Molding was performed using a molding die whose surfaces other than the inner peripheral surface accommodating the windshield and the timepiece mechanical section (movement) and the lower surface in contact with the arm were mirror-polished in advance. In addition, it was adjusted in advance so that the volume of the blank and the clock side almost matched. The watch side molded in this way is completed by removing the slight burrs generated on the mating surface and opening a wound true hole (not shown) by reaming. Was completed. As shown in the schematic cross-sectional view of FIG. 1, the completed timepiece side has mirror-finished upper surface 11 and side surface 12, and no grinding or polishing was required. Further, the watch side had excellent corrosion resistance, and did not require any anticorrosion coating such as plating.

The produced master alloy was melted by a high frequency melting method and cast into a water-cooled copper mold to obtain a bulk amorphous alloy rod having a cross-sectional shape shown in FIG. 2 and a length of 100 mm. 1. Height from alloy bar
A 17 mm blank was cut out with a diamond cutter. The blank was heated at 440 ° C. (713
K) and formed into a watch band piece by a closed press method. As shown in FIG. 3, each surface was mirror-finished and patterned using a molding die so as to correspond to the outer mirror portion 31 and the inner pattern portion 32. It was adjusted in advance so that the volume of the blank and the watch band piece almost matched. In the watch band piece formed in this way, a small burr generated on the mating surface is removed, and a hole 33 for receiving a connecting pin for connecting the band pieces necessary for completing the watch band is formed by reaming. As a result, the cutting process was minimized. Further, the mirror portion 31 shown in FIG. 3 could be finished without polishing and grinding, and the pattern portion 32 could be finished without patterning.
A plurality of band pieces were connected by inserting connecting pins into holes 41 as shown in FIG. 4 to complete a watch band.
This watch band had excellent corrosion resistance and did not require any anticorrosion coating such as plating.
