Abstract: A variable timepiece display mechanism includes a resilient hand with two drive pipes integral with a one-piece flexible strip includes a tip or an index, with a driver for driving the pivoting of the pipe, and a stressor for stressing the strip so as to vary the position of the tip relative to the axis of the pipes, which includes an accelerator or decelerator device arranged such that it accelerates, or stabilizes the speed of, or slows down the first pipe and/or the second pipe over at least part of the angular travel thereof, which includes a device with a first differential gear on the drive gear train of the first pipe and/or a second differential gear on the drive gear train of the second pipe, and at least one cam forming an input of a differential gear.

Abstract: A horological display mechanism with an elastic hand (1) for driving, about a shaft (D), pipes mounted at the ends of a flexible blade (3), arranged to deform the flexible blade (3), including a mechanism acting on the drive train of the first pipe (2) and of the second pipe (4) and which includes two planetary wheels (82; 84) for driving the pipes (2; 4), and an input planet-carrier chassis (180) for driving the hand (1), and rotatable with a regulation cam (801), the track (802) of which includes a rising edge and falling edge. An elastic arm (803) has a distal end which cooperates with the track and a rising edge of which raises the elastic arm (803) away from the axis of the cam to consume torque, and a falling edge which makes the elastic arm move back towards the axis to restore torque to the system.

Abstract: A timepiece resilient hand with drive pipes at the ends thereof, including a display index which is at a variable distance from the pipes, and including flexible segments between each pipe and the index each with a web having a substantially constant section, at least one flexible segment thereof includes discontinuous elements projecting from the web thereof in a plane perpendicular to the axis of the pipes and defining, along this web, an alternation of sections, the stiffnesses thereof per unit of length are different from one another, and/or at least one web includes a succession of areas of opposite concavities, projecting on a plane perpendicular to the axis of the pipes.

Abstract: In a timepiece movement, more particularly a quartz wrist watch movement, having a low-torque stepping motor, there is provided a differential mechanism which drives the hands and makes it possible to move the hour-hand alone in jumps. A cannon-pinion having a toothing acts as a sun gear. A planet gear is mounted on an hour-wheel which acts as a planet carrier. A ring gear takes the form of an annulus having internal teeth which is normally stationary but is controlled by a stem and can be rotated by jumps to cause the planet gear to roll along the cannon-pinion toothing, thus causing the planet carrier and consequently the hour hand to jump.

Abstract: A rotary transmission between a "minute" display mechanism and an "hour" display mechanism is disclosed for use in a digital clock of leaf type. The transmission is disposed between a first bobbin supporting minute's display members and a second bobbin supporting "hour's" display members. The first bobbin carries a planetary gear, which meshes with a ring gear as well as a driven gear formed on the second bobbin. The ring gear has a number of teeth which is different from the number of teeth on the driven gear.
