Strengthened timepiece component

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 in...

Zusammenfassung:	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.
