Nivashock is an anti-shock device that was developed by Neuchâtel based Nivarox-FAR around 2003-2004. It was first introduced in the Breguet automatic caliber 777Q at Baselworld 2006. Nivarox-FAR and Breguet are both owned by the SWATCH Group conglomerate and since then, Nivashock is found in other SWATCH brands such as Omega, Rado, Longines, etc.
As with other shock absorbers, it is a spring-loaded mounting system for the jewel bearings that support the balance wheel. Anti-shock devices help protect the balance wheel’s pivots from damage in the event of dropping the watch or hitting it against something hard.
