is watch has a rechargeable cell which is charged by exposing the dial to light,
such as direct sunlight or uorescent lamps.
Aer taking o the watch, put it in a location where the dial is exposed to bright
light, such as by a window.
e watch can be charged eectively when the dial
is exposed to sunlight as shown in the gure.
For optimal performance, be sure to:
• Charge the watch by exposing it to direct sunlight for
five to six hours at least once a month.
• Avoid leaving the watch in a dark place for long periods
of time.
Charging your watch
• If the watch is obscured from light by long sleeves frequently, supplemental charging
may be needed to ensure continual operation.
• Do not charge the watch at high temperature (about 60°C/140°F or higher).

■When the watch reaches a low charge state
(insuffi cient charge warning function)
When the watch reaches a low charge state, the insucient charge warning
function kicks in, and the second hand begins to move in two-second
increments (two-second mode). Charge the watch by exposing its dial to light.
• Aer some time of charging, the second hand will begin to move in onesecond
increments (normal mode).
• If the watch is le in two-second mode for three days or longer, the watch will
run out of power and stop working.
• e time and date are indicated even during
two-second mode.
• Make sure that the watch is charged and
moving in one-second increments (normal
mode) before setting or adjusting the watch.
• While the insucient charge warning
function is active, the compensation
mechanism to ensure timekeeping accuracy
remains disabled. Promptly charge the watch.

• When the battery is fully charged, the overcharge protection function stops the charging so that the
watch performance and rechargeable cell are not adversely aff ected by overcharge.
Your watch will run for approximately 7 months from a full charge or up to 1.5 years with the power
save feature engaged (based on a full charge).
After the second hand starts moving once every two seconds, it will last for approximately 3 days.
Charging your watch

■Power save feature
If you store the watch inside the case or other dark places where no light can
reach the dial of the watch for seven consecutive days or longer, the watch
will automatically stop at the 12 o'clock position to save battery power. In the
meantime, the time is kept internally, whereas the date and power reserve
indicators continue to work normally.
• e power save feature does not work while the crown is at Position 1or Position 2.
• e power save feature cannot be activated manually.
■To cancel the power save feature
Once the dial of the watch is exposed to light and the battery begins to charge,
power save mode will be cancelled, and the hands will move to point to the current
time. Do not pull the crown out while the power save mode is being cancelled and
the hour, minute, and second hands are moving to point to the current time.
Pulling the crown out causes the hands to stop moving at that moment,
preventing them from pointing correctly to the current time.
