Subtractive manufacturing of an oversized MIM blank

A method of making metal component parts for a watch, including one or more types of metal component parts being one or more of i) a casing, ii) a bezel, iii) a buckle, or iv) parts for a watch band, with a Metal Injection Molding (MIM) process, comprising:

• making a first instance of a first type of metal component part for a first watch design derived from a first instance of a MIM blank formed from an injection molding tool, in which at least a portion of the first instance of the MIM blank formed for the first type of metal component part is removed in accordance with a first Computer Numerical Control (CNC) sequence of a subtractive CNC milling process to form an interim shape and geometry of the first instance of the first type of component part for a first watch design;
• and
• making a second instance of the first type of metal component part for a second watch design derived from a second instance of the MIM blank, in which at least a portion of the second instance of the MIM blank formed for the first type of metal component part is removed in accordance with a second CNC sequence of the subtractive CNC milling process to form an interim shape and geometry of the second instance of the first type of component part for a second watch design different than the first watch design,
• wherein the subtractive CNC milling process is applied to both the first instance of the MIM blank for the first type of component part when the first instance of the MIM blank has not yet been sintered and hardened to a finished shape and geometry of the first instance of the first type of metal component part for the first watch design and the second instance of the MIM blank for the first type of component part when the second instance of the MIM blank has not yet been sintered and hardened to a finished shape and geometry of the second instance of the first type of metal component part for the second watch design.
