摘要： Disclosed is a timepiece assembly including at least two elements in contact and mobile relative to each other, one of the elements having at least a first contact surface intended to rub against at least a second contact surface of the other element under dry lubrication conditions. At least one of the first and second contact surfaces is covered with a hydrophobic coating having an angle of contact with water greater than 90°, preferably greater than 100° and preferably greater than 110°, and a coefficient of friction lower than 0.15, preferably lower than 0.12 and preferably lower than 0.1, the variation in the coefficient of friction as a function of the relative humidity being lower than 25%, preferably lower than 10% and preferably lower than 5%.

摘要： The display device is arranged in a timepiece which includes a counting wheel and a manual control mechanism which is arranged to permit cyclical starting, stopping and resetting of the counting wheel. The display device includes an indicating member, a unit for moving the indicating member into a first predefined position when the counting wheel is being reset, a unit for moving the indicating member into a second predefined position, different from the first predefined position, when the counting wheel is being started, and a unit for permitting the indicating member to be moved into a reading position following stopping of the counting wheel, the reading position being determined by the position of the counting wheel.

摘要： Disclosed is a timepiece including a case, a movement and a vibration-generating device intended to produce a sound, the latter two accommodated in the case, a device for amplifying the vibrations from the vibration-generating device, and a membrane receiving the amplified vibrations and generating a sound to outside the timepiece. The vibration-amplifying device includes a lever pivotally mounted on a support in a pivoting plane non-parallel to the plane of the membrane and actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever, the lever being integral with the membrane at least translationally in the pivoting plane so a movement of the transmission member, generated by vibration of the transmission member linked to the vibration-generating device and transmitted to the membrane by way of the lever actuated by the transmission member, generates an amplified movement of the membrane for an amplified sound.

摘要： Disclosed is a method of making a timepiece spring from monocrystalline material including the following steps: drawing the spring; identifying one or more zones of weakness of the spring in which or in at least one of which the spring will break in the event of excessive deformation; manufacturing the spring from a wafer of monocrystalline material extending in a determined plane, while orienting the spring in the wafer such that the direction of the macroscopic stresses in the or each zone of weakness when the spring is deformed is substantially parallel to a plane of cleavage of the material intersecting the determined plane. Also disclosed is a timepiece spring obtained by such a method.

摘要： Disclosed is a display mechanism for a timepiece, including a frame, an aperture which is fixed relative to the frame and a first and a second display disc each bearing indications, characterized in that it makes it possible to display the indications of the first and second discs alternately through the aperture. The invention also relates to a timepiece movement including such a mechanism, and to a timepiece such as a wrist watch, a pocket watch, a clock or a miniature clock including such a timepiece movement.
