Abstract: The manufacturing process produces a part (10), from a micromachinable material, the part (10) forming a blank of the timepiece component and comprising at least one surface having an initial roughness. It comprises a step of mechanical strengthening treatment of the part in an etching fluid intended to decrease the roughness of said surface. For example, a substrate of said micromachinable material is provided; the substrate is at least partially covered with a protective coating containing at least one aperture; the substrate is etched through the aperture in the protective coating and an etched surface is thus obtained; the mechanical strengthening treatment is applied to said etched surface through the aperture in the protective coating; and then the protective coating is removed. The etching fluid may be a plasma or a liquid chemical etchant.

Abstract: Timepiece component based on a micromachinable material, including at least one micromachinable-material surface portion that is smoothed at least by hydrogen smoothing. The at least one micromachinable-material surface portion includes an oxide layer of thickness larger than 1 micron in order to increase its mechanical strength. In a particular embodiment the micromachinable material can be silicon and the oxide layer silicon oxide.
