or SHOCK-RESISTANT Watches provided with shock-absorber systems (e.g. Incabloc) help prevent damage from shocks to the balance pivots. Thanks to a retaining spring system, it assures an elastic play of both jewels, thus absorbing the movements of the balance-staff pivots when the watch receives strong shocks. The return to the previous position is due to the return effect of the spring. If such a system is lacking, the shock forces exert an impact on the balance-staff pivots, often causing bending or even breakage.

Shockproof is a 1949 movie starring Cornel Wilde and Patricia Knight.

Refers to a device's ability to withstand blows or jarring. This feature is especially important with rifle scopes, which are often jerked during recoil.
