Solar cell q Converts light energy into electrical energy, thus powering the watch. Instant-start function q Even when the watch is left uncharged and the rechargeable battery is completely drained, the watch starts operating in a few seconds once exposed to light. Rechargeable battery q Keeps the watch operating for 6 months after full charge. q No need for battery change 3 English DISPLAY AND CROWN Hour hand Minute hand 2 a b c Crown Second hand Date a: Normal position b: First click c: Second click 4 6 The solar cell is installed under the dial. HOW TO CHARGE AND START THE WATCH English TO CHARGE THE WATCH q When you start the watch or when the energy in the rechargeable battery is reduced to an extremely low level, charge it sufficiently by exposing the watch to light. q Instant-start function: When the watch is exposed to sunlight or strong artificial light (of more than 1,000 lux), it will start operating immediately with the second hand moving at 2-second intervals. 1 Expose the watch to sunlight or strong artificial light. 2 * When the watch has stopped operating, the second hand will start moving at 2-second intervals. Keep the watch exposed to the light until the second hand moves at 1second intervals. 3 Set the correct date and time before wearing the watch. * See "CHARGING TIME GUIDELINES" on page 6. 1 5 English CHARGING TIME GUIDELINES Illumination (lux) 500 700 1,000 3,000 5,000 10,000 10,000 100,000 Time required (approx.)

If the watch is not charged for the time specified in the column, the second hand may temporarily move at 1-second intervals. However, as it will soon resume moving at 2-second intervals, you should charge the watch for more than the specified period. English ENERGY DEPLETION FOREWARNING FUNCTION q When the energy stored in the rechargeable battery is reduced to an extremely low level, the second hand starts moving at 2-second intervals instead of the normal 1second intervals. q In that case, recharge the watch as soon as possible by exposing it to light. Otherwise, the watch may stop operating in about 3 days. TO PREVENT THE ENERGY DEPLETION q Wear the watch so that it is not covered by your clothes. q When the watch is not in use, leave it in a bright place as long as possible. NOTE ON POWER SUPPLY q This watch is provided with a rechargeable battery. Unlike conventional batterypowered watches, therefore, battery replacement is not necessary. q The solar cell is an energy source that has less adverse effect on the natural environment than conventional batteries. 7 TIME/CALENDAR SETTING English 1 Set the previous day's date. 2 Turn the hands until the desired date appears. 3 Set the hands to the desired time. 4 Push back the crown completely. 1 « 2 « 4 b c 2 3 a 8 « NOTES FOR USING THE WATCH English HOW TO CHARGE AND START THE WATCH CAUTION Caution for charging q When charging the watch, do not place it too close to a photoflash bulb, spotlight, incandescent light or other light sources as the watch temperature may become extremely high, causing damage to the parts inside the watch. q When exposing the watch to sunlight to charge it, do not leave it on the dashboard of a car, etc. for a long time, as the watch temperature may become extremely high. q While charging the watch, make sure the watch temperature does not exceed 60 C. q When the instant-start function is activated by exposing the watch to light, the second hand starts moving at 2-second intervals immediately, but the energy stored in the rechargeable battery is not sufficient. If the watch is turned away from the light source, it may stop operating. Therefore, please continue to charge the watch. q It is not necessary to charge the watch fully. It is important, however, to charge the watch sufficiently, especially in case of initial charge. NOTE ON POWER SUPPLY CAUTION q Never insert a conventional silver oxide battery in your watch as it may explode, generate an intense heat or catch fire. The watch is so designed that even if a conventional battery is installed in the watch, the watch will not operate. 9 TIME/CALENDER SETTING English 10 q Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, it may not change properly. If it is necessary to set the date during that time period, first change the time to any time outside it, set the date and then reset the correct time. q To set the exact time, pull out the crown to the second click when the second hand is at the 12 o'clock position and push it back in to the normal position in accordance with a time signal. q When setting the hour hand, check that AM/PM is correctly set. The watch is so designed that the date changes once in 24 hours. Turn the hands past the 12 o'clock marker to determine whether the watch is set for the A.M. or P.M. period. If the date changes, the time is set for the A.M. period. If the date does not change, the time is set for the P.M. period. q When setting the minute hand, first advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact minute. q It is necessary to adjust the date at the end of February and 30-day months. q Please set the time and calendar after the second hand starts moving at one-second intervals.
