Timepiece display mechanism

A timepiece display mechanism, comprising:

• a display comprising a shaft, and
• at least one of a plate and a bridge carrying at least one guide device for carrying and guiding said shaft, said at least one guide device comprising a housing arranged for passage of the shaft of the display or arranged to carry the display, and comprising at least one guide bearing for guiding said shaft around an axis,
• wherein said at least one guide bearing is a platform with parallel faces, and includes, on a first side of said axis, a support surface comprising a V-shape or a pad and arranged to center the axis of said shaft on a bisector plane of said support surface which is symmetrical with respect to said bisector plane which passes through said axis, and on a second side of said axis, opposite said first side, a holding element disposed substantially diametrically opposite said support surface,
• wherein said holding element contacts said shaft so as to exert on said shaft a resultant elastic return force directed towards said axis, and to prevent a radial exit, out of said at least one guide bearing, of the shaft inserted axially in a direction of said axis in said at least one guide bearing, and
• wherein at least one said guide bearing is removable and comprises at least one outer surface which is a peripheral surface arranged to cooperate in a complementary manner with a chamber or a bore comprised in at least one of said plate and said bridge, at least in a plane perpendicular to said axis.
