This paper describes a new quartz watch driving system we developed. With this system, the second hand of a wrist watch moves smoothly as if it is sweeping. An intermittent movement of the stepping motor is transferred to a smooth sweeping motion due to the spiral spring and the viscous regulator. This system also allows the continued superiority of quartz watches.
