Abstract

A timepiece gear member of metal comprising at least one bearing portion (5d, 5e), which is adapted to be supported by a frame, and a pinion portion (5b), is formed by plastic working with the bearing portion(s) and pinion integral with each other. The gear member is formed by die working from strip together with a gear toothed wheel part (5a). The plastic working may be forging or compressing or bending and/or shearing. <IMAGE>
