Abstract

A watch movement frame comprising a plate having openings therein, a bridge, and at least one spacer member mounted edgewise between the bridge and the plate. The bridge includes separate centering structure and securing structure and the edge portion of the spacer member in contact with the bridge includes corresponding separate centering structure and securing structure. The centering structure of the bridge and of the edge portion cooperate to position the bridge relative to the plate regardless of the inclination of the spacer member and the securing structure of the bridge and of the edge portion cooperate to secure the bridge to the spacer member.
