Lumibrite If your watch has Lumibrite Lumibrite is a luminous paint that is completely harmless to human beings and the natural environment; containing no noxious materials such as radioactive substance. Lumibrite is a newly-developed luminous paint that absorbs light energy of the sunlight and lighting apparatus in a short time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the watch is exposed to light and the distance from the light source to the watch. ※ In general, when you enter a dark place from a bright environment, your eye cannot adapt to the change in light levels quickly. At first, you can hardly see anything, but as time passes, your vision gradually improves.

(The chronograph hands do not move.) The mainspring has not been wound. Turn the crown to wind the mainspring and reset the time. While you are wearing the watch or when you take it off, check the remaining power shown by the power reserve indicator and wind the mainspring if necessary. The watch stops even though the power reserve indicator is not showing "0." The watch has been left at a low temperature (below 0ºC). Turn the crown to wind the mainspring and reset the time. At a temperature below 0ºC, the watch may stop if the power reserve indicator is showing less than one-sixth of the power reserve. The watch has been left or worn in extremely high or low temperatures. Return the watch to a normal temperature so that it works accurately as usual, and then reset the time. The watch has been adjusted so that it works accurately when it is worn on your wrist under a normal temperature range between 5ºC and 35ºC. The watch temporarily gains/loses time. The watch has been left close to an object with a strong magnetic field. Correct this condition by moving and keeping the watch away from the magnetic source, and reset the time. If this action does not correct the condition, contact the retailer from whom the watch was purchased. You drop the watch, hit it against a hard surface, or wear it while playing active sports. The watch is exposed to strong vibrations. Reset the time. If the watch does not return to its normal accuracy after resetting the time, contact the retailer from whom the watch was purchased. The date changes during daytime. The time is set 12 hours ahead or behind the correct time. When you set the time, note that the moment the date changes is midnight. When setting the hour hand, be sure that AM/PM is correctly set. Even though you wear the watch every day, the power reserve indicator does not move up. The watch is worn on your wrist only for a short period of time, or the amount of arm movement is small. Wear the watch for an extended period of time. Or turn the crown to wind the mainspring. Right after starting the watch, it seems that the second hand moves more quickly than usual when setting the time. When the watch starts moving, it takes a little time before the speedregulating unit starts operating. (This is not a malfunction.) It takes several seconds before the speed-regulating unit starts operating. To set the time correctly, wait for approximately 30 seconds after the second hand starts to move, and set the time. Blur in the display persists. Small amount of water has got inside the watch due to deterioration of the gasket, etc. Consult the retailer from whom the watch was purchased. ※ For the solution of troubles other than above, contact the retailer from whom the watch was purchased. 41
