  • Patent number: 11747770
    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.

  • Patent number: 11194296
    Abstract: An electronic device has a reception device; a display device; an input device; a display controller that controls the display device to display the set time zone data when a first operation of the input device instructing displaying time zone data is detected; a positioning driver that operates the reception device to run a reception process and acquire positioning information when a second operation of the input device instructing starting reception in the navigation mode is detected while time zone data is displayed on the display device; and a time zone setter that sets time zone data based on the acquired positioning information.

  • Publication number: 20190324406
    Abstract: An electronic timepiece that drives a function indicator and a calendar wheel with a single motor, and can return the function indicator to the reference position when the position of the function indicator shifts due to an external disturbance. The electronic timepiece has a function indicator for displaying information other than time; a driver that drives the function indicator; a display member that is driven in conjunction with the function indicator to display information based on time; an indicator position detector configured to detect the function indicator at an indicator position detection position; and a controller that controls the driver and the indicator position detector to execute a function indicator position detection process.

  • Publication number: 20180217557
    Abstract: An electronic timepiece enabling easily changing the time zone is provided. The electronic timepiece includes: an operating means; memory configured to store information related to multiple time zone data indicating a time difference to a reference time, and information related to the set time zone data selected from the multiple time zone data; a time display unit having at least an hour hand and a minute hand, and configured to display time; and a controller configured to execute a time zone correction mode to correct the information related to the time zone data that is set. The controller moves the hour hand and displays time on the time display unit in response to operation of the operating means in the time zone correction mode, and based on time zone data corresponding to the displayed time, corrects information related to the set time zone data.
