An analog display device, including: a display; a processor; and an operation member, wherein the display changes a display content by the movable display performing the movement operation, the processor causes the movable display to perform a fast-forward movement operation and display a plurality of display contents in order in accordance with a first input operation, the processor stops the fast-forward movement operation in accordance with a second input operation, and when the processor causes the movable display to perform the fast-forward movement operation, the processor determines a fast-forward movement speed of the movable display in at least a part of switching between display contents which are adjacent to each other in an order of display to a high movement speed which is larger than an average movement speed of the movable display during a round of display of the plurality of display contents.

A radio timepiece, including: a satellite radio wave receiver; a ground wave receiver; a memory; and a controller, wherein the controller performs area determination operation of determining whether a current position is located within a geographical range where the ground wave receiver is capable of acquiring notice information regarding implementation/non-implementation of the leap second adjustment, when the controller determines that the current position is located within the geographical range, the controller controls the ground wave receiver to acquire the notice information, the controller determines, with the notice information, whether the leap second adjustment is scheduled to be implemented at an implementation candidate timing of the leap second adjustment, and when the controller determines that the leap second adjustment is scheduled to be implemented, the controller changes the leap second correction information at or after the implementation candidate timing.

A control method is provided for an electronic device that has a receiver to receive a satellite signal, and a time display unit to display time. The method includes selecting, by manual operation using a crown or a button, a first time correction processing or a second time correction processing. When the first time correction processing is selected, the control method further includes receiving a satellite signal, acquiring time information based on the received satellite signal, and correcting the displayed time based on the acquired time information. When the second time correction processing is selected, the control method further includes receiving a satellite signal, calculating the position of the electronic device based on satellite orbit information contained in the received satellite signal, and correcting the displayed time based on the calculated position.
