    Abstract: An electronic timepiece includes: a bezel having location markers for indicating positions of the world; a second hand moving relative to the bezel; a memory storing time difference information in which each location marker is associated with information relating to a time zone to which a position indicated by each location marker belongs; and a controller performing operation control for moving the second hand relative to the bezel, and the bezel has a set exception indication position representing non-correspondence to any time zone associated with each location marker by being in a predetermined positional relationship with the second hand, and the controller causes the second hand and the exception indication position to be in the predetermined positional relationship when there is no location marker associated with a set time zone, during display relating to the set time zone for a date and time to be displayed.

    Abstract: A driving unit includes a rotor, a plurality of vibratory members, and a driving circuit. The vibratory members each include an action part in contact with the outer periphery of the rotor and a motional part including an expansion-and-contraction driver to expand and contract in response to an applied voltage. The motional part allows the action part to slide along the rotational direction of the rotor. The driving circuit applies voltages to the expansion-and-contraction drivers. The vibratory members are disposed in such a way that the action parts of the vibratory members hold the rotor between the action parts.
