Recharging Your Watch - Citizen E650 User Manual

Recharging your watch

This watch has a rechargeable cell which is charged by exposing the dial to
light such as direct sunlight or fluorescent lamps.
For optimal performance, be sure to keep your watch charged at all times. When
not wearing your watch, place it near a window or other light source to ensure
the dial receives light sufficient for charging.
In addition, to use this watch comfortably, follow the instructions below.
• Expose the watch with the dial facing towards direct outdoors sunlight
(not through a window) for five to six hours at least once a month.
• Before storing the watch in a dark place for an extended period of
time, be sure to charge it fully.
• When the watch is regularly covered with long sleeves, it may not be
charged sufficiently. Try to keep the watch exposed to light sufficient for
charging.
• Do not charge the watch at a high temperature (about 60˚C/140˚F or higher).

that the watch performance and secondary battery are not adversely affected by overcharge.
Your watch will run for approximately 10 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
