Zusammenfassung:	Each type of metal component part for two or more watch designs can be derived from instances of that corresponding type of MIM blank for that component part, which is formed from a same injection molding tool (respectively for each type of component part). An example instance of the MIM blank formed for a type of component part then has at least a portion of the instance of the MIM blank subtracted through a CNC milling process to form an interim shape and geometry of an instance of the type of component part for a given watch design. The CNC milling process can be applied to the MIM blank for that component part when the MIM blank is in its interim shape and geometry and has not yet been hardened to a finished shape and geometry of an instance of that type of component part for the watch design.
