A display panel includes a plate-shaped decoration member including a shading part and a light transmission part formed within the shading part, as well as a plate-shaped reflection member disposed on a back side of the decoration member. The shading part and the light transmission part create a fine pattern in plan view. The reflection member is configured to reflect light. The decoration member is disposed on a front surface of the reflection member.

A method for depositing a coating on a substrate (100), including a step of depositing a thin intermetallic layer (110) on the substrate (100), so as to obtain, at the end of this step, an external part (10) having a predetermined final colour.

A method for depositing a coating on a substrate (100), including successively depositing a thin intermetallic layer (110) on the substrate (100), so as to obtain an external part (10), and annealing the external part (10) in a dedicated enclosure.

The invention relates to a timepiece component made of composite material including at least one reinforcement and one matrix, the reinforcement having a three-dimensional honeycomb structure with a plurality of cells into which the matrix is injected. The invention also concerns a method for manufacturing such a timepiece component.

A watch external part of the present invention is equipped with a substrate and a coating formed using an aerosol deposition method. The coating is selectively provided at a portion of a site observable in a state with the watch external part incorporated in a watch. The substrate is made of a material including one type or two or more types selected from a group consisting of sapphire glass, quartz, and plastic. The watch external part is further equipped with a ground layer having at least one layer between the substrate and the coating.
