Abstract
A time keeping device of an electric timepiece comprising one motor that can rotate in the forward direction and the reverse direction, a branch mechanism, and a plurality of wheel trains that are branched by the branch mechanism, wherein the motor is rotated in the forward direction to drive one wheel train thereby to carry out a mechanical display, and is rotated in the reverse direction to drive the other wheel train thereby to carry out another mechanical display. The time keeping device further comprises a merge mechanism in addition to the branch mechanism, and a plurality of wheel trains that are branched by the branch mechanism and are merged by the merge mechanism. The motor is rotated in the forward direction to drive one wheel train thereby to carry out a mechanical display, and is rotated in the reverse direction to drive the other wheel train thereby to carry out another mechanical display.
