Incabloc is a shock protection system used in mechanical watches to prevent damage to the delicate pivots and jewels of the balance wheel.
Incabloc is a Swiss shock protection system that cushions the balance wheel's pivots against impacts. When a watch is dropped or knocked, the lyre-shaped Incabloc spring allows the balance wheel pivot to move slightly, absorbing the shock energy and snapping back to position — preventing the delicate pivot from breaking. Its distinctive lyre spring shape makes it visually recognizable under magnification.
Both Incabloc (Portescap) and KIF (Swiss lever) are shock protection systems using spring-mounted jewel settings, but they differ in spring shape. Incabloc uses a distinctive lyre-shaped spring, while KIF uses a different clip design. Both work on the same principle of allowing the pivot to deflect under shock, but watchmakers and brands often prefer one over the other based on movement caliber specifications.
Yes — Incabloc (and equivalent systems) protect against typical daily shocks including drops from reasonable heights and bumps. All quality watches with shock protection can withstand everyday activity. However, no shock system protects against severe impacts. Activities with extreme vibration or impact (jackhammering, extreme sports) can still damage movements regardless of shock protection.
