The invention relates to a method of manufacturing of a watch component, comprising the steps consisting in: (10) forming a blank (200E1), particularly by injection, including at least one base surface (210) and at least one projecting portion (220) projecting from the base surface (210), (20) forming at least one coating layer (250) covering at least a part of the base surface (210) and/or over at least a part of the projecting portion (220), (30) removing by laser ablation at least a part of said at least one coating layer (250). (40) texturing by laser processing at least a part of the base surface (210) and/or at least a part of the projecting portion (220), and/or at least a part of the at least one coating layer (250).

A method of fabricating a component for use in a watch includes a step of depositing a first thin film on a wafer wherein the first thin film is adapted to allow light reflected away from the wafer to be indicative of a first color characteristic. The step of depositing the first thin film is performed by using a plasma-enhanced chemical vapor deposition process or a low pressure chemical vapor deposition process. The method may further include a step of fabricating a second color characteristic, including defining a pattern on the first thin film using photolithography, and, processing a region within a boundary of the pattern so that the region is adapted to allow light reflected away from the wafer to be indicative of the second color characteristic. The step of processing the region within the boundary of the pattern includes depositing a metal or a ceramic material within the boundary of the pattern which is indicative of the second color characteristic. The step of processing the region within the boundary of the pattern may also include depositing a second thin film within the region within the boundary of the pattern.
