Abstract

An electronic timepiece with a first and second electric motors for driving time indicating hands with a set of gear wheels, and a microcontroller connected to the motion sensor and controlling each motor. A motion sensor includes a movable element arranged to move freely inside a structure connected to the timepiece movement. As a function of the position and movement of the moving element inside the housing, a first and second electric signals, different from each other, are generated by the motion sensor for the microcontroller in a defined time period to determine whether the timepiece is in use. If only one electric signal is detected by the microcontroller in the defined time period, the timepiece changes into a sleep mode, by stopping at least the first electric motor intended to drive the seconds hand.
