Solid-state electronic watch assembly

Claim 1

In a solid state electronic watch assembly provided with a watch case having a window at one end thereof; a movement insertable in said case, said movement comprising: A. a module constituted by a dielectric plate on whose obverse face is mounted the electro-optical stations of a time display, each station being formed by a pattern of display elements which are selectively activatable to define different digits, the back face of said plate having integrated-circuit chips mounted thereon to provide the circuits of an electronic timekeeping system which is operable in conjunction with discrete elements and is energized by at least one replaceable power cell, the integrated circuits on the back face being connected by leads passing internally through said plate to said display elements on the obverse face to afford a time display, said back face having a row of module terminals thereon which are connected to said integrated circuits; B. a generally rectangular housing block having wells formed in its forward section to receive said discrete elements and at least one hatch formed in its rear section to receive said cell, said block having a ledge on its forward end on which said module is seatable with its obverse face viewable through said window to expose said time display; C. a rigid printed circuit board overlying the forward section of the block, the discrete elements which are receivable in said wells being supported from the underside of the board, said board having at least one connecting finger extending therefrom which overlies the rear section to engage said cell receivable in said hatch, said discrete elements and said finger being connected by said printed circuit to a corresponding row of board terminals; and D. a flexible connector joining said module to said board and having an array of contacts bridging the module and board terminal rows, the module and the board joined thereto by the connector constituting a unitary sub-assembly which when placed over the housing block with the module seated on the ledge, with the discrete elements received in the wells, and with the finger engaging the cell received in the hatch thereby completes the movement.
