Your watch runs on electrical power generated from light, which is 
stored by a chargeable battery. 
To ensure stable operation, make sure that the watch is exposed to 
light as much as possible. 

•  Whenever you are not wearing the watch on your wrist, position 

it so the face (solar cell) is pointed in the direction of a source of 
bright light. Leave the watch under fl uorescent lighting, near a 
window, etc.

•  When wearing the watch, try to keep your sleeve from blocking its 

face, where the solar cell is located. Charging effi ciency is reduced 
signifi cantly even if the face of the watch is covered only partially 
by your sleeve.

Your watch continues to operate even when it is not exposed to light. 
Leaving the watch in the dark can run down its battery and cause 
functions to become disabled. 

Power Saving causes the watch to enter a sleep state automatically 
and stop movement of the analog hands in order to save power 
whenever the watch is left in the dark. 
The watch will exit the sleep state if you expose it to light or perform 
any button operation. 
•  Note that the watch also may enter the sleep state and stop if the 

solar panel is blocked from light by your sleeve. 

Sleep Level 1 is triggered whenever the watch is left in the dark for 
about one hour any time between the hours of 10 p.m. and 6 a.m. 
•  Second hand stopped

•  The hour, minute, day, and day of the week hands continue to 

operate normally. 

•  Auto Receive is disabled. 

Sleep Level 2 is triggered whenever the watch is left in the dark while 
in Sleep Level 1 for six or seven days. 
•  The hour, minute, day, and day of the week hands stop at their 

current positions. 

•  Auto Receive disabled

•  Digital timekeeping functions continue to operate normally. 

Avoid charging the watch in the following locations, and anywhere 
else where the watch may become very hot. 
•  On the dashboard of an automobile parked in the sun

•  Very close to an incandescent light source or other sources of heat 

•  In a location exposed to direct sunlight for long periods 

 

 

Depending on the light source you are using, the 
case of the watch may become quite hot when 
charging. Take care to guard against burn injury after 
charging.
