Abstract: Timepiece display mobile component (1) comprising at least one resilient strip (4) returned to a display axis (DA), to cooperate in a friction drive with an arbor (2) of a drive mobile component (3) of a movement (100) or a mechanism, about the axis (DA), this mobile component (1) includes a flange (5) comprising, facing each resilient strip (4), an aperture (6) for the insertion and guidance of a manual or robotic tool to allow the tool to move the resilient strip (4) away from its rest position, and to insert the mobile component (1) on an arbor (2) when the resilient strip (4) is sufficiently far away to allow this mobile component to pass, and to ensure a constant friction value of all the resilient strips (4) on the arbor (2) when they are in frictional cooperation with the arbor (2) and when the tool is no longer in contact with the resilient strips (4).
