Of all the watch components required to make a timepiece, the balance spring is one of the most critical. Its production requires a high level of know-how and expertise. Swatch Group, in partnership with the Swiss Center for Electronics and Microtechnology (CSEM), has already revolutionized Swiss watchmaking in recent years with its silicon balance springs.
