●

Fast Forward/Fast Reverse

After pulling out the crown, rotating it quickly in succession in either direction will cause the hands to move forward or back at high speed. While the hands are moving forward at high speed, quickly rotating the crown in succession again will increase the speed even further.

●

Stopping Fast Forward/Fast Reverse

Rotate the crown in the direction opposite that of the ongoing operation or press any button.

Note

●

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.

Hand and Day Indicator Movement

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.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from the light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

●

Checking the Charge Level

Immediately after you press (C) to return to the Timekeeping Mode, the day of the week hand will indicate the battery charge level. After a short while, the day of the week hand will return to indicating the current day of the week.

Good (high charge)

Good (medium charge)

Low Battery

●

Remaining Charge and Dead Battery

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

●

Day of the Week and Day Indicator Operation

Changing the day setting of the watch will also cause the day of the week hand to move in conjunction with the day.

●

Day

●

It can take anywhere from about 10 to 40 seconds for the day indicator to change after timekeeping reaches midnight. The day of the week hand will move as the day indicator changes.

●

The day may not be indicated correctly while the watch’s crown is pulled out.

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

—

Near an incandescent light bulb or other source of heat

—

Under direct sunlight or in other hot areas for long periods

Important!

●

Should battery go low or go dead, expose the face (solar panel) to light as soon as possible.

Note

●

Exposing the watch face to light after 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

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 :

Basic timekeeping functions are operational.

Level 2 :

Only the day indicator is operational.

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

Your watch can receive time calibration signals and connect with a phone to obtain information that it uses to adjust its date and time setting.

●

First Use of the Watch

Immediately after purchasing the watch, it will acquire GPS location information and configure a Home City based on your current location.

Acquiring GPS Position Information

Manually

●

Normal Use of the Watch

Your watch automatically receives a time calibration signal or GPS signal (time information) regularly each day and adjusts its time setting. This means its time setting is always accurate without the need for any adjustment by you.

Receiving a Time Information

Automatically Auto Time Calibration Signal Receive

Note the following points that apply while the watch is paired with a phone.

●

The watch does not perform auto receive of time calibration signal or GPS signals (time information).

●

Auto receive of time calibration signal or GPS signals (time information) starts to be performed again after there is no connection between the watch and a phone for more than one day.

Note

●

If the watch is unable to adjust its time setting automatically for some reason, you can trigger a GPS signal receive operation manually.

Time Adjustment (GPS,

Time Calibration

Signal)

The watch’s time, day, and Home City settings can be configured in accordance with a received GPS signal or time calibration signal.

●

GPS signal (location information): Used to update Home City, time, and day settings.

●

GPS signal time information: Used to update time and day settings.

●

Time calibration signal: Used to update time and day settings.

Important!

●

Before trying to receive GPS signal time information and/or a time calibration signal, first use GPS to acquire location information and configure Home Time settings.

●

The watch will normally not perform auto signal receive while it is paired with a phone. However, auto receive will be performed if there is no connection between the watch and phone for more than one day.

●

Put the watch into the Airplane Mode whenever you are inside an aircraft or in any other area where radio wave reception is prohibited or restricted.

Using the Watch in a Medical

Facility or Aircraft

Note

●

Areas where time calibration signal reception is supported are limited. When the watch in an area where time calibration signal reception is not supported, adjust time and day settings based on GPS signals.

Acquiring GPS Position Information Manually

You can use a button operation to acquire GPS location information and adjust your Home City, time, and day settings in accordance with your current location.

Note

●

GPS signal reception requires large amounts of power. Perform it only when necessary.

Getting ready

Enter the Timekeeping Mode.

Navigating Between Modes

Move to a location appropriate for signal

reception and orient the watch so its display is pointed straight up at the sky.

Hold down (B) for at least 1.5 seconds.

Release the button as soon as the second hand points to “T(TIME)”.

●

The second hand will move in the following sequence: “Y(YES)” or

“N(NO)” n “T(TIME)”.

Press (B).

This will cause the second hand to move to “T+P”, indicating that location information acquisition has started. The position of the second hand during reception will depend on the current reception conditions.

●

If location information acquisition is successful, the second hand will move to “Y(YES)” and then the watch will automatically adjust its time and day settings. The watch will display the acquired Home City and the day of the week hand will indicate the approximate latitude of your current location.

●

If position information acquisition fails for some reason, the second hand will move to “N(NO)” and then the watch will indicate the current time and day without adjusting them.

Note

●

Reception takes anywhere from about 30 to 80 seconds.

●

It can take as long as 13 minutes when leap second information is included.

●

You may experience location information acquisition problems when you are in the vicinity of a city borderline. The watch’s time and day will not be indicated correctly if the Home City setting is not right for your location. If this happens, move to a location near the center of the city you want to set as your Home City and acquired location information again. Or you can perform a time information receive operation to adjust time and day settings after configuring Home City and summer time settings manually.
