A bridge is an essential component in mechanical watches that holds the moving parts of the watch movement in place. Think of it like the supporting beams in a building - it keeps everything stable and properly aligned. Watchmakers need to work with bridges frequently when assembling, repairing, or servicing mechanical watches. The bridge can be made from different materials like brass or steel, and often features decorative finishes. You might also see it referred to as a "movement bridge" or "watch bridge" in job descriptions and resumes.
