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.

A dial for a timepiece, preferably a watch, the dial being provided with a relief portion which is made as an assembly of pieces on different levels, juxtaposed on a base, such that the relief portion is formed by the upper surfaces of the pieces. A method for manufacturing the dial with several separate pieces, the upper surfaces of the pieces being subjected to a polishing step and/or possibly an enameling step. The pieces are then cut along a defined contour and then assembled edge-to-edge on a base, so as to create the relief portion.

An anterograde display mechanism including: a first wheel driven by a horological movement; a second wheel coaxial with the first wheel and linked to the first wheel by an elastic organ; a first intermediate wheel driven directly by the first wheel and which directly drives a third wheel bearing a display organ; the third wheel including a smooth angular sector where at least two teeth are truncated; a fourth wheel coaxial and rigidly connected in rotation with the third wheel, the fourth wheel meshing the second wheel via a second intermediate wheel; the anterograde display mechanism being configured so that the rotational speed of the second wheel is less than the rotational speed of the first wheel when the display organ is driven in the angular movements thereof by successive short jumps of an angle (α) between two guide-marks separated by the first angle (α).

A wristwatch (an example of a timepiece) includes a small dial (an example of a dial) and a rotary disk (an example of a rotary member). The small dial includes a sun mark for displaying the state of the sun. The rotary disk covers the small dial and rotates in a 24-hour period. The rotary disk includes the sun state indicator that changes the visibility of the sun mark in accordance with the rotational position of the rotary disk. One of the small dial and the rotary member includes a plurality of numbers (an example of indexes) for indicating time. The other of the small dial and the rotary member includes a time indicator that indicates a number in accordance with the rotational position of the rotary disk. The time indicator and the sun state indicator are disposed relative to each other in a positional relationship such that the visibility of the sun mark by the sun state indicator corresponds to the state of the sun corresponding to the number indicated by the time indicator.

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.

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.

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).

The subject invention is a timekeeping device having a dial with eight evenly spaced hour indicators and one hand rather than two, for indicating both hours and minutes. For optimal accuracy the spaces between the hour marks contain eleven evenly spaced marks that indicate five-minute intervals. At the top of the dial there are three numerals 12, 8, and 4. On the bottom side of the dial are the same three numerals 4, 12, and 8. The numbers are in such order that noon can be placed at the top or bottom and all times will read properly. Additionally, all PM numbers can be increased by 12 to form a 24-hour dial.
