Bridge

A bridge is a structural movement component that holds wheels, pivots, jewels, and other parts in place within a watch movement. Bridges provide stability and precise alignment, allowing the gear train and other mechanisms to function correctly. They may need replacement if screw holes, jewel settings, pivots, or contact surfaces are worn, damaged, or modified.
