An inlaid timepiece component (1) including a body (10) made of a metallic and/or ceramic material including at least one hollow (11) forming the impression of a decoration (12). The at least one hollow is completely filled with successive strata (13, 14, 15) formed by an agglomeration of particles (16) via a cold metallisation in order to form a timepiece component (1) inlaid with at least one decoration (12).

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.

A method is for manufacturing a part including a support made of an electrically non-conductive material, the support being provided with at least one recess filled with an aesthetic element made of an electrically conductive material, and the aesthetic element forms a decoration on a side of the part that is intended to be visible. The method includes inlaying by pressing a preform intended to form the aesthetic element into the at least one recess of the support, and treating the surface of the aesthetic element. The at least one recess opens in one or more places onto a side of the part that is intended to be non-visible, to respectively form one or more contact points for carrying current across the aesthetic element during the surface treatment.

In a plan view in an axial direction of an indicating hand axle of a small second hand, three arrangement relationships described below are satisfied between a 10 o'clock side information display unit and an hour hand. According to a first arrangement relationship, respective numbers of a scale are disposed line-symmetrically with respect to a virtual straight line connecting a scale and the indicating hand axle to each other. According to a second arrangement relationship, the indicating hand axle is located at a position which does not overlap an indicating hand axle of the hour hand. According to a third arrangement relationship, a portion of a rotatable range of the hour hand overlaps a rotatable range of the small second hand, and does not overlap the scale.
