• a needle 14 is mounted in such a manner with respect to the dial 7 that the needle 14 can be rotatably rotated about an axis of rotation 18.
• the movement of the needle about the axis of rotation 18 is generally driven by a motor 16.
• the needle 14 comprises a light guide 20 having an input portion 21 and an output portion 22. According to the present invention, it is provided that the input portion 21 and the illumination member 19 are positioned on the axis 18 of rotation, in particular in a manner to facilitate a transfer of light between the illumination member 19 on the one hand, and the input portion 21, on the other hand.
