1. An electronic timepiece comprising:
- a first indication member for indicating time;
a driving mechanism for driving the first indication member to indicate the time;
a second indication member for indicating information other than that indicated by the first indicating member; and
a piezoelectric actuator arranged adjacent to the second indication member and having a piezoelectric element for undergoing vibration in response to application of an alternating voltage, the piezoelectric element having one side that is brought into direct contact with the second indication member while undergoing vibration in a given direction to cause the second indication member to undergo movement in the given direction.

Abstract
An electronic watch which can be small-sized even with an additional mechanism such as a calendar mechanism. In the electronic watch, a rectangular piezoelectric oscillator 32 acting as a piezoelectric actuator is forced at its end face to contact with a beam portion 35, which is mounted on a date ring 31 acting as a second indication member, thereby to drive the date ring 31 directly.
