Abstract: A method for the fine adjustment of the rate of a mechanical oscillator with an oscillating inertial mass, equipped, in a first step, with an actuator made of material suitable for irreversible local micro-expansion under the action of laser fires, to impart to an inertia-block a radial travel during suitable laser fires on a writing zone of the actuator, in a second step, the initial rate of the oscillator is set and measured, in a third step, the direction and the value of the deviation required to achieve a predetermined rate range, and of the travel to be imparted to inertia-blocks are calculated, in a fourth step, a writing zone is subjected to femtosecond laser fires to create expansion lines by local molecular expansion to radially deform the actuator, in a fifth step the rate is measured and the third step and fourth step are repeated if required.

Abstract: A one-piece mechanical timepiece part formed by a gear for timepiece mechanisms, a wheel for timepiece mechanisms and/or a pinion for timepiece mechanisms, and its related method. The method for manufacturing the one-piece mechanical timepiece part by laser light includes the steps of providing a one-piece material part, oscillating and/or rotating the rotary element and forming the one-piece mechanical timepiece part by power and time modulation of the laser light.

Abstract: A display mechanism of a watch including at least one indicator member and a drive member assembly. The indicator member is mounted to rotate about a first axis of rotation and is configured to indicate a time. The indicator member also has a second axis of rotation extending along the indicator member and a rotary element mounted to rotate about the second axis of rotation. The drive assembly includes a first drive member and a second drive member such that the first drive member drives the rotary element when it is moving about the first axis of rotation.

Abstract: A method for assembling a stone on a setting support, the stone being cut to exhibit a table, a crown, a girdle and a pavilion. A substrate with a recess for the stone, the recess forming, between the substrate and the stone, a peripheral free space in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, the peripheral free space including a bottom having a conductive surface. Electroplating, in the peripheral free space, a metal layer in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, so as to confine the girdle in the metal layer to form, around the girdle, the setting support. The stone and its setting support are released from the substrate.
