Solid state watch module construction

A watch module construction comprising:

• a single body of plastic material serving as a substrate and a baseplate, said single plastic body having formed on a first side thereof, a first cavity having a bottom and a second smaller cavity formed in the bottom of said first cavity with a stepped wall formed by said cavities on said first side of said single plastic body;
• a plurality of printed circuit leads directly formed on said stepped wall by a printing technique, and an integrated circuit chip directly mounted in said second cavity on said first side of said single plastic body, said integrated circuit chip having electrical terminals connected to said printed circuit leads and adapted to provide drive signals;
• and
• an electro-optical display means mounted in said first cavity in said first side of said single plastic body and having electrode patterns adapted to provide a display of characters on a viewing surface thereof, said display means having a plurality of electrical terminals connected to said electrode patterns, said electrical terminals of said display means being electrically connected to said printed circuit leads to provide an electrical connection therebetween whereby said display means receives said drive signals from said chip to provide a time indication by means of said electrode patterns;
• said single plastic body having a cutout formed on the opposite second side thereof for receiving a battery, and serving as a back cover of a watch.
