  • Publication number: 20220137558
    Abstract: A mechanical horological movement (1) including at least one barrel system (2) for driving a set of wheels and power reserve detector. The detector (10) includes a control wheel (3) disposed opposite the cage of the barrel system (2) and is rotated by a complementary wheel (8) at the differential output to determine a power reserve level. An aperture (13) has a first end (21) to define a complete charge of the barrel system and a second end (22) to define a complete discharge. A lever (4) is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element (5) disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.

  • Patent number: 9836024
    Abstract: A timepiece or watch includes at least one resonator, which includes at least one weight that oscillates with respect to a connecting element fixed to a structure of a timepiece movement. The weight is suspended from the connecting element by resilient crossed strips which extend at a distance from each other in two parallel planes. The projections of the strips on one of the parallel planes intersect at a virtual pivot axis of the weight, and define a first angle which is the apex angle opposite which there extends the portion of the connecting element that is located between the attachments of the crossed strips to the connecting element. The first angle is between 68° and 76°.

  • Patent number: 9436162
    Abstract: A method for adjusting an oscillation frequency of a sprung balance assembly, in which a removal or a displacement of material is conducted on a component of this sprung balance assembly under an effect of a pulse of a laser source to conduct a micromachining or microfusion operation on the material of this component to vaporize or displace this material. This pulse is controlled by a controller configured to generate, sequence, interrupt any pulse and to control movements of a beam of this laser source, and the controller is automatically controlled by a measuring or comparing mechanism.
