PURPOSE:To obtain an electronic timepiece which makes a pointer for time display and other members drivable to turn independently while facilitating smaller size and less thickness with simple construction. CONSTITUTION:An analog movement 9 is buried into a housing 5 housed in a case of an electronic timepiece to drive to turn a hour hand and a minute hand at the center thereof and a hole 19 is provided at the peripheral part to house a ring-shaped ultrasonic motor comprising a rotor 14, a stator 15 and a piezoelectric element 16. A calendar plate 18 with a data from '1' to '31' printed thereon is fixed on the rotor 14 and turns by one day in the number of the data printed on the calendar plate 18 once per day in the direction of the arrow A by an ultrasonic driving. A dial plate 6 has a hole for a rotating shaft of the hour hand and the minute hand at the center thereof and a window 20 for a calendar display at the peripheral part to display the data printed on the calendar plate 18. |
