BEFORE INITIAL USE
POWER SAVE FUNCTION
This watch is powered by electrical energy generated and stored by the built-in
Automatic Generating System. The watch also features the “power save func-
tion,” which automatically stops the hands from moving when the watch is not
in use for a certain period of time to minimize the electrical energy consumption.
When the watch is in power save mode, the hands stop moving but
the built-in IC
continues to calculate the time and calendar.

When the watch is in power save mode, swinging the watch several times will
activate the “time relay function,” which automatically resets the watch hands
to the correct time that has been retained inside the watch.
Do not pull the crown out to the second click position while the watch is in power save mode.
This will cancel the power save function causing the time data retained in the watch to be
erased.
Do not leave the watch with its crown being at the second click position, as the watch
consumes greater energy than it uses while it is in power save mode.
<Remarks on Power Save Function>
When the watch is left untouched for approximately 24 hours (approximately
one day), the power save function is automatically activated.
While the second hand is moving at two-second intervals, the power save function
cannot be activated.
When the power save function is activated, the hour, minute, second and 24-
hour hands will stop moving.
While the watch is in power save mode, the calendar continues to function normally.
When the watch is left untouched in power save mode and if the date does not change
correctly, the stored electrical energy is being depleted. Recharge the watch until the
watch resumes the usual one-second interval movement, and then reset the time and
calendar before starting to wear it again.
When the watch wakes up from power save mode while it is running on extremely low
electrical power, the second hand starts moving at two-second intervals. (Refer to “IF
THE SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS” on page 17.)
