Rotating Compass Bezel

How To Use Compass (Northern Hemisphere)

1. Find the sun’s position in the sky.
2. Holding the watch level, point the hour hand in direction of the sun.
3. Rotate the compass bezel using secondary crown until the South marking is between the hour hand (sun’s position) and 12 o’clock.
4. Once South is set, you can use the rest of the directionals.

NOTES:

• For Southern Hemisphere use “North” marker instead of “South”.
• Watch should be set to standard time, not daylight savings.
• This method can only provide a very general bearing, and should not be relied upon for precise orienteering.
• The Count-Up Bezel and Compass Bezel rotate together

Rotating Count-Up Bezel

How To Use Count-Up Bezel:

1. To track seconds: Align “00” with the chronograph second hand. Start the chronograph function. When stopped the chronograph hand will show elapsed seconds on the bezel.
2. To track minutes: Align “00” with minute hand. Minute hand will show elapsed minutes along bezel separate from any chronograph timing.

NOTES: The Count-Up Bezel and Compass Bezel rotate together

Features of the Solar Movement

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.

1. Running time – Expected running time from full charge to stoppage will be around 6 months.
2. 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 battery nears its end, the small second hand moves at two-second intervals instead of the normal one-second intervals.

How to Charge and Start the Watch

Charging the watch:

1. Expose the watch to sunlight or strong artificial light (of more than 1,000Lx).
2. When the watch has stopped operating, the second hand will start moving at two-second intervals.
3. 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.
4. 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.
5. Keep the watch exposed to the light until the second hand moves at one-second intervals.
6. 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.

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 bright lit place for as long as possible. Make sure that the watch temperature does not exceed 50° Celsius.
