Analog electronic watch system and analog electronic watch

An analog electronic watch system comprising:

• an analog electronic watch that includes
• a dial plate on which indexes are formed, and
• one or more indicators configured to rotate on the dial plate;
• and
• a terminal appliance that includes
• a communication unit on a terminal side configured to be able to transmit/receive at least time information about time to/from an external appliance,
• an imaging unit configured to image the dial plate, and generate an image of the indicators and the dial plate including an image corresponding to the indicators and the dial plate, and
• a controller on the terminal side configured to detect current display positions of the indicators based on the indexes in the image of the indicators and the dial plate, generate current display time information based on the current display positions, and generate display time correction information based on a difference between the current display time information and watch's internal time information received from the analog electronic watch, wherein
• the controller on the terminal side
• outputs, to the analog electronic watch, a rotation stop signal for stopping rotation of the indicators before performing imaging with the imaging unit,
• detects the current display positions of the indicators within identification areas that are part of the image of the indicators and the dial plate and include the indexes and expected display positions of the indicators based on the watch's internal time information, and
• outputs the display time correction information to the analog electronic watch, and
• the analog electronic watch
• stops the rotation of the indicators based on the rotation stop signal, and
• corrects display positions of the indicators based on the display time correction information.
