Since its origins, Incabloc® has been inseparable from Swiss watchmaking, and the majority of the mechanical watches made in Switzerland today use this system to protect their balance-staff pivots from shocks. Developed in the 1930s, the Incabloc® shock absorber relies on a tiny, specially shaped spring calculated for a range of mechanical
functions. The ingenious design of the lyre-spring® ( lyre ) combined with the double cone of the recentering system react instantly to shocks of varying intensity from any direction. The device thus confers unprecedented resistance to the regulating organ of mechanical watches. Incabloc® was adopted by watchmakers the moment it came on the market. The brand, with its lyre-spring® symbol soon became a world reference. The Zutter family’s acquisition of the product from Portescap in 1988 ensures that production remains in its hometown of La Chaux-de-Fonds. The Incabloc SA company took its name from the invention.
