How to set date
(1) Pull the crown out to the 1st click position.
(2) Turn the crown to set the date.
(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.
- Do not set the date between 9:00 p.m. and 1:00 a.m..
How to set time
(1) Pull the crown out to the 2nd click position when the second hand is at the 12 o'clock position.
(2) Turn the crown to set the hour and minute hands.
Take a.m./p.m. into consideration when setting the hour and minute hands to the desired time.
You can confirm with the 24 hour hand.
(3) Push the crown back to the normal position.
- The hands be set to the time a few minutes ahead of the current time, taking into consideration the time required to adjust
the stopwatch hands position if necessary.
- When setting the minute hand, advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact time.
- When the stopwatch is measuring, if the crown is pulled out to the 2nd click position, it will automatically reset the
stopwatch hands to "0" position.
Features of the solar watch
Running time
Expected running time from full charge to stoppage will be around 6 months.
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.
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.
When the energy stored in the secondary battery is reduced to an extremely low level, the small 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 1 week.

How to charge and start the watch
Charging 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.
(1) Expose the watch to sunlight or strong artificial light (of more than 1,000 Lx).
When the watch has stopped operating, the small second hand will start moving at two-second intervals.
(2) Keep the watch exposed to the light until the small 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.
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.
- The small 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.
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
℃
