Abstract

PURPOSE:To obtain two watches having a continuous movement of hands and a step movement of hands respectively via a common part, by selecting a 2-step or 4-step reduction bearing provided to a plate and a back of a watch respectively and then transmitting the rotation of a motor to a second wheel. CONSTITUTION:A 2-step and 4-step reduction bearings are provided to a plate and a back of a watch respectively. In the case of a watch having a step movement of hands, the rotation of a rotor 1 is transmitted to a center wheel 8 via wheels. While in the case of a watch having a continuous movement of hands, the rotation of the rotor 1 is conveyed to the wheel 8 via a 2nd wheel 5, a second wheel 6 and an intermediate wheel 7 respectively.
