Abstract: A hand for a timepiece including a base is intended to be driven by a drive member of a clock movement to rotate about a first axis of rotation, the base being extended by a first index portion. The latter defines a support for a second index portion intended to be driven in terms of rotation with respect to the support about a second axis of rotation substantially perpendicular to the first axis of rotation by a drive mobile of the clock movement. The hand can be driven conventionally to display the time, in relation to graduations borne by a dial, while rotation of the second index portion allows additional information to be displayed which may be independent of the time. The resulting bulk of this structure is modest and visually de-clutters the display area of the timepiece while allowing several timekeeping complications to be displayed simultaneously.

The intermediate unit also includes at least two contact areas each of which is used for producing a force on the corresponding control element and which are located on both sides of the reception area in the direction of the axis.
