Method For Controlling Electronic Watch And Electronic Watch

A method for controlling an electronic watch, the electronic watch comprising:

• a motor configured to drive a hand;
• a first polarity storage device configured to store first polarity information;
• a second polarity storage device configured to store second polarity information;
• a first driving circuit configured to output, to the motor, a first motor drive signal having a polarity corresponding to the first polarity information;
• a second driving circuit configured to output, to the motor, a second motor drive signal having a polarity corresponding to the second polarity information, and
• a control device configured to perform switching between first control processing and second control processing,
• the method comprising:
• when performing the first control processing switching from the second control processing,
• matching the first polarity information with the second polarity information,
• operating the first driving circuit to output the first motor drive signal, and
• rewriting the first polarity information in accordance with an output of the first motor drive signal, and
• when performing the second control processing switching from the first control processing,
• matching the second polarity information with the first polarity information,
• operating the second driving circuit to output the second motor drive signal, and
• rewriting the second polarity information in accordance with an output of the second motor drive signal.

An electronic watch, comprising:

• a motor configured to drive a hand;
• a first polarity storage device configured to store first polarity information;
• a second polarity storage device configured to store second polarity information;
• a first driving circuit configured to output, to the motor, a first motor drive signal having a polarity corresponding to the first polarity information;
• a second driving circuit configured to output, to the motor, a second motor drive signal having a polarity corresponding to the second polarity information;
• a first communication device;
• a second communication device configured to communicate with the first communication device;
• and
• a control device configured to perform switching between processing for operating the first driving circuit to output the first motor drive signal, and rewriting the first polarity information in accordance with an output of the first motor drive signal, and processing for operating the second driving circuit to output the second motor drive signal, and rewriting the second polarity information in accordance with an output of the second motor drive signal, wherein
• the control device performs
• processing for transmitting the second polarity information to the first communication device by the second communication device, and matching the first polarity information stored in the first polarity storage device with the second polarity information based on the second polarity information received by the first communication device, and
• processing for transmitting the first polarity information output by the first communication device to the second communication device, and matching the second polarity information stored in the second polarity storage device with the first polarity information based on the first polarity information received by the second communication device.
