Abstract: Disclosed is a method for identifying a timepiece including a first component, e.g. the movement, and a second component, e.g. the case. A first zone of the first component of the timepiece is photographed with sufficient enlargement to show therein the tracks and flaws in or on the substrate of the first component in this first zone resulting from the process of manufacturing the timepiece and in particular the tracks or flaws produced when the second component is fitted into the first component. An identification mark (label, chemical or physical modification of the substrate) is applied to a second zone of the second component of the timepiece. These tracks or flaws are converted into a unique code by an appropriate algorithm and this code is associated with at least one item of information contained in the identification mark to form a unique and complete identifier of the item.
Abstract: A shock absorbing coupling device for a timepiece, includes a coupling wheel (2) able to take a coupled position and an uncoupled position, a coupling member (1) bearing the coupling wheel and a coupling cam (6) engaging with the coupling member (1) to define the coupled position and uncoupled position of the coupling wheel (2). The device also includes a locking member (12) rigidly attached to the coupling cam (6) and an intermediate member (9) controlled by the coupling member (1). The intermediate member (9) is intended to engage with the coupling member (1) and the locking member (12) to prevent or limit the movement of the coupling member (1) under the effect of a shock when the coupling wheel (2) is in the coupled position, to thus avoid the coupling wheel (2) leaving the coupled position.
Abstract: Disclosed is a flexible-pivot mechanical component of the type with separate intersecting blades, particularly for timepieces. The mechanical component includes an attachment portion and a movable portion that are connected by first and second resilient blades that intersect in a contactless manner at an intersecting point. The flexible-pivot mechanical component is combined with an adjustment unit making it possible to adjust the position of the intersecting point.
