    • Disclosed is an analog electronic timepiece having sweep hands. The timepiece is provided with storage means (102) for storing the rotational energy of an actuator (101) intermittently driven by a time-counting circuit (100) and control means (106) for smoothly driving a display device (104) by controlling the rotational energy through first and second link means (103, 105). In one embodiment of the invention, the control means comprises at least a magnet (41), a power generating yoke (42) and a power generating coil (43) and in another embodiment, it comprises additionally a rectifying circuit (108) which supplies an output current to the time-counting circuit through a power source. (109).
      The advantages of the present invention are that due to the provision of the control means including a power generating mechanism, no erroneous indication of the display device due to temperature variations takes place and besides the easiness of adjustment of the load torque, a desired hand-operating mode can be easily selected at choice between stepped and sweep hand modes.
