Abstract:
A watch includes an hour hand having a first conductive portion and rotating about an hour hand shaft, a seconds hand having a second conductive portion and rotating at a rotational speed faster than that of the hour hand about a seconds hand shaft, which is coaxial with the hour hand shaft, and a planar inverted-F antenna disposed, in plan view viewed from a direction parallel to the hour hand shaft, at a position overlapping a rotation range of the first conductive portion and a rotation range of the second conductive portion, and receiving a radio wave, and when the planar inverted-F antenna receives a radio wave, a controller, after rotating the seconds hand and then stopping the seconds hand at a reception indication position, rotates the hour hand such that the first conductive portion and the second conductive portion overlap each other in the plan view.
