HOROLOGICAL DISPLAY MECHANISM WITH AN ELASTIC HAND
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.
Electronic timepiece
An electronic timepiece includes: a 6 o'clock information display unit that displays one display mode among a plurality of display modes including a barometric display mode in which a barometric pressure is displayed, using a first display hand; a 10 o'clock information display unit that displays a change in the barometric pressure using a second hand in a case in which the display mode displayed by the 6 o'clock information display unit is the barometric display mode; a 2 o'clock information display unit that displays the barometric pressure using measurement display hands in the case in which the display mode displayed by the 6 o'clock information display unit is the barometric display mode; and a time display unit that displays a time using an hour hand and a minute hand irrespective of the display mode.

HOROLOGICAL MECHANISM FOR ACTUATING A FLEXIBLE HAND
A flexible hand actuation mechanism to which a disk of a horological movement applies a first angular rotation (θ1), the flexible hand including a first cannon and a second cannon connected to a point of the flexible hand via flexible arms, an operating position where the first cannon and the second cannon are coaxial about an exit axis, the first cannon being fitted with a first defined prestress angle, the second cannon being fitted with a second defined prestress angle of opposite direction to that of the first cannon, the actuation mechanism being arranged to actuate the flexible hand such that the latter changes shape and length in the desired manner by varying the angular position of the second cannon with respect to the first cannon by pivoting about the exit axis.
HOROLOGICAL DISPLAY MECHANISM WITH ELASTIC HAND
A horological display mechanism (10) with elastic hand (1), including means for driving barrels (2; 4) coaxial at the ends of a flexible blade (3), including a differential mechanism with an input frame (180) including an input toothing (182), free to rotate and carrying an intermediate wheel (103) and a satellite (101) meshing with each other, this satellite (101) including an eccentric finger (1010) traveling the track (105) of a fixed cam (104), and returned against it by the elasticity of the elastic hand (1), the input frame (180) including a shaft (185) carrying, coaxially, a first cannon-pinion (1020) including the first barrel (2) and a second cannon-pinion (1040) including the second barrel (4), the toothing (1049) of one of which meshes with the toothing (1039) of the intermediate wheel (103), and the toothing (1029) of the other one of which meshes with the toothing (1019) of the satellite (101).
VARIABLE-GEOMETRY TIMEPIECE DISPLAY MECHANISM WITH RESILIENT HAND
A variable timepiece display mechanism includes a resilient hand with a drive pipe integral with a single-piece flexible strip including flexible segments joined at tips, a first segment thereof extends between the first pipe and a first tip. The mechanism also includes a driver for driving the pivoting of the pipe, and a stressor for stressing the first flexible segment in order to vary the position of the first tip relative to the output axis, as a function of the forces applied to the flexible strip. The drier and/or the stressor includes a first shaped gear train and/or a second shaped gear train in order to accelerate, stabilize the speed of, or slow at least the pipe over a part of the angular travel thereof.
Timepiece display mechanism comprising at least one resilient hand
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.

POINTER DISPLAY APPARATUS AND POINTER OPERATION CONTROL METHOD
A pointer display apparatus includes a pointer which operates in an operation range; and at least one processor which controls an operation of the pointer. In a first display mode in which the processor displays display contents with the pointer, the processor sets an evacuation state of the pointer in an evacuation operation in which the pointer is temporarily evacuated from a pointing range to be different from an evacuation state of the pointer in a mode other than the first display mode.
TROCHOIDAL DISPLAY MECHANISM
The invention relates to a mechanism for displaying an information for a timepiece, comprising a mobile (10) intended to be driven in rotation by the movement of the timepiece about a display axis (17), a satellite (20) pivoted on the mobile (10) about a satellite axis (27) parallel to the display axis (17) and remote from a non-zero distance d1 thereof, a display area (80), an indicator (50) secured to the satellite (20) and the position of which relative to the display area (80) provides the information, and a crown (30) centered on the display axis (17) and kinematically connected to the satellite (20). The mechanism is particular in that the indicator (50) is located at a distance d2 from the satellite axis (27), which is greater than or equal to the distance d1.
