Watch provided with a control member

A watch comprising a watch case that comprises:

• a middle,
• a horological movement inside the middle, and
• a control member mounted laterally with respect to the middle;
• the control member being mounted at the outer end of an elongate element that projects out of the middle, said elongate element defining a central axis, the control member being configured to fulfil at least one first function of the watch via a rotation or an axial movement of the elongate element, the watch being provided with at least one additional function that can be managed by an electrical signal;
• wherein the watch comprises:
• at least one strain gauge mounted inside the middle or at least partially in said middle or in an external element fixedly connected to said middle, said strain gauge and the elongate element being arranged so that the elongate element can exert a radial force on said strain gauge when a sufficient actuation force is exerted by a user on the control member in at least one direction substantially perpendicular to said central axis, said strain gauge being arranged so as to produce an electrical signal that is dependent on the radial force and thus on said actuation force, and
• a processor configured to generate a command that manages said additional function on the basis of the electrical signal generated by the strain gauge.
