 The areas covered by 

 

x

HONOLULU (HNL) and ANCHORAGE (ANC) are quite far 

from the calibration signal transmitters, so certain conditions may cause reception 
problems.
 When 

 

x

HONOLULU (HNL) or HONG KONG (HKG)  is selected as the Home City, 

only the time and date are adjusted according to the time calibration signal. You 
need to switch manually between standard time and daylight saving time (DST) if 
required. See “To toggle the Home City time between standard time and daylight 
saving time” (page E-36) for information about how to do this.

This watch receives a time calibration signal and updates its time setting accordingly. 
However, when using the watch outside of areas covered by time calibration signals, 
you will have to adjust the settings manually as required. See “Confi guring Current 
Time and Date Settings Manually” (page E-38) for more information.

This section explains how the watch updates its time settings when the city code 
selected as the Home City is in Japan, North America, Europe, or China, and is one 
that supports time calibration signal reception.

To recover from the sleep state
Move the watch to a well-lit area or press any button.

Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a 
certain period in an area where it is dark. The table below shows how watch functions 
are affected by Power Saving.

 There actually are two sleep state levels: “second hand sleep” and “function sleep”.

 The watch will not enter a sleep state between 6:00 a.m. and 9:59 p.m. If the watch

is already in a sleep state when 6:00 a.m. arrives, however, it will remain in the 
sleep state.

 The above exposure times all are for reference only. Actual exposure times depend

on lighting conditions.

Supply” section of the Specifi cations (page E-77).

Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation 
temporarily whenever power suddenly drops below a certain level due to overuse 
of the alarm tone over a short period. Note that all operations are disabled while the 
watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal 
operation after power recovers (in about 15 minutes). Putting the watch in a location 
where it is exposed to light will help power to recover sooner.

 When power drops to Level 3, all functions will be disabled but the watch will 

 

x

continue to keep time internally for about one week. If you recharge the battery 
suffi ciently during this period, the analog hands will move automatically to the 
correct setting and regular timekeeping will resume. After one week, all settings 
(including timekeeping) will be cleared. Recharging the battery will reset all settings 
to their initial factory defaults.

You can get an idea of the watch’s power level by 
observing the movement of the 

x Second Hand in the 

Timekeeping Mode. See “Hand Movement and Function 
Status” (page E-13).
 If the 

x Second Hand is moving normally at one-second 

intervals, power is at Level 1.

Low Battery Alert
 If the 

x Second Hand is moving at two-second intervals, 

power is at Level 2, which is quite low. Expose the watch to 
light as soon as possible so it can charge.

Moves at two-second 
intervals.

 Keep the watch in an area normally exposed to bright light when storing it for long

periods. This helps to ensure that power does not run down.
 Storing the watch for long periods in an area where there is no light or wearing it in 

 

x

such a way that it is blocked from exposure to light can cause power to run down. 
Make sure that the watch is exposed to bright light whenever possible.

The face of the watch is a solar panel that generates power from light. The generated 
power charges a built-in rechargeable battery, which powers watch operations. The 
watch charges whenever it is exposed to light.

Whenever you are not 
wearing the watch, be sure 
to leave it in a location 
where it is exposed to light.

 Best charging 

 

x

performance is achieved 
by exposing the watch to 
light that is as strong as 
possible.

When wearing the watch, 
make sure that its face is 
not blocked from light by the 
sleeve of your clothing.

 The watch may enter a 

 

x

sleep state (page E-16) if 
its face is blocked by your 
sleeve even only partially.
