A timepiece with a double-sided display, including a first display member and a second display member coaxial to the first display member and integral therewith with a first common arbor. The centers of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis. The first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back.

A horological display mechanism with an elastic hand (1) for driving, about a shaft (D), pipes mounted at the ends of a flexible blade (3), arranged to deform the flexible blade (3), including a mechanism acting on the drive train of the first pipe (2) and of the second pipe (4) and which includes two planetary wheels (82; 84) for driving the pipes (2; 4), and an input planet-carrier chassis (180) for driving the hand (1), and rotatable with a regulation cam (801), the track (802) of which includes a rising edge and falling edge. An elastic arm (803) has a distal end which cooperates with the track and a rising edge of which raises the elastic arm (803) away from the axis of the cam to consume torque, and a falling edge which makes the elastic arm move back towards the axis to restore torque to the system.

A process for blanking an applique for a watch dial, comprises a step of blanking with a laser beam a first part of the outline of this applique, defining a pointed zone or/and a thin groove of at least a first hollow or/and the point or/and the drawn-out portion of at least a first projecting part, and a step of blanking by means of a stamp a second part of said outline which is complementary with the first part. This hybrid blanking technology makes it possible to obtain appliques having, at the end of the blanking process according to the invention, an outline which defines at least one hollow having a pointed zone or/and a thin groove or/and which defines at least one projecting part forming a point or/and a drawn-out portion with configurations and particular dimensions that cannot be obtained by blanking merely by stamping.

An item made of a material including by weight: a metallic and/or ceramic filler present in a percentage greater than or equal to 50% and less than or equal to 85%, at least one polymer present in a percentage greater than or equal to 15% and less than or equal to 50%, the polymer being bonded to the filler. The polymer can include a hydrogen bond donor which is a group NHx adjacent to a hydrogen bond acceptor which is a group C═O; so as to form a unit —[(C═O)NH]—; and the unit —[(C═O)NH]— representing at least 1% molar of the polymer.

The invention relates to a method which comprises the steps of providing a plate (2) made of a micromachinable material, forming the timepiece component (1) with at least one attachment (3) for keeping the component attached to the rest of the plate (2), by etching the plate (2); and creating, along a desired breakage line of the attachment, a pre-detachment area (4) comprising at least one gap (5) obtained by etching into the body of the plate (2).

A timepiece includes a display unit including a first indicating hand and a dial so as to display a time, in which the dial has a first scale having a number for showing an absolute value of a positive numerical value within a plurality of numerical values indicated by the first indicating hand, a second scale having a number for showing an absolute value of a negative numerical value within the plurality of numerical values, a first sign for showing that the numerical value indicated by the first indicating hand is positive, and a second sign for showing that the indicated numerical value is negative.

The present disclosure provides a timepiece including: an hour hand and a minute hand, a dial in which a cutout portion is formed, a plate member disposed at a back side of the dial, and an auxiliary hand member disposed at a position corresponding to the cutout portion of the dial in plan view as viewed in a direction along an axis of the hour hand and the minute hand, the auxiliary hand member being configured to function as a scale for indicating the time of day, and to indicate information other than the time of day.

A process for producing a part provided with an external element includes: providing an electrically conductive substrate having an upper surface and a raised pattern with a crest on the upper surface; depositing an electrically insulating layer onto the upper surface around the pattern to a thickness less than or equal to the distance between the crest and the upper surface; depositing a metal layer onto the crest by galvanic growth so that the metal layer partly rests on the insulating layer; dissolving the insulating layer; covering an assembly including the substrate and the metal layer with a mass of a base material of the part to form an imprint; separating the mass and the metal layer from the substrate, the mass then exhibiting an external element formed by a recess, the shape of which corresponds to the imprint and the base of which interfaces with the metal layer.

A timepiece display device comprises a timepiece body, a support plate, a timepiece driving module, a rotating optical disc, a magnetic element, a top plate, and a rotating shaft of the timepiece driving module passes through the support plate and connects to the center of the rotating optical disc to drive the rotating optical disc to rotate; a display comprises an annular base mounted in the upper chamber of the timepiece body, a dial mounted inside the annular base, an indicator element placed on the dial and corresponding to the time identifier on the dial, and a crystal covering the upper end of the annular base. The indicator element and the magnetic element are positioned by the magnetic attraction of the magnetic element, and the indicator element moves synchronously with the magnetic element to indicate the time.

A device including a first part and at least a second part to be assembled to the first part, the first part including a body from which an attachment extends, the attachment defining a housing for the second part, for example as a timepiece hand.
