A combined device applies an axial force to a timepiece component, and simultaneously measures the axial distance between a reference and a surface of the component. The device includes a support carrying a measuring body which includes a measuring unit for carrying out an axial measurement of the position of this surface, and a controller operated by a user or by an automated manipulator, for applying to this surface, a characterised axial force transmitted to the bearing and measuring point by a calibrated axial resilient return device. The device is used by having a stack of flat, specific resilient elements, which are characterised by the combined force characteristic thereof as a function of the applied axial stroke, impart to the controller the rotational or axial stroke which corresponds to the specific axial force to be applied.

A press for driving a crystal or a bezel into a watch case middle, including a support designed to hold the middle in position, and a bracket supporting a tool-holder to which a tool is attached, the tool-holder being movable in translation and cooperating with a handling member so as to slide relative to the bracket along an axis A-A when solicited by the handling member, the support including at least two jaws intended to cooperate with the middle so as to ensure that it is held in position, each jaw being movable in a plane P orthogonal to the axis A-A.

A watch is delimited by a case formed of a back cover and of a middle part. A timepiece movement is disposed in a casing ring housed inside the watch case. The watch also includes a dial disposed on top of the casing ring and held by a fixing ring. The fixing ring has an S-shaped cross-section. An upper branch of the fixing ring is supported on the dial and a lower branch of the fixing ring is supported on the casing ring. The lower branch of the fixing ring is clamped between the middle part and the casing ring, so as to grip the dial between the upper branch of the fixing ring and the casing ring.
