Zusammenfassung:PROBLEM TO BE SOLVED: To provide means, in a watch including an antenna that receives a satellite radio wave, that can ensure a space parallel to the antenna to arrange a component related to an additional function and a component related to an increase in the number of hands, and improves the degree of freedom in design to arrange these components.SOLUTION: A watch 1 comprises: a dial 3; a patch antenna 10; an upper display component 52 toward a visible side from the dial 3; and a lower display component 63 on the back of the dial 3. The watch includes a first component layer 100 in which at least part of a wheel train mechanism driving the upper display component 52 and a motor 53 driving the wheel train mechanism are arranged, and a second component layer 200 that is located between the first component layer 100 and the dial 3 and in which the lower display component 63 and a component driving the lower display component 63 are arranged. The patch antenna 10 is arranged in the second component layer 200 overlapped planarly with metal components arranged in the first component layer 100.SELECTED DRAWING: Figure 3 【課題】衛星電波を受信するアンテナを備えた時計において、アンテナと並列的なスペースを確保して、付加機能に係る部品や多針化に係る部品を配置できるとともに、これらの部品を配置する設計上の自由度を向上させる手段を提供する。【解決手段】文字板3と、パッチアンテナ10と、文字板3よりも視認側の上側表示部品52と、文字板3の背面側の下側表示部品63とを有する時計1であって、上側表示部品52を駆動する輪列機構の少なくとも一部と、該輪列機構を駆動するモータ53と、が配置される第1部品層100と、該第1部品層100と前記文字板3との間に位置して、下側表示部品63及び下側表示部品63の駆動部品が配置される第2部品層200とを有し、パッチアンテナ10は、第1部品層100に配置される金属製の部品と平面的に重ねて第2部品層200に配置される。【選択図】図3
