A method for calibrating a light smart watch includes: providing an FPC soft board under a dial, a size of the FPC soft board matching a size of the dial, the FPC soft board is divided into a plurality of partitions, each partition is insulated from other partitions, and each of watch hands and each partition form a capacitor in turn when the watch hands run; detecting a capacitance change amount of each partition, determining positions of partitions where the watch hands are currently located, and determining a current time indicated by the watch hands, according to the positions of partitions where the watch hands are currently located; comparing the current time indicated by the watch hands with a current time of a mobile terminal to determine a time error; and adjusting the watch hands, according to the time error to run in sync with the time of the mobile terminal.

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.

An electronic watch of the present disclosure includes a power generation device having a rotating weight rotating about a rotary shaft, and configured to convert mechanical energy obtained by rotation of the rotating weight into electrical energy, a clocking device configured to clock time, and an antenna disposed on an inner side in a radial direction of the rotating weight than a rotational trajectory of an outer peripheral edge of the rotating weight in plan view viewed from an axial direction of the rotary shaft, and configured to be capable of receiving a long wave standard radio wave, wherein the rotating weight has an opening portion or a notch portion disposed at a position that enables the rotating weight to overlap with the antenna in plan view, and does not cover the entire antenna in plan view regardless of a rotational position.
