Abstract: A timepiece includes: a movement (10) that has a balance wheel/spring assembly (12) having a system for adjusting the operative length of the spring, which is rotatable; a control member (14) that is accessible, by the user, outside the timepiece; a transmission wheel (22) that is rotatably mounted, on the periphery of the movement (10), onto a frame, the movement (10) being placed inside the transmission wheel, the transmission wheel (22) being kinematically connected or connectable to the control member (14) and moreover being kinematically connected to the adjustment system; and a display part (30) that is kinematically connected to the transmission wheel (22) and drives a display member, intended for displaying the adjustment value that is applied to the operative length of the spring. The display part (30) is formed of movable parts that are mounted onto a first separate module, assembled to the frame.

Abstract: Timepiece with an hour circle formed by a module placed around the movement. The module cover comprises openings at the position of each hour. Inside the module are rockers with decorations in two particular positions. An oscillating mass moves when the inclination of the plane of the timepiece changes and moves the rockers from one position to the other.

Abstract: A timepiece includes: a frame (10) defining a housing designed to accommodate a timepiece movement; and a dial (14) positioned on the frame and defining a plane, the dial including at least one opening (16) whose dimensions are such as to allow at least one index (18) mounted rotationally on the frame to be seen.

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.
