■ 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.
How to charge the watch ･････ P.108
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.)

■ 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
Condition
When the watch is exposed to a state without receiving
an adequate light source for 72 hours or longer.
When the watch is in an insufficient
charging state for a long time.
Situation
How to handle
the situation
When the watch is exposed to an adequate light source
for five seconds or longer, it displays the current time
again after the second hand is rapidly advanced.
After sufficiently charging the battery,
set the watch for the current time, if
necessary.
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)
The second hand stops
pointing at the 15-second
position, and the hour and
minute hands also stop. The second hand stops
pointing at the 45-second
position, and the hour and
minute hands also stop.
The watch conducts
automatic radio signal
receiving. The watch does not
conduct automatic radio
signal receiving.

●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.
※ If your watch is rated as non-water
resistant or water resistant for daily
use, do not wash the watch.
→ Performance and type P.112.
Water resistance P.113.
●Turn the crown from time to time
・ In 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
