ABSTRACT:
It comprises a standard electronic movement (13) held in the case (1) by means of an encasing ring (15) made of synthetic material and also containing a large-sized accumulator (30) gripped between two conductive plates (16, 29). The upper plate (16) is covered with an insulating film (18) pierced with a hole (19), through which the blade (14) of the battery receptacle of the movement comes in contact with the plate (16). The other pole of the accumulator is connected to the movement by means of the base (3), the case (1) and the dial (10). The encasing ring (15) carries photovoltaic cells (21) illuminated through indentations (22) of the dial. The timepiece can advantageously be produced in small series, and its power reserve is very high.
