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-28) 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.

x

 The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration 
signal transmitters, so certain conditions may cause reception problems.

 For details about the operating time and daily operating conditions, see the “Power Supply” section of 
the Specifi cations (page E-55).

 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.

Approximately 1 week

 

x

 All hands stopped at 12 o’clock

 

x

 Internal timekeeping maintained

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

 

x

 When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the 
battery will reset all settings to their initial factory defaults, so you will need to confi gure settings again.

 

x

 When the watch is at Level 3, exposing it to light for a while will cause the 

x Second Hand to move to 

the position of second 57. This indicates that charging has started.

 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 continuous signal reception, or overuse of the alarm 
tone over a short period or other operations 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. Putting the watch in a location where it is exposed to light will help power to recover sooner.

 The above times are for reference only. Actual times depend on lighting conditions.

 

x

 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.

 

x

 Storing the watch for long periods in an area where there is no light or wearing it in 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.

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

x Second Hand.

 

x

 If the 

x Second Hand is moving normally at one-second intervals, power is 

at Level 1.

 

x

 If the 

x Second Hand is moving at two-second intervals, power is at Level 2, 

which is quite low (Low battery alert). Expose the watch to light as soon as 
possible so it can charge.

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.

 

x

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

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

 

x

 The watch may enter a sleep 
state (page E-13) if its face is 
blocked by your sleeve even 
only partially.
