Abstract

An electronic timepiece with analog display by seconds, minutes, and hours hands driven by a bidirectional stepping motor, in which the seconds hand can be used to display information different from the seconds count, the time displayed by the minutes and hours hands being conserved and the passage from one information mode to the next being made by a rapid bidirectional catching up. The electronic circuit comprises means for comparison (10) comparing the information delivered by counting means (16, 18) synchronous with the seconds hand and the information to be displayed, delivered by selection means (5, 9, 12). The state of the output of the comparison means (10) acts by control means (FF6, 7) on the stepping motor, so that the seconds hand displays the desired information.
