The invention concerns an electronic watch including analogue display means formed of at least one hand (10) driven by a stepping motor (12), at least one time base (24, 26) for providing time data (h. m) to means (16) for controlling and driving said stepping motor, a main power source (20), means (22) for detecting a lack of sufficient power from said main power source, non-volatile storage means (32) powered by an additional power source (28), for containing said time data when a lack of sufficient power is detected, and characterized in that said non-volatile storage means are further provided for containing the stepping motor position data (μpas) when said lack of sufficient power is detected.
An electronic watch including analogue display means formed of at least one hand driven by a stepping motor, at least one time base for providing time data to means for controlling and driving said stepping motor, a main power source, means for detecting a lack of sufficient power from said main power source, non-volatile storage means powered by an additional power source, for containing said time data when a lack of sufficient power is detected, wherein said non-volatile storage means are further provided for containing the stepping motor position data when said lack of sufficient power is detected.
