It generates the electric energy to power the watch, utilizing the movement of the arm, and stores it in the KINETIC ELECTRICITY STORAGE UNIT (KINETIC E. S. U. ), which requires no periodical replacement unlike conventional button-type batteries. q Calibre number of your watch Please check the case back of your watch to find its calibre number inscribed on it. As illustrated at right, the calibre number of your watch is the 4-digit number to the left of the hyphen mark. Calibre No. 5M62 -0A00 AQ 4 HOW TO CHARGE AND START THE WATCH English 1 2 3 Swing the watch from side to side. * Swing rhythmically at a rate of twice a second. Charge the KINETIC E. S. U. Set the time/calendar and put on the watch. 5 English NUMBER OF SWINGS AND POWER RESERVE Cal. When the watch stops completely, or if you find the second hand moving at twosecond intervals, swing the watch from side to side at a rate of twice a second. The second hand will start moving at one-second intervals. * It is recommended that the watch be swung further until 2 days of power is reserved. As a guideline of recharging, an additional 350 to 400 swings, about 750 to 800 swings in total (Cal. Turn the rotating bezel to align its " mark with the minute hand. Read the number on the rotating bezel that the minute hand points to. Note: For some models, the rotating bezel rotates only counterclockwise. 12 NOTES FOR USING THE WATCH HOW TO CHARGE AND START THE WATCH q To charge the KINETIC E. S. U. efficiently, swing the watch from side to side, making an arc of about 20 cm. q No additional benefit is obtained by swinging the watch more quickly or with greater vigor. q When the watch is swung, the oscillating weight in the generating system rotates to drive the mechanism. q When the watch has been left untouched for more than one year after it completely stopped, the second hand may not start moving at normal one-second intervals even if the watch is swung the number of times indicated in "NUMBER OF SWINGS AND POWER RESERVE". In this case, swing the watch further until the second hand starts moving at one-second intervals. Even if it is further swung after being fully charged, no malfunction will result. q Some models are equipped with an instant-start function, and the watch may start operating after it is swung several times. q It is not necessary to charge the watch fully, as it is charged automatically while it is worn on your wrist. q Even if the watch is worn on your arm, it will not be charged while your arm is not in motion. English POWER RESERVE INDICATOR q The power reserve indicator provides only a general guideline of the duration within which the watch keeps operating without needing to be charged. [. . . ] q When the second hand moves at two-second intervals, the power reserve is very low and the indicator does not function. 13 q Immediately after the watch is swung to charge the KINETIC E. S. U. , the second hand may not properly indicate the power reserve. q Precaution on see-through case-back models: If your watch has a glass case back, do not expose the case back to strong light such as direct sunlight or an incandescent light at close range, as this may temporarily increase the power consumption of the watch circuit, thus reducing the power reserve in the KINETIC E. S. U. This condition, however, will be corrected when the case back is turned away from the light. English 14 TIME/CALENDAR SETTING q For Cal. If it is necessary to set the calendar during that time period, first change the time to any time outside it, set the calendar and then reset the correct time. [. . . ]
