发明名称 Solid-state electronic watch assembly
摘要 A solid-state electronic timepiece movement receivable within a watch case having an end window therein. The movement includes a plastic block provided at its forward end with a ledge on which is seated a module. Mounted on the obverse face of the module and viewable through the window of the watch case are electro-optical stations of a time display. The operating elements of the stations are connected through the body of the module to integrated circuit chips mounted on the back face of the module. These chips provide the circuits of an electronic timekeeping system operating in conjunction with discrete elements housed in the block and constituted by a quartz-crystal unit, a frequency-adjusting capacitor and a pair of power cells as well as time demand and setting switches. The discrete elements are connected to the system by means of a printed circuit board overlying the forward section of the block and provided with a pair of flexible contact fingers extending over the rear section of the block to engage the poles of the power cells which are accommodated in respective hatches formed in the rear section of the block.
