Citizen Calibre 8700 BL8000-03A User Manual page 4

This watch is a solar-powered watch. Please fully charge the watch before
using by exposing it to light by referring to "11. General Reference for
Charging Times".
A secondary battery is used in this watch to store electrical energy. This secondary
battery is a clean energy battery that does not contain mercury or other toxic
substances. Once fully charged, the watch will continue to run for about 1.5 years
without additional charging (when the power save feature is operating).
V Power Save Feature:
When power generation stops as a result of light not shining on the solar cell during
the time (TME) or local time (L-TM) mode, the power save feature is activated and
the second hand stops at the 0 seconds position to save power. The 24 hour hand,
hour hand and minute hand continue to move normally. When light once again
begins to shine on the solar cell, the power save feature is canceled and the second
hand rapidly moves to the current time and returns to moving at 1-second intervals.
Although varying according to the design, the power save feature is activated
when light does not shine continuously on the solar cell for 30 minutes or more,
and the second hand has reached the 0 seconds position.

<Proper Use of this Watch>
To use this watch comfortably, make sure to charge it before it stops running
completely. Since there is no risk of overcharging no matter how much the watch is
charged (Over Charge Prevention Feature), it is recommended that the watch be
charged every day.
