摘要： 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.

摘要： A timepiece display mechanism with a resilient hand including a first and second device for driving, about an output axis, a first and a second pipe mounted at the ends of a flexible strip, and including a display index distant from the pipes, these drive devices being arranged to deform the flexible strip, by varying the angular position of one pipe with respect to the other about the output axis, and to vary the radial position of the display index with respect to this axis, this mechanism includes a first differential on the drive train of the first pipe, one input of which is formed by a first cam, and a second differential on the drive train of the second pipe, one input of which is formed by a second cam.

摘要： A system and method to determine an angular movement of an arbor integral with a crown of a watch, the arbor being rotatable in a longitudinal direction. Included is a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector. Each emitter/detector pair includes a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals and determine a parameter relating to the angular movement of the arbor. The rotating reflector's visible outer surface changes when the reflector rotates on itself in a regular manner, such that the representative electrical signal generated by said detector of the pair has a substantially sinusoidal shape when the reflector rotates on itself in a regular manner in a same direction of rotation.

摘要： The mechanical timepiece movement with power reserve indication includes a barrel system with a winding output connected to a chassis wheel of a differential gear, and with an unwinding output connected to a crown of the differential gear. The differential gear is connected to a power reserve indicator to display the power reserve. The timepiece movement includes at least one locking member disposed on the crown and at least one locking element disposed on the chassis wheel during the rotation of the crown relative to the chassis wheel. The locking member is intended to come into contact with the locking element when the power reserve is at zero, in order to stop the timepiece movement.
