 How to set date
(1) Pull the crown out to the 1st click position.
(2) Turn the crown to set the date.
- Do not set the date between 9:00 p.m. and 1:00 a.m..
(3) Push the crown back to the normal position.
Tips : When the date change during daytime, it happens when a.m./p.m. is wrongly set. Advance the hour hand by 12 hours.
 Features of the solar watch
This watch is a solar-powered watch containing a solar cell underneath the dial to convert any form of light into
"electrical energy" and store the power in a secondary battery.
Unlike conventional quartz watches, this watch does not use a silver oxide battery, thus eliminating the need
for battery replacement.
 Running time
Expected running time from full charge to stoppage will be around 4 months.
 Over charge prevent function
If the secondary battery is charged more than predetermined voltage, over charge prevent function is
operated to prevent the secondary battery deterioration and breakage.
 Power depletion warning function
When the energy stored in the secondary battery is reduced to an extremely low level, the second hand starts
moving at two-second intervals instead of the normal one-second intervals. In that case, recharge the watch as
soon as possible by exposing it to light. Otherwise, the watch may stop operating in about 2 weeks.
 How to charge and start the watch
 Charging the watch
When you start the watch or when the energy remaining in the secondary battery is very low, charge it
sufficiently by exposing the watch to light.
(1) Expose the watch to sunlight or strong artificial light (of more than 1,000 Lx).
When the watch has stopped operating, the second hand will start moving at two-second intervals.
- The second hand immediately starts moving at two-second intervals, but the energy stored in the secondary battery is not yet
sufficient. If the watch is turned away from the light, it may stop operating.
It is not necessary to charge the watch fully. It is important, however, to charge the watch sufficiently, especially in the case of
initial charging.
(2) Keep the watch exposed to the light until the second hand moves at one-second intervals.
(3) When the watch is charged after it has completely stopped, set the date and time before wearing the
watch.
 Caution
When charging the watch, do not place it too close to fluorescent lamp or other light sources as the watch
temperature will become extremely high, causing damage to the parts inside the watch.
 To prevent energy depletion
• Avoid covering the watch face with your clothing while wearing it.
• When the watch is not in use, leave it in a brightly lit place for as long as possible.
Make sure that the watch temperature does not exceed 50℃.
