Using the Crown

Depending on the operation you want to perform, pull out the crown to the first or second click and then rotate it.
Important!
To prevent loss of water resistance and/or damage due to impact, be sure to push the crown in to its normal position after you are finished using it.
When pushing the crown back in, take care not to apply too much force.
Fast Forward/Fast Reverse
After pulling out the crown to the first or second
rotating it quickly in succession in either
click, direction will start a fast forward or fast reverse operation. While a fast forward operation is in progress, quickly rotating the crown in succession again will increase the speed even further.
The fast reverse operation speed is fixed and cannot be changed.
Stopping Fast Forward/Fast Reverse
Rotate the crown in the direction opposite that of the ongoing operation or press any button.

Solar Charging

What is solar charging?

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.
Important!
Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under high-temperature conditions like the ones described below.
On the dashboard of a vehicle parked in the sun
an incandescent light bulb or
Near other source of heat
Under direct sunlight or in other hot areas for long periods

If you do not perform any operation for about two minutes after pulling out the crown, crown operations will automatically become disabled. If that happens, push the crown back in and then pull it out again.
While you are wearing the watch, make sure that its face (solar panel) is not blocked from
light by the sleeve of your clothing. Power
the generation efficiency is reduced even when the face of the watch is blocked only partially.

Remaining Charge and Dead Battery

The charge level is indicated by watch hand movement. Functions become disabled as battery power goes low.
Important!
Should battery go low or go dead, expose
the face (solar panel) to light
as soon as possible.
Note
Exposing the battery goes dead will cause the second hand to revolve counterclockwise until it stops at second 57. This indicates charging has started.

Power Saving Function

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the second hand to stop, and the watch will enter Level 1 power saving. If the watch is left in this condition for six or seven days, all hands will stop and the watch will enter Level 2 power saving.
Level 1:
Second hand stops to save power.
Level 2:
All hand movement is stopped to save power (day continues operating).
Note
Note that the watch also may enter the power saving state if its face is blocked from light by your sleeve while you are wearing it.
The watch will enter power saving from the Timekeeping Mode only.
Recovering from Power Saving Operation
Press any button or place the watch in a well­lit area to recover from power saving.

Auto Time Adjustment

The watch’s time and day settings can be configured signal.

Note
Even if you are within the normal reception range of a time signal, reception may be made impossible by the following factors: geographic contours, weather, the season, the time of day, wireless noise. Signals become weaker outside of the smaller circles indicated by dashed lines in the maps above, so
above factors have greater effect
the on signal reception. Though the Honolulu and Anchorage areas (time zones) are outside of the time signal reception range of the watch, reception may be possible when reception conditions are good.
With the AT (AUTO) summer time setting, the watch may not indicate correct time if you are using it in a country or region that is different
the country or region where the
from time calibration signal transmitter is located. This is due to differences in adoption of summer time rules, differences in summer time periods, etc. If this happens, change the city and/or summer time setting so the correct time is displayed.
