Abstract: An aspect of the invention relates to a process for manufacturing a horological or jewellery external part element, including a body made of hard material, inlaid with a decoration made of a second material, where in a first step the body made of the hard material is formed, during this first step or in a second step, a hollow is produced in a face of the body, in a third step, the surface condition of the bottom and/or walls of said hollow is modified to increase the contact area thereof, in a fourth step, this hollow is filled with the second material is a composite material including at least one bio-sourced charged polymer including at least one bio-sourced charged polymer chosen for the wear resistance thereof, to constitute an insert forming a said decoration, in a fifth step, a surface finishing of said insert is performed.

Abstract: There is disclosed a clasp for electrically connecting first (10) and second (10?) antenna elements respectively housed in first (50) and second (50?) strands of a wristband of a portable electronic instrument, this clasp including two parts (1, 2) able to be detached from each other, each electrically connected to one of the antenna elements, and able to be mechanically locked onto each other in order to establish an electric contact between the antenna elements. The first detachable part includes a first clasp element (60) including a first plate (62) extending into the extension of the first wristband strand. The second detachable part includes a second clasp element (70) including a second plate (72) extending into the extension of the second wristband strand and a holding device (73). The second detachable part further includes a third clasp element (75) rotatably mounted on the second clasp element (70) and arranged to lock onto the holding device of the second clasp element.

Abstract: There is disclosed a wristband for a portable electronic instrument including at least a first wristband strand (50) including outer and inner faces and one end (50A) of which is intended to be fixed to a case of said portable electronic instrument, this first wristband strand (50) including, housed between said outer and inner faces, an electric conductor including a conductive plate (10) of elongated shape arranged longitudinally in said first wristband strand (50). The conductive plate (10) includes at least one lug (20) cut into its thickness and bent along a longitudinal line in the direction of one of said outer and inner faces of the first wristband strand (50). The first wristband strand (50) further includes at least one orifice (51) arranged transversely between said outer and inner faces of the first wristband strand (50) and arranged for electrically accessing said at least one lug (20). There is also disclosed a method for manufacturing such a wristband.
