CHRONOGRAPH
Model No. BL5XXX
Cal. E81*

1. Features

This watch is a solar powered watch that contains a
solar cell in its face that drives the watch by
converting light energy into electrical energy. It is
equipped with numerous functions including a full
auto calendar that changes the date automatically
(day, month and year change through February 28,
2100 including leap years), a daily alarm function
that can be set based on a 24-hour clock, and a
chronograph function that allows measurement of
time in 1/20 second units up to 59 minutes, 59.95
seconds.

2. Before Using

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 9 months without
additional charging (when the power save feature is
operating).

Power Save Feature

When power generation stops as a result of light not
shining on the solar cell during the time display or
local time display, the second hand stops at the
12:00 position and only the hour and minute hands
move to save power. When light once again begins
to shine on the solar cell, the second hand
advances rapidly to the current seconds and returns
to moving at one second intervals.

Proper Use Of This Watch

To use this watch comfortably, make sure to
recharge it before it stops running completely. Since
there is no risk of overcharging (Overcharging
Prevention Feature), it is recommended that the
watch be recharged every day.
