Abstract
Timepiece including indicator members actuated or not actuated by the movement. These indicator members are composed of movable hour marks represented by the faces of the studs (30, 40) mounted on staffs having planet wheels (34) driven by a rack (50). The faces of the studs carry stones of various colors. When the movement operates the rack, it determines the change of the hour marks. When operation by the movement is disengaged, manual control elements allow the hour marks appearing on the dial to be changed.
