About energy
■ Energy depletion forewarning function (Two-second
interval movement and Five-second interval movement)
The energy depletion forewarning function is activated when the energy stored in the watch runs low.
In such a case, the seconds 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.

* Neither the button nor the crown can be operated while the seconds hand moves at two-second or five-second
intervals. (This is not a malfunction.)
* While the seconds hand moves at five-second intervals, the hour and minute hands, as well as the date, stop
operating.
* While the seconds hand moves at five-second intervals, the automatic reception function and manual reception
function will not work. After the watch is charged sufficiently and the seconds hand returns to normal one-second
interval movement, conduct the manual reception of radio signals to set the watch to the correct time. ("Automatic
reception and manual reception" → P.17)

● The watch requires good daily care
• Do not wash the watch when its crown is in 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.
Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and
then soak the watch in the water to wash it.
* If your watch is rated as "Non-water resistant" or "water resistant for daily use," please do not wash the watch.

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

* While the watch is being charged, the seconds hand moves at "Five-second Intervals." During the "Five-second Interval Movement,"
neither the button 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. ("Automatic reception and manual reception" → P.17)
