    Abstract: A method for manufacturing a reflective or transflective liquid crystal display device including a liquid crystal cell whose liquid crystal molecules are aligned in a planar or vertical manner, this liquid crystal cell being formed of a transparent front substrate located on the side of an observer, and a rear substrate, also transparent, which extends under the front substrate, parallel to and at a distance from the latter, these two front and rear substrates being joined together with a sealing frame which delimits a sealed enclosure in which a liquid crystal composition is confined, the front and rear substrates being coated on the opposite faces thereof with electrically conductive transparent electrodes and counter-electrodes, the optical properties of the liquid crystal composition being changed by applying an electric field at the crossing point between an electrode and a corresponding counter-electrode.

    Abstract: A display device for a timepiece representing the lunar libration phenomenon thanks to at least one Moon disk, to at least one aperture and to at least one drive organ. The at least one Moon disk includes a set of Moon phase representations including at least three Moon phases with a first surface, a second surface and/or a delimitation configured to delimit this first surface and this second surface. The at least one aperture being configured to reveal this set of Moon phase representations and this at least one drive organ is configured to move this at least one Moon disk so as to represent the lunar libration phenomenon.

    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.
