Summary:A stepping motor driven by a time-based electrical driving signal periodically rotates an overhung gear train directly driving the hour and minute hands mounted on a main arbor. The arbor is rotatably mounted in two spaced journals in a single tapered bearing hole in the frame. An intermediate arbor is similarly journaled. The gear train is assembled from only one side of the timepiece. The main arbor, center gear assembly, hands and dial are all added as a subassembly.
