A proposed device is composed of a smartwatch unit, including at least a display unit of the smartwatch, and a box, including a housing to accommodate the smartwatch. The box has a cover being openable and closeable to cover the display unit, wherein the cover has at least one hole so that a corresponding portion of the display unit is visible to a user when the cover is in closed position, and wherein when the cover is in closed position, the smartwatch unit displays the output of the smartwatch in/on the corresponding portion of the display.

A moving mechanism for a decorative element of a timepiece including a circular drive element arranged to be rotatable about a central axis, the decorative element being mounted on the drive element with an arbor integral with the decorative element and parallel to the central axis, and first device for driving the decorative element in a rotational motion about its own arbor and/or in a translational motion along its own arbor, the first drive device for the decorative element being mounted on the circular drive element and arranged to cooperate with fixed actuation device arranged in the periphery of the circular drive element such that the decorative element rotates about its arbor and/or moves along its arbor while rotating about the central axis.

Horological display mechanism (100) for a timepiece (1000), comprising at least one three-dimensional display support (10), which is arranged for the simultaneous display of at least a first variable on a first three-dimensional display (901) under the action of a first control mechanism, and of a second variable on a second three-dimensional display (902) under the action of a second control mechanism, wherein the first display (901) surrounds the second display (902), or vice-versa, and wherein the first control mechanism and the second control mechanism are capable of being manoeuvred independently of one another, and constitute separate mechanisms, one for controlling the translational motion and the other the rotational motion, or vice-versa.

A watch body and a strap are included. The watch body includes a case body having a cylindrical shape, a movement disposed inside the case body, a cover member covering one opening of the case body, and a case back covering the other opening of the case body and including a transmissive region through which the movement can be visually recognized from the outside and the movement can be visually recognized through the cover member. The strap is attached to the watch body and includes a base facing the case back of the watch body and a strap body coupled to the base. The base includes a decoration at a position overlapping at least a part of the transmissive region, and the decoration can be visually recognized through the cover member.

A watch case (10) comprising a middle (11) to which a crystal (12) and a back (13) are fastened so as to form an internal volume, the watch case (10) including, in the internal volume, an external part component (14) whereon a stack of thin layers (15) comprising a substrate layer (150), a solid-state phase switching layer (151) inserted between a transparent encapsulation layer (152) and a spacing layer (153) separating the phase switching layer (151) from the substrate layer (150) is deposited, the phase switching layer (151) being configured so as to have a refractive index capable of varying under exposure from light rays so as to impart to the stack of thin layers (15) at least two interferential colours.

A method for assembling at least a first element and a second element to form, once assembled, an external component for a portable device, including the steps of: a) making the first element; b) making the second element; c) arranging at least a first groove in the first element and at least a second groove in the second element; d) placing and holding the first and second element end-to-end with at least a third connecting element which is inserted and locked in the first and second grooves.
