A method for fabrication of a composite component including a first material containing steel 316L and a second material containing zirconia powder formed in a single sintering. The method for fabrication includes: a) forming a first injection molding composition including steel 316L powder and a second injection molding composition including zirconia powder; b) agglomerating via injection molding one of the first and second compositions to form at least a first part of a blank; c) agglomerating by injection molding the other of the first and second materials against the first part of the blank to form at least a second part of the blank; and d) non-consecutively sintering the first and second compositions forming the blank to obtain the composite component formed of steel 316L and zirconia.

A timepiece incudes a crown (4) housed in a cavity (10) provided in the case and open towards the outside, such as a cavity (10) in the side wall of the case (1) of a wristwatch, in the rest position of the crown (4). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (5). The knurling-roller (5) is coupled to a tube (15) wherein is inserted a crown body (18) integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (18). The tube displaces the crown in an axial direction without rotating the crown around its central axis (6). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller (5) without having to manually pull the crown outwards.

Provided is a multicolour cermet and/or ceramic article, and in particular a bezel of a timepiece, made by a method for injecting at least two materials of distinct colours, said article comprising a relief decoration of a colour different from the rest of the article, said decoration being made by laser ablation after injection of the two materials.

To prevent an erroneous operation and improve operability, a button device and a timepiece including the button device are provided. The button device includes: a cylindrical first guide protector 11 protruding from the lateral face of a wristwatch case 1; and a first button 12 disposed in the first guide protector 11 to be slidable inward and outward of the wristwatch case 1. The first button 12 includes a first button head 13 disposed in the first guide protector 11, and a first button shaft 15 passing through a first through hole 14 of the wristwatch case 1. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1. The first guide protector 11 protects the outer periphery of the first button head 13, and this prevents accidental and erroneous operation of the first button 12. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1, and this allows the user to easily place a fingertip on the outer end face of the first button head 13, and so improves the operability of the first button 12.

A consumer product that is a portable and, in some cases, a wearable electronic device. The wearable electronic device may have functionalities including: keeping time; monitoring a user's physiological signals and providing health-related information based on those signals; communicating with other electronic devices or services; visually depicting data on a display; gather data form one or more sensors that may be used to initiate, control, or modify operations of the device; determine a location of a touch on a surface of the device and/or an amount of force exerted on the device, and use either or both as input.

A device for adjusting horological functions of a timepiece, including a mechanism for selection and actuation, including: a drive driving a driving pinion in the clockwise and anti-clockwise directions, a driven pinion driven when the driving pinion turns clockwise and anti-clockwise, the driven pinion moving into a first position by the driving pinion turning clockwise, in which the driven pinion actuates an actuator of a first horological function, and moving into a second position by the driving pinion turning anti-clockwise, in which second position, the driven pinion actuates an actuator of a second horological function, the driven pinion not actuating the actuator of the first horological function when it is in its second position, and vice versa. The mechanism for selection and actuation includes at least two driven pinions, and the adjusting device includes a control mechanism selectively bringing the driving pinion into engagement with each of the driven pinions.

A timepiece having multiple springs while reducing the plane size of the movement. The timepiece has a first barrel including a first barrel arbor, a first spring, and a first barrel wheel; and a second barrel including a second barrel arbor, a second spring, and a second barrel wheel, disposed to a position not superimposed with the first barrel in a plan view from the axial direction of the first barrel arbor and the second barrel arbor, and having rotation of the first barrel transferred thereto; a planetary gear mechanism having a display pivot that turns in a first direction when rotation of the first ratchet wheel that turns in unison with the first barrel arbor is transferred, and turns in a second direction opposite the first direction when rotation of the second barrel wheel is transferred, and is disposed to a position not superimposed with the first barrel and the second barrel in plan view; and a power reserve wheel train including multiple wheels that transfer rotation of the first ratchet wheel to the planetary gear mechanism, and having one of the multiple wheels axially supported by the second barrel arbor.
