Abstract

An electrically energized timepiece movement is provided with motion work in the form of a planetary train entirely supported on the frame of a driving motor. Coaxial planet pinions are excentrically located on a minute wheel, one planet pinion engaging a fixed central gear and the other engaging the hour wheel.
