A watch case (6) including a rotating bezel (1), a middle (3) and a connecting spring (2) between the rotating bezel (1) and the middle (3), the connecting spring (2) being accommodated within a first groove (7) formed in an external wall (3a) of the middle (3) and within a second groove (8) formed in an internal wall (1 a) of the rotating bezel (1), the first and second grooves (7,8) being preferably arranged opposite one another. The connecting spring (2) is made of an alloy with memory of shape.

A movement for a timepiece comprises a plate (1) and an annular module (2) circumferentially surrounding the plate (1). The module (2) comprises a mobile ring (2″) mounted so as to be made to rotate about its axis by a rolling means, the mobile ring (2″) carrying a rotary indicator (3). The rotary indicator (3) is an attachment, of which a first part (3A) fixed to a crown (5) arranged on the mobile ring (2″) is flat and parallel to a plane defined by the crown (5) and a second part (3B) is a protruding curved part. The second part (3B), in the shape of a tip, is oriented towards the centre of the crown (5), the crown (5) comprising a housing for receiving one end of the first part (3A) of the rotary indicator (3). The movement further comprises a drive train (4) for driving the mobile ring (2″) in rotation at a speed of rotation imparted by the timepiece movement, such that, when it is driven around the periphery of the plate (1), the rotary indicator (3) displays time information indicating hours, minutes or seconds.

The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.

An annular rotating bezel system intended to be rotatably mounted on a middle part of a watch case inside which is housed a timepiece movement which extends in a plane, including a rotating bezel, an annular holding ring, a toothed ring, and at least one elastic arm of which a free end is elastically and radially meshed with the toothed ring, said toothed ring and said at least one elastic arm being held in an axial direction perpendicular to the plane of the movement in the bezel by the annular holding ring, either the toothed ring or the elastic arm being arranged to be angularly joined to the rotating bezel, and other being arranged to be angularly joined to the case middle; wherein the elastic arm is formed of a flat strip-spring mounted in a cantilever arrangement in the system.

A wearable device is described herein. The wearable device includes a display. The display can be a digital display with analog components. The wearable device also includes an input device. The input device is to control the digital display and the analog components correspond to the digital display. In some cases, the input device is a bezel.

Various example embodiments of the present disclosure provide an electronic device including: a housing including a substantially circular opening and a first surface facing in a first direction; a wearing structure configured to enable the electronic device to be removably worn on a part of a human body and connected to the housing; a display disposed in the opening; an annulus installed on the first surface and configured to be rotatable along a periphery of the opining, the annulus including a second surface facing a second direction opposite the first direction; at least one spacer interposed between a part of the first surface and the second surface of the annulus; and a circuit configured to detect a rotation of the annular member and to change the display at least in part based on the rotation.

An annular rotating bezel system includes a rotating bezel, a toothed ring having a toothing provided with a plurality of teeth regularly distributed over an edge of the toothed ring, and a spring ring which extends in a plane in which it is capable of deforming elastically along a radius. The spring ring cooperates elastically with the toothed ring. The spring ring includes at least two lugs, each lug being configured to be elastically and radially engaged with the toothing of the toothed ring in at least one position of the bezel. At least two lugs are offset from each other by an offset angle, the or each offset angle between two successive lugs having a value different from an integer sub-multiple of 360 degrees, such that, in each position of the bezel, only one lug is elastically and radially engaged with the toothing of the toothed ring.

A decorative item is made of a ceramic material, where ceramic material includes a carbide phase and an oxide phase, the carbide phase being present in a percentage by volume comprised between 50 and 95% and the oxide phase being present in a percentage by volume comprised between 5 and 50%. The decorative item is manufactured by a method of powder metallurgy.

The present invention relates to a display device having a rotatable display unit (12), the display device including: a display main body (10) having the display unit (12) for displaying various items of information; a rotary unit (20) combined with the display main body (10) and having a rotary weight (25) eccentric from the display main body (10); and a rotary base (30) combined with the display main body (10) or the rotary unit (20) to rotate relative to the display main body (10) or the rotary unit (20), in which the rotary unit (20) and the display main body (10) combined with the rotary unit (20) are rotated relative to the rotary base (30) and aligned in a predetermined direction by gravity acting on the rotary weight (25).
