Method for managing the electrical consumption of a watch

A method for managing electrical consumption of a watch, the method comprising:

• determining, by processing circuitry, a need to charge an accumulator of the watch by measuring a charge level of the accumulator;
• and
• calculating an amount to charge the accumulator based on the measured charge level;
• charging said accumulator through guided movement, by a user of the watch, of a control member in kinematic connection to an electrical generator of an electrical energy generation mechanism of the watch, when the need to recharge is determined,
• wherein the control member is a bezel or a crown, arranged on an external portion of the watch and movable by the user relative to a body of the watch, and
• the charging step further comprises, only in response to the processing circuitry determining the need to charge, providing visual guidance via a digital display and/or providing audio guidance to the user indicating to the user a distance of movement and/or a time of movement of the control member relative to the body of the watch that is needed to be performed by the user in order to charge the accumulator the calculated amount.
