摘要： A casing of a radio-controlled wristwatch comprises a casing base body through which a radio wave can transmit, and a thin film covering all or part of an exterior surface of the casing base body and having a surface assuming a metallic color. The casing base body comprises a casing main body portion and a back lid portion, all or a substantial part of the casing main body portion and/or all or a substantial part of the back lid portion being made of a material having a radio wave transmissive property. The material having a radio wave transmissive property consists of a ceramic or glass. The thin film having a surface assuming a metallic color consists of a metal or metallic compound. Thus, it is possible to accommodate not only a watch unit but also an antenna unit in the casing to thereby provide a radio-controlled wristwatch with a built-in antenna that has a luxurious appearance and allows for a greater freedom of design.

摘要翻译： 无线电控制的手表的外壳包括无线电波可以透过的外壳基体，以及覆盖壳体基体的全部或一部分外表面并具有呈金属色的表面的薄膜。 壳体基体包括壳体主体部分和后盖部分，壳体主体部分的全部或主要部分和/或后盖部分的全部或大部分由具有无线电波传播的材料制成 属性。 具有无线电波传播特性的材料由陶瓷或玻璃构成。 具有呈金属色的表面的薄膜由金属或金属化合物构成。 因此，不仅可以容纳手表单元，而且可以容纳壳体中的天线单元，从而提供具有豪华外观并允许更大设计自由度的内置天线的无线电控制手表。
