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.
– 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.
(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.
– The 24 hour hand moves correspondingly with the hour hand.
– When setting the hour hand, check that the 24 hour hand is correctly set.
– 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.
(3) Push the crown back to the normal position.
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 changes 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.
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℃
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.
Guidelines for charging time
The below table provides only general guidelines.

Condition A : Time required for full charge
Condition B : Time required for steady operation
Condition C : Time required for 1 day’s charge
(*) The values in this column represent the charging times required until the second hand moves constantly at one-second intervals after the watch starts operating with the second hand moving at two-second intervals.
Even if the watch is not charged for the time specified in the column, the second hand may temporarily move at one-second intervals. But it will soon resume moving at two-second intervals; therefore, charge the watch for more than the specified period.
How to use stopwatch function
- The stopwatch can measure up to 29’59” in one-second increasements.
- When the measurement reaches 30 minutes, the stopwatch automatically stops counting.

- The stopwatch second hand is capable of timing 30 minutes. (60 seconds x 30 times)
- The stopwatch minute hand is capable of timing 30 minutes.
- Before using the stopwatch, be sure to check that the crown is set at the normal position and that the stopwatch hands are reset to the “0” position.
-If the stopwatch hands do not return to the “0” position when the stopwatch is reset to “0”, follow the procedure in “Stopwatch hand position adjustment”.
Stopwatch hand position adjustment
If the stopwatch hands are not in the “0” position, follow the procedures
below to set them.
(1) Pull the crown out to the 2nd click position.
– When the stopwatch is measuring, if the crown is pulled out to the 2nd click
position, it will be automatically reset.
(2) Press the button A or B to set the stopwatch hands to the “0” position.
The movements of the stopwatch minute hand and the stopwatch second hand are
interlocked. To set the stopwatch minute hand to the “0” position, continue to
move the stopwatch second hand until the stopwatch minute hand reaches the “0”
position.
– The stopwatch hands move quickly if the button A or B is kept pressed.
(3) Push the crown back to the normal position.
Guidelines for battery indicator
- Press button B for more than 1 second. The remaining battery capacity is indicated.
- Status indication is 2 seconds. Then it returns automatically.
