PI-1325 - Schwartz ABSTRACT OF THE DISCLOSURE Analog timepiece movement adapted for a large diameter, thin energy cell, the movement comprising a molded frame of insulating material having a top central wall, and having depending peripheral side wall portions. A flat bridge of insulating material divides the movement into an inner cavity. A stepping motor and gear train are disposed in the inner cavity and a quartz crystal is disposed outside of the cavity. One of the wheel assemblies is of non-magnetic material and extends through a hole in by the stepping motor stator. The peripheral wall portions and the bridge together define a circular envelope in the outer cavity adapted to locate and contain said energy cell. The movement is substantially elliptical in shape, the ellipse having a minor axis slightly greater than that of the energy cell, and the quartz crystal is disposed on one end of the elliptical frame alongside the energy cell.
