Before using the watch...
Expose the watch to light.
Your watch runs on electrical power generated from light, which is
stored by a chargeable battery. Long-term storage of the watch can
cause the battery to run low, so be sure to expose the watch to light
before using it for the first time. See “Solar Charging” for more
information.
Low Battery Alert
When secondary battery power is low, the second hand of the watch
will jump at 2-second intervals to let you know that charging is
required.
• See “Low Battery Alert” for more information.

Power Saving
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.
• Though the hands are stopped, the watch continues to keep time
internally.
• 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
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.
In Sleep Level 1:
• The second hand is stopped.
• The hour hand, 24-hour hand, minute hand, and day indicator
continue to operate normally.
• Auto Receive is performed normally.
Sleep Level 2
Sleep Level 2 is triggered whenever the watch is left in the dark
while in Sleep Level 1 for six or seven days.
In Sleep Level 2:
• The hour hand, 24-hour hand, and minute hand are stopped.
• If the watch reaches Sleep Level 2 while in the World Time Mode,
the hands will move to 12 o’clock and stop when the Home City
time (kept internally) reaches midnight.
• Auto Receive is disabled.
• The day indicator continues to operate normally.
