Plate

A plate is one of the main structural foundations of a watch movement, holding bridges, wheels, jewels, levers, and other components in precise alignment. Plates are essential for the stability and layout of the movement. They may be replaced when damaged by corrosion, impact, stripped screw holes, worn jewel settings, or previous incorrect repair work.
