About energy
■ Energy depletion forewarning function
The energy depletion forewarning function is activated when the energy stored in the
watch runs low. In such a case, the second hand moves at two-second intervals. If
the watch continues to be in the state of two-second interval movement, the watch
switches to five-second interval movement, followed by a completely stopped state.
If the energy depletion forewarning function is activated, charge the watch sufficiently.

Standard charging time ･･･････ P.109

※ Neither the buttons nor the crown can be operated while the second hand moves at two-second or five-sec-
ond intervals (this is not a malfunction).
※ While the second hand moves at five-second intervals, the hour and minute hands, stop operating.
※ While the second hand moves at five-second intervals, the watch is unable to receive radio signals automati-
cally. After the watch is charged sufficiently and the second hand returns to normal one-second interval
movement, conduct the manual reception of radio signals to set the watch to the correct time. (Refer to
Automatic Reception and Manual Reception on P.98.)

Daily care
●The watch requires good daily care
・ Do not wash the watch when its crown is
at the extended position.
・ Wipe away moisture, sweat or dirt with a
soft cloth
・ After soaking the watch in seawater, be
sure to wash the watch in clean pure
water and wipe it dry carefully.
※ I f your watch is rated as non-water
resistant or water resistant for daily
use, do not wash the watch.

●Turn the crown from time to time
・ I n order to prevent corrosion of the
crown, turn the crown from time to time.
・ The same practice should be applied to
a crown. (No need to pull out the screw
lock type crown.) → Crown P.85

■ Power save function
This watch is equipped with a power save function which can suppress energy consump-
tion when it is left without receiving an adequate light source for a certain length of time.
※ There are two types of power save mode.
Power Save 1

Power Save 2
※ While the watch is being charged, the second hand moves at Five-second Intervals.
During the Five-second Interval Movement, neither the buttons nor the crown can be operated.
※ If the Power Save 2 mode is prolonged, the stored power amount drops and the internal current time information stored will be lost.
When the watch returns to its normal movement of one-second interval after sufficiently charging the battery,
set the current time by receiving a radio signal. (Refer to Automatic Reception and Manual Reception → P.98)
