摘要： In the first aspect of the invention, there is provided a wristwatch case having a pipe joined and fixed thereto, the wristwatch case and the pipe having substantially no junction interface. A method of fixing a pipe to a wrist watch case for obtaining this structure comprises the steps of providing a wristwatch case with a through-hole; press fitting a pipe exhibiting a through-hole/pipe press-fit overlap width (namely, outside diameter of the pipe minus diameter of the through-hole) of greater than 0 mm in the through-hole; and heating the wristwatch case after the press fitting. In the second aspect of the invention, there is provided a wristwatch case having a pipe, the wristwatch case and the pipe joined and fixed to each other through a diffusion layer. A method of fixing a pipe to a wristwatch case for obtaining this structure comprises the steps of providing a wristwatch case with a through-hole; press fitting a pipe having its surface furnished with a metallic coating, which exhibits a through-hole/pipe press-fit overlap width (namely, outside diameter of the pipe having its surface furnished with a metallic coating minus diameter of the through-hole) of not less than 0 mm, in the through-hole; and heating the wristwatch case after the press fitting in vacuum or a reducing gas.

摘要翻译： 在本发明的第一方面中，提供了一种具有连接并固定在其上的管的手表壳，手表壳和管基本上没有接合界面。 为了获得这种结构，将管固定到手表壳体上的方法包括以下步骤：向手表壳体提供通孔; 在贯通孔中压配配置有贯穿孔/管压配合重叠宽度（即，管的直径减去通孔直径）大于0mm的管; 并在压配合后加热手表外壳。 在本发明的第二方面中，提供了一种手表壳体，其具有管，手表壳和管通过扩散层接合并彼此固定。 为了获得这种结构，将管固定到手表壳体上的方法包括以下步骤：提供具有通孔的手表外壳; 压配合其表面配有金属涂层的管道，其表现出通孔/管压配合重叠宽度（即管表面的外径设有金属涂层减去通孔直径） 不小于0毫米; 并且在将压力安装在真空或还原气体中之后加热手表外壳。
