Hand movement control device, electronic timepiece, hand movement control method, and storage medium

A hand movement control method comprising, in a case of causing a hand to perform a display operation synchronized with time, outputting, to a driver, a signal to cause the hand to perform a rotational movement by a unit angle per unit period obtained by dividing a reference period by an integer of two or more,

• wherein the signal includes a first signal to cause the driver to cause the hand to perform the rotational movement each time the reference period elapses based on a current time measured by a timing module, and a second signal to cause the driver to cause the hand to perform the rotational movement each time the unit period elapses from a timing of the rotational movement caused by the first signal, and
• wherein the hand movement control method further comprises, in a case of causing the hand to move to a position corresponding to the current time and start the display operation, causing the hand to move to a position corresponding to a first point in time that is ahead of the current time and in units of the reference period and starting controlling the display operation from the first point in time.

A non-transitory computer-readable storage medium storing a program causing, of an electronic timepiece including a hand, a driver that causes the hand to perform a rotational movement by a unit angle, and a timing module that measures a current time, a computer to, in a case of causing a hand to perform a display operation synchronized with time, output, to a driver, a signal to cause the hand to perform a rotational movement by a unit angle per unit period obtained by dividing a reference period by an integer of two or more,

• wherein the signal includes a first signal to cause the driver to cause the hand to perform the rotational movement each time the reference period elapses based on a current time measured by a timing module, and a second signal to cause the driver to cause the hand to perform the rotational movement each time the unit period elapses from a timing of the rotational movement caused by the first signal, and
• wherein the program further causes the computer to, in a case of causing the hand to move to a position corresponding to the current time and start the display operation, cause the hand to move to a position corresponding to a first point in time that is ahead of the current time and in units of the reference period and start controlling the display operation from the first point in time.
