The invention relates to a setting system (1) for a timepiece or piece of jewelry (6). Said system includes: a setting mounting (3);a precious stone (2) mounted in or on the setting mounting (3); anda resilient element (5) attached to the setting mounting (3) so as to flexibly connect the setting mounting (3) to said piece (6). The resilient element (5) has a stiffness between 1.210.sup.5 N/m and 1.4 N/m10.sup.+1, and the combined mass of the setting mounting (3) and the precious stone (2) is between 310.sup.4 g and 410.sup.1 g such that the setting mounting (3) can be oscillated and maintained by movements of the wearer of the piece (6). And when oscillating, the setting mounting (3) oscillates according to an axial and/or radial movement relative to an axis (15) of symmetry at an oscillation frequency between 1 Hz and 30 Hz.

Mechanism (1) for moving an object (11), which is suitable for being integrated into a wearable jewellery or costume jewellery item (3), comprising:a manual drive source (5) which is capable of being driven directly or indirectly by an action of a user and which is arranged to drive a transmission (9) following an action of a user;a support system (13) which carries an object (11) which is intended to be moved in rotation about a first rotation axis (A1) under the effect of the manual drive source (5) by means of the transmission (9), characterised in that the support system (13) comprises a first frame (13b) which is mounted so as to pivot on a frame element about the first rotation axis (A1), and an internal frame (13f) which is mounted so as to pivot in the first frame (13b) about a second pivot axis (A2) which is substantially orthogonal to the first pivot axis (A1); and in that the object (11) is arranged to be driven by an eccentric drive element (15b) which is rigidly joined in rotation with a driving wheel (15) which is arranged to be driven by the transmission (9).

The disclosure provides an example watch. The watch includes (a) a housing having a first face and a second face and a cavity extending therebetween, where the first face includes a first bezel coupled to a first transparent watch crystal, (b) a disc disposed within the cavity between the first face and the second face and coupled to the housing, where the disc comprises a watch face for indicating time, and (c) a case cap removably coupled to the second face of the housing, where the case cap includes a casing having a first side configured to mate with the second face of the housing and a second side configured to be engraved.

A chronometer to monitor the passage of time prior to a projected date of birth of a baby and to recognize and celebrate the birth of the baby. The chronometer includes a generally hollow egg-shaped housing including a bottom, a top, a hinge mechanism, and a latching mechanism. The hinge mechanism rotatably connects the top to the bottom so the top can open and close. The latching mechanism releasably connects the top to the bottom. The chronometer also includes a replica of a young chicken housed in the chronometer, and includes a display to indicate the length of time until the projected birth date of the baby.

A display system is provided, configured to be integrated in an accessory to be worn by a wearer/user as an article of clothing, an item of jewelry, a wristwatch, a pocket watch or any other fashion item. The display system includes: (a) a source of electrical energy, (b) one or more light sources, (e) a source of mechanical information, visual animation or visual presentation, (d) a transformation device for transforming such information or visual animation into a luminous information or visual animation, and (e) a control device adapted to allow the user/wearer to control the activation of the system. In this manner, the system is able to provide a luminous information, visual animation or visual presentation.

A watch glass includes a first glass, second glass and a decorative element, in particular a gemstone. Here, the first glass and the second glass are connected to one another via a connecting intermediate layer. The first glass includes a continuous recess. The decorative element includes a base region, which is arranged settingless in the recess of the first glass and in direct contact with the connecting intermediate layer. Further, a watch can include such a watch glass.
