  • Publication number: 20230288877
    Abstract: A device (1) for guiding a rotary shaft (6) of a sprung balance. The device includes at least the rotary shaft and a guide bearing (2) for guiding an end of the rotary shaft of the sprung balance, the guide bearing including at least one blade (3) and a surface (5) for coming into contact with and holding the end of the rotary shaft of the sprung balance. At least one end part of the shaft and at least the blade and the contact surface of the guide bearing are made of a material with a Young's modulus of less than or equal to 100 GPa and to reduce the coefficient of friction of the contacting parts.

The guide bearing includes a blade (3) and a surface (5) for coming into contact with and holding the end of the rotary shaft of the sprung balance. The contacting parts are made of a material with a Young's modulus of less than or equal to 100 GPa and/or to reduce the coefficient of friction of the contacting parts. The device also includes a solid body (15) with a guide opening, such as a hole jewel (15), disposed along the axis of the rotary shaft (6) in a centred position. An end of the shaft passes through the opening without too much angular play caused by the effect of gravity.

  • Patent number: 11662690
    Abstract: A method for manufacturing at least two mechanical parts to be arranged in a timepiece mechanism including magnetised functional areas having antagonistic polarities, the parts being arranged in a timepiece mechanism to cooperate with each other in relative displacement, the method including a step of constructing a blank of each of the two parts including at least one functional area from which the parts are able to cooperate with each other and a step of obtaining each of the parts including a sub-step of transforming said at least one functional area of the blank of each of these parts into a magnetised functional area from which emanates a magnetic field, at least one feature of which is configured so that this magnetic field participates in achieving a separation of the magnetised functional areas of the two parts when they are in a stop position in the mechanism.

  • Publication number: 20220276610
    Abstract: The invention relates to a method for bonding timepiece components, comprising applying an adhesive to a first and/or second timepiece component to be bonded to one another, and depositing an adhesion layer onto at least one of the first and second components to be bonded by spraying a primer composition in a localised joining area followed by the solidification of the primer composition. The adhesion layer is deposited prior to the application of the adhesive if the adhesive is applied to the one or more same components as the adhesion layer.
