The invention relates to a display device for a timepiece enabling an easy reading of two pieces of information displayed by two different display members. The device (1) includes a first rotary display member (2) for displaying a first piece of information using its position relative to a first reference, and at least a second rotary display member (4) for displaying a second piece of information using its position relative to a second reference, said first display member (2) interacting with first rotation-driving means (13) and said second display member (4) interacting with second rotation-driving means (15, 16), wherein said first (13) and second (15, 16) rotation-driving means of the first (2) and second (4) display members are arranged so that the second reference moves synchronously with the first display member (2). The second rotation-driving means of the second display members includes a linking wheel (15) connected with the second display member (4) and mounted so as to be capable of rotation coaxially to the second reference, and a differential gear (16) kinematically connected by a first input to the first rotation-driving means (13) of the first display member (2), by a second input to the mechanism in charge of the second piece of information, and by an output to said linking wheel (15).
