摘要:
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.

Set of luminous display hands for a portable object which houses an electrical energy supply source, the set of luminous display hands including first and second superposed luminous display hands each provided with a hole for the passage of a drive arbour, the drive arbour of the second luminous display hand being arranged concentrically inside the drive arbour of the first hand with insertion of an insulating layer between the two drive arbours, the first and second luminous display hands respectively carrying a first and a second light source, the first pole of the first light source being electrically connected to a first terminal of the power supply source via the drive arbour of the first luminous display hand, the second pole of the first light source being connected to the first pole of the second light source via a contact piece, and the second pole of the second light source being connected to the second terminal of the power supply source via the drive arbour of the second luminous display hand.
摘要:
A method of fabricating a liquid crystal display device including a reflective or transflective 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 beneath the front substrate, parallel to and at a distance from the latter, these two front and rear substrates being joined to each other with a sealing frame which defines a sealed enclosure in which a liquid crystal composition is confined, the front and rear substrates being coated on their opposite faces with electrically conductive transparent electrodes and counter-electrodes, the optical properties of the liquid crystal composition being modified by application of an electric field at the point of intersection between an electrode and a corresponding counter-electrode.
摘要:
An external element made from a first material for a wearable object, the first material being an insulating ceramic, wherein a surface of the external element is at least partially treated to include at least one conversion with an electrical conductivity.
摘要:
A method for assembling a stone on to a mounting includes sinking the stone into an adhesive layer on a substrate and then positioning a setting sheet around the stone above the adhesive layer so as to form a peripheral free space between the setting sheet and the stone, at least at the level of the girdle and of areas of the crown and the pavilion adjacent to the girdle. Then, a metallic layer is deposited in the peripheral free space from the setting sheet, at least at the level of the girdle and of the areas of the crown and the pavilion adjacent to the girdle, such that the metallic layer and the setting sheet form the mounting.

摘要:
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.
摘要:
A display device for displaying the weather on demand. The display device includes a first indicator member mobile and having a representation of the sun. This representation of the sun is totally or partially concealed by a concealing element that is located on a second mobile indicator member when the user requests it and in particular via a control unit.
