The invention concerns a timepiece (10) including a display device (26) including a first and second display member (38, 40) displaying first and second pieces of information, the value of the second piece of information being linked to the value of the first piece of information by a reduction ratio, wherein the first (38) and the second (40) display members are rotatably mounted in relation to a plate (42) and are driven by a drive device (44) with planetary gears, characterized in that the second display member (40) pivots on the axis of rotation (A2) of a planet pinion (54). The invention also proposes a timepiece (10) fitted with this display device (26) and a method for manufacturing this display device (26).
A timepiece including a display dial and a display device, which includes a first rotating analogue display member displaying a first piece of information and a second rotating analogue display member displaying a second piece of information, the value of the second piece of information being linked to the value of the first piece of information in a determined reduction ratio, wherein the first and the second display members are rotatably mounted in relation to a plate about the same main axis and are driven in rotation by a drive device with planetary gears carried by the plate, and wherein the drive device includes a motor element provided for driving in rotation a central pinion which is secured in rotation to the first display member, and at least one planet pinion, which meshes with the central pinion and with a crown with an inner toothing, the second display member being driven in rotation about the main axis by the movement of the axis of the planet pinion,
