Abstract
A method of producing an oscillating weight for an automatic wristwatch. The oscillating weightcomprises a heavy-metal segment and a metallic center portion having a flanged rim. For attaching the center portion to the heavy-metal segment, an arcuate groove is formed in the upper surface of the segment, the flanged rim of the center portion is axially inserted in the groove which is slightly wider than the flanged rim, and at one or more locations a portion of the segment is wedged over the rim or a portion of the rim is wedged in the groove by exerting a localized pressure substantially at right angles to the plane of the center portion.
