The mechanism that releases a mechanical watch’s gear train in controlled steps and delivers energy to the balance.
The escapement connects a mechanical watch’s gear train to its regulating organ, the balance and balance spring. It repeatedly stops and releases the train while passing energy to the balance to sustain its oscillation. This controlled release allows the stored energy to drive timekeeping rather than letting the wheels run freely. The Swiss lever is one form of escapement. The distinction between distribution and regulation matters when diagnosing a movement: the escapement supplies impulses, while the balance and spring establish the rhythm. Problems in the escapement can nevertheless affect the regularity of that rhythm.

The escapement is core knowledge for a watchmaker, so a vacancy may not name it. In service work, it is often where a fault in timekeeping is traced, and an advisor may refer to it when explaining a mechanical movement. Search local jobs for “watchmaker”.
