Abstract
Abstract A molded printed circuit board mounted in the case of an electronic timepiece has on its back side an oscillating circuit including a quartz crystal element and a condenser, an integrated time keeping circuit and a compartment for a battery. On the front side of the molded printed circuit board there are a plurality of terminal electrodes connected to outputs of the time keeping circuit. Display means mounted in the front of said case overlies the front side of the molded printed circuit board and is connected thereto by a rubber disc connector having conductive portions for electrically connecting input electrodes of the display means with corresponding terminal electrodes on the front side of the molded printed circuit board.
