Watch provided with a control member

A watch comprising:

• a watch case that includes a middle, a horological movement inside the middle, and a control member mounted laterally relative to the middle, the control member being configured to control at least a primary feature of the watch, the watch being provided with one or more additional features capable of being managed by electric signals;
• a magnetic ball partially incorporated into the control member such that said magnetic ball can pivot about a center thereof in three spatial directions, the center remaining unmoving relative to the control member, and such that the magnetic ball can be accessed by a user of the watch such that the user can manually pivot the magnetic ball;
• a magnetic sensor arranged in a fixed manner relative to the watch case, said magnetic sensor being configured to detect an orientation of a magnetic field generated by the magnetic ball and to provide an electric signal representative of said orientation;
• and
• a processor configured so as to manage said one or more additional features based on of the electric signal generated by the magnetic sensor,
• wherein the control member is capable of being displaced between a first position close to the middle and at least one second position located further away from the middle.
