Abstract
A timepiece component, such as a balance, an oscillating mass or a wheel, having a structure made according to a micro-manufacturing technique, such as the DRIE technique. The component has at least one member formed in or at the periphery of the structure and made of a material different from that of the structure. This member is typically metal and is formed by electro-forming using a cavity of the structure as a mold.
