Abstract: Method of manufacturing a watch component (10) for a timepiece, wherein it comprises a first stage of manufacturing a watch component (10) comprising a first surface (1), in which there is arranged at least one recess (20), that is to say a surface recessed from the first surface (1), and wherein it comprises a second finishing stage the watch component, leading to a change in the surface condition, more particularly the roughness, more particularly measured by the parameters Ra and/or Str, and/or the gloss, of the first surface (1) but not of the at least one recess (20) or of a portion exclusively of this at least one recess (20).

Abstract: A horology component (1) for a timepiece, including a first portion (10) and a second portion (20), the first portion (10) comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (20), this second portion (20) taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).

Abstract: Provided is a method for protecting a complex watch component against gaseous environment, characterized in that the entire surface of the complex watch component or parts of said surface is/are coated with a protective coating, which is not visible by observation with the naked eye, by atomic layer deposition (ALD). Further provided are a method for obtaining a complex watch component, and a complex watch component comprising a protective ALD coating.

Abstract: A transparent timepiece component, in particular a watch glass, has a substantially planar or curved interior surface, and has mainly a transparent material colored by a zone of modified chemical composition within the component through an introduction of at least one coloring chemical element of the transparent material, this zone of modified chemical composition extending in one part only of the total thickness of the timepiece component.

Abstract: A horology component (1) for a timepiece, wherein said component comprises a first portion (10) and a second portion (20), the first portion (10) comprising a part that is made from at least one opaque material at least partially superposed on top of the second portion (20), this second portion (20) comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and said part of the first portion (10) comprising structuring (13) allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).
