A timepiece display mechanism for a watch includes a roller pivoting about a main axis and including flaps, each pivoting about a secondary axis parallel to the main axis and having two faces, a first driver for pivoting the roller about the main axis, and a second driver for pivoting a flap about its secondary axis, in a determined position of this secondary axis relative to the main axis, and which include, at each flap, a drive pinion cooperating with a controller to modify, in sequence or continuously, the position of the successive flaps of the same roller or to modify, on demand, the position of a specific flap.

Disclosed are an inner roller, a time display structure and a timepiece. The inner roller includes a rotating rod and a plurality of rotating wheels, the plurality of rotating wheels are provided on the rotating rod at intervals, each of the rotating wheels is provided with numbers, the numbers on the plurality of rotating wheels are different and there are twelve numbers in total. The described inner roller can be used in cooperation with an outer barrel of a timepiece, so that the number of a certain rotating wheel on the inner roller at a certain time can be displayed by a window, so as to complete the display of time (the time can be hour or minute). The time display structure includes an outer barrel and the described inner roller. The timepiece includes a movement including the described time display structure.
