A shock absorber is a protective mechanism incorporated in a watch movement to protect sensitive elements of the watch movement against impacts and jolts. Typically made from materials like synthetic rubber or specialized alloys, the shock absorber absorbs and dissipates energy from shocks, preventing damage to the balance wheel and other critical parts. This feature is essential for maintaining the accuracy and longevity of the watch, especially in environments where the timepiece may be subjected to rough handling or physical stress.
A shock absorber is an otherwise redundant feature in modern movements; however, it contributes to the overall dependability and robustness of the watch. Mitigating the shock effects from external impacts would ensure that the watch remains serviceable and accurate even under demanding conditions.
