Notes on charging 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:
• Expose the watch with the dial towards direct sunlight for several hours at least once
a month.
• After taking off the watch, put it in a position so that the dial is exposed to bright
light, such as by a window.
• 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).

17
When the watch reaches a low charge state—insufficient charge warning
function
When the power reserve becomes low, the second hand moves once every two
seconds—This is the insufficient charge warning function. Charge the watch by
exposing the dial to light.
• After the watch is charged, the second hand will move normally. See page 18.
• If you have not charged the watch for three days or more since the insufficient
charge warning movement began, the watch will run out power and stop.
Caution
When the second hand moves once every
two seconds, you cannot use any functions—
chronograph, alarm, etc.—except the time indication.
