New innovation in resistance to magnetic fields
After silicon, Swatch Group is proud to introduce a new balance spring – a key component in mechanical movements – with exceptional paramagnetic characteristics. Swatch Group, in collaboration with Audemars Piguet, has developed a new non-magnetic compensating alloy called Nivachron™ for this revolutionary balance spring. With its complex composition, the alloy was developed with the aim of optimizing the resistance of watch movements to magnetic fields. 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.
