Title: Solid state watch module construction

Abstract: A solid state watch module construction has a ceramic substrate on which an integrated circuit chip is mounted to provide drive signals for causing an electro-optical display means to indicate the time. The ceramic substrate is interposed between a battery supporting frame and a cell supporting frame which positions the electro-optical display means with respect to the substrate. The battery supporting frame holds a battery in place, which is retained by a battery retaining member. A connector member is disposed between the ceramic substrate and the electro-optical display means to provide electrical connection therebetween. A plurality of tubes are used for fixedly connecting the battery supporting frame and the cell supporting frame.
