The bridge is in timepiece a part forming part of the blank , counteracting one or more axes of the mechanism of movement to the plate .
A mechanical watch generally comprises a barrel bridge which holds the driving member, a gear train bridge and a bridge holding the exhaust wheel . They are sometimes assembled in one piece. The bridge that holds the pendulum is called the cock.
The bridges are likely to be decorated by anglage, engravings or coasts of Geneva. In the case of a skeleton watch , they are hollowed out in order to give more transparency to the movement.
