Swatch Group, in collaboration with Audemars Piguet, has developed a new non-magnetic compensating alloy called Nivachron.
The alloy was developed with the aim of optimizing the resistance of watch movements to magnetic fields.
The Nivachron balance spring reduces in the influence of the residual effect of a magnetic field on the running of a watch.
The Swiss-made balance spring, made of a titanium base, is also very effective against temperature variations experienced in wearing conditions.
Magnetic fields affect a watch’s operation and can even, in some cases, stop the watch completely.
Of all the watch components required to make a timepiece, the balance spring is one of the most critical.
