Abstract
PURPOSE: To provide a wider range of design of the portable timepiece case by forming a case of a metal material ready to shape, plating its surface with a noble metal or its alloy as the first coating, and then unitarily bonding it with a band, before plating this with a noble metal or its alloy as the finish coating.
CONSTITUTION: Nickel silver or a copper alloy which is ready to shape, such as brass, is used to form a case, whose surface is plated with a noble metal or its alloy, such as Au, Au-Ni or Au-Co, as the first coating. After that, this is bonded with a band of an austenite stainless steel or Ni-Cr-Mo alloy by brazing or the like. The unitized case and band is plated with a noble metal or its alloy as the finish coating.
