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).

A timepiece includes a representation of a non-rectilinear object, the representation particularly including a movable element kinematically connected to a drive mechanism. The representation also includes at least one second movable element, the drive mechanism being arranged such that the movable elements each move, simultaneously and in synchronization, between a first and a second end position, and vice versa, the movable elements forming the representation at a first size and at a second size greater than the first, respectively, when the movable elements are in the first and second end positions thereof.

A decorative article has a substrate of which at least part of the surface is configured with Ti or stainless steel; and a coating made of primarily TiC and disposed on the substrate. The coating has at least a first region, and a second region disposed closer to the substrate than the first region. The elastic modulus of the second region is greater than the elastic modulus of the first region.

A musical timepiece includes a gong fastened to a structure or a resonator of a watch case, the resonator rigidly assembled to the structure around a chamber, by lugs allowing vibration of the resonator within a determined frequency range, the chamber enclosing a sealing element forming with the lugs the only mechanical connection between the structure and the resonator. The structure or the resonator includes a groove receiving a gasket in contact with the structure and the resonator The structure structure or the resonator or the sealing element includes a rigid protruding relief portion compressing a gasket in its groove, with a hardness less than 20 Shore A, for minimum damping of the vibration of the resonator.

A wristwatch includes a main unit, a first design belt detachably attached to the main unit, an identifier that identifies the first design belt, a display device that displays the display content, a memory that stores the display content displayed on the display device, and a display control unit that displays the display content corresponding to the first design belt identified by the identifier on the display device.

The method makes it possible to produce a decorated component for a timepiece or piece of jewellery. This component provided with the decoration may be, for example, a watch hand. To produce said component, a base substrate is used and a micromachining operation is performed on or in the base substrate to obtain an upper part of the component, which is provided with the decoration. The decoration is produced through the thickness of the upper part and in a programmed pattern. Thereafter, the upper part is placed on a luminescent or colored substance to obtain the component.

In a crown for a timepiece including a crown body having a recess formed therein and a decorative jewel fixed into the recess, a bonding agent is disposed between the inner side surface of the recess and the decorative jewel, and the depth dimension of the inner side surface is at least 0.5 mm.

An adjustable timer teaches time in a simple manner to those having difficulty understanding the concept of time. The timer displays remaining and elapsed time. The timer may be set to rotate a shaft at different speeds. A colored disk is attached to the shaft. Boards having faces with different numerical indicia reside in a cavity and may be interchanged by a user. The exposed board face corresponds to the setting of the timer such that one full rotation of the shaft and disk corresponds to the numerical indicia of the exposed board face.

An embodiment of the present invention provides a method for presenting a watch face. The method includes: obtaining first context information and second context information, where the first context information is used to determine a watch face style of the smartwatch, and the second context information is used to indicate dressing information of a user; determining the watch face style of the smartwatch according to the first context information; and presenting a watch face pattern of the smartwatch according to the watch face style and the second context information.
