Abstract

An analog electronic watch includes watch's internal time, and controls rotation of a group of indicators based on the watch's internal time. A terminal appliance stops the rotation of the group of indicators, generates an image of the indicators and the dial plate with an imaging unit, detects current display positions of the group of indicators in identification areas as part of the image of the indicators and the dial plate, generates current display time information based on the current display positions, and generates display time correction information based on a difference between the current display time information and the watch's internal time information. The analog electronic watch corrects the display positions of the group of indicators based on the display time correction information. There are provided an analog electronic watch system and an analog electronic watch that can reduce a time required for display time correction.
