1. A method for fabrication of a composite component for a timepiece, the method comprising:
a) forming a first injection molding composition including steel 316L powder and a second injection molding composition including zirconia powder;
b) agglomerating via injection molding one of the first and second injection molding compositions to form at least a first part of a blank;
c) agglomerating by injection molding the other of the first and second injection molding compositions against the first part of the blank to form at least a second part of the blank; and
d) non-consecutively sintering the first and second injection molding compositions forming the blank to obtain the composite component formed of steel 316L and zirconia,
wherein the first part forms a main bezel body of the timepiece having recesses, and the second part is filled in the recesses to form one or more graduations.
