Recharging your 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
affected 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.

16
For optimal performance
For optimal performance, make sure to observe the following precautions:
•
Place the watch under direct sunlight and charge it for 5 to 6 hours at least once a month.
• After taking off the watch, place it in a well-lighted place or by the window where
sunlight shines in.
• Avoid leaving the watch in a dark place for long periods of time.
If the watch is hidden under clothes and not exposed to light, it cannot be charged
sufficiently.
Do not charge the watch at a high temperature (about 60°C or higher).
When the watch reaches a low charge state (insufficient charge warning function)
2-second
2-second
When the watch reaches a low charge state, the insufficient
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.
• After some time of charging, the second hand will begin to
move in one-second increments (normal mode).
• If the watch is left in two-second mode for three days or
longer, the watch will run out of power and stop working.
•
The time and date are indicated even during two-second mode.
Recharging your watch

17
• Make sure that the watch is charged and moving in one-second increments (normal
mode) before setting or adjusting the watch.
• While the insufficient charge warning function is active, the compensation
mechanism to ensure timekeeping accuracy remains disabled. Promptly charge
the 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 a long period of time, 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.
• The power save feature does not work while the crown is at Position or Position .
• The 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.
