1. Starting your wristwatch
For rapid charging, you should hold your wristwatch in bright light
(e. g. sunlight or neon light).
The time required to charge your wristwatch depends on the intensity of
the light source. As a guide, the following tables contain approximate
charging times. Please note that, to avoid damage, your watch must not
be exposed to temperatures below – 5°C or above + 50°C.
Important: Never hold your solar wristwatch too near to light sources
which give off heat! Do not leave your watch in direct sunlight for long
periods of time. Temperatures above 50°C may cause damage.
GB xCharging times may vary slightly from watch to watch. We recom-
mend charging your solar wristwatch a little each day to avoid the
energy store running down completely.
xNormal daylight is sufficient for continuous operation of your solar
wristwatch. Avoid covering the dial completely with your sleeve, as
otherwise no light can reach it.
xWhen the energy store is fully charged, your solar wristwatch will
run for at least 2 months even in darkness.
xIf you do not wear your solar wirstwatch, you should keep it in a
light place to ensure that it is always ready for use.

turning the crown.
To ensure that the date display
changes at midnight and not
at 12 noon, please observe
the following points when
setting your watch:
xSet the date display to yesterday’s date.
xThen move the hands forward until today’s date is displayed.
xThen set the correct time, bearing in mind whether it is between AM
00:00 h and 12:00 h or between PM 12:00 and 24:00 h.

2.2.4. Charge level indication for solar wristwatches without second
hand and date
xIf your solar wristwatch is running out of energy, the following
charge level indication will commence.
xThe minute hand begins to move in a 10-second rhythm (6 steps) per
minute. Your solar wristwatch will nevertheless continue to run for
approx. 2 Weeks and still show the exact time.
3. Technical information that is interesting for you
xYour wristwatch draws its energy from sunlight or artificial light.
The integrated solar cell converts the light into electrical energy, which
supplies the quartz movement.
xEven if you do not use your watch for a long period, it will still
recharge itself when held in the light.
xThe innovative energy store ensures that your solar wristwatch keeps
running in half-light and even in darkness.
xThe hight-performance energy store which performs this function has
an almost unlimited life at full output capacity.
xDo not under any circumstances replace the energy store with a
conventional silver-oxide battery, as this may cause damage to your
solar wristwatch.
xTo ensure a long service life, you should take your solar wirstwatch
to a watch specialist every 3 years to have it tested for water resistance
and the oil level in the wheel train.
xPlease make sure that your solar wristwatch is not subjected to heavy
blows or extreme temperatures. Otherwise, damage may be caused to
the high-precision electronic circuit, the miniature stepping motor and
the solar cell.

5. Important additional information for if your solar wristwatch stops.
x Please check whether the crown (winder) has been pulled out. If so,
press it back in, your solar wristwatch will then start running again.
x If your solar wristwatch does not run even with the crown pressd in:
Your watch has not received enough light. Put it in a bright place (sun-
light or neon light). It will then start up as soon as the energy store has
been sufficiently charged. The time required for this varies according to
the light intensity and the model of watch. A guide to charging times is
given in the corresponding tables.
x If the date has not changed: Have you set your watch to the correct
time of day? Please follow the procedure described in Section 2.1.1.
