Abstract

See full text

An electronic watch includes a first hand that is rotated by a first motor, and indicates a higher digit of numerical information or time information, a second hand that is rotated by a second motor, and indicates a lower digit of the numerical information or the time information, and a motor controller. The motor controller performs a numerical value indication mode for driving the first motor and the second motor simultaneously to indicate an increase or decrease in the numerical information, or time correction mode for driving the first motor and the second motor simultaneously to correct the time information, and in the numerical value indication mode or the time correction mode, controls a drive frequency of the first motor and a drive frequency of the second motor such that angular velocity of hand movement of the first hand is less than angular velocity of hand movement of the second hand.
