Features This watch is a solar-powered watch equipped with a solar cell in the watch dial that converts light energy into electrical energy to power the watch. [. . . ] Correct the date by turning the crown to the to the left to set to the first day of the following month in months with less than 31 days (months with 30 days and February). · Avoid correcting the month when the date hand indicates a date from the 31st to the 2nd. If you want to correct the month during this time, wait until the date hand is outside the range of the 31st to the 2nd. · When turning the crown to the left (counter-clockwise) when correcting the time or day, the changing of the date may change a day late during normal use. 14 15 5. Unique Features of Solar-Powered Watches When the watch becomes insufficiently charged, the watch display changes as shown below. [Normal Time Display] [Insufficient Charge Warning Display] [Watch Stopped] If insufficiently charged If the capacity of the secondary battery becomes low without charging When charged 2 seconds 2 seconds The time is incorrect since the watch has stopped as a result of being insufficiently charged. Reset the watch to the correct time. The second hand changes to 2-second interval movement Sufficiently charge the watch by exposing to light until the watch hands begin to move. 16 17 <Insufficient Charge Warning Feature> When the watch becomes insufficiently charged, the second hand begins 2-second interval movement to indicate that the watch is insufficiently charged. 2 seconds · Although the watch continues to run normally at this 2 seconds time, the watch will stop after about 4 days have passed since the watch has become insufficiently charged. Charge the watch by exposing to light to return to the original 1-second interval movement. Sufficiently charge the watch even after it has returned to 1-second interval movement to ensure that it can be used comfortably. There is no risk of overcharging since the watch is provided with an overcharging prevention feature. · Although the watch will begin to run again when exposed to light after it has stopped due to being insufficiently charged, since the time is incorrect, reset the time after sufficiently charging the watch. <Overcharging Prevention Feature> When the secondary battery becomes fully charged as a result of exposing the watch dial (solar cell) to light, the overcharging prevention feature is activated automatically to prevent the battery from being charged further. Consequently, there is no degradation in the performance of the solar cell or secondary battery no matter how often the watch is charged. This lets you expose the watch to light without worrying about overcharging. <Quick Start Feature> The watch will stop running if it is not charged at all. The watch hands will begin to move after about 10 seconds when the watch is exposed to light. (The time until the hands begin to move varies depending on the model of the watch and the intensity of the light. ) However, please note that the watch may stop again since it will not be adequately charged if the light is blocked at this time. 18 19 6. General Reference for Charging Times The time required for charging varies according to the model of the watch (color of the dial, etc. ). * Charging time refers to the amount of time the watch is continuously exposed to light. Charging time Illuminance (lux) Environment Approx. charging time for 1 day of operation 4 hours 2 hours 40 minutes 11 minutes 3 minutes Approx. charging time from the stopped state until 1-second interval movement Approx. charging time from the stopped state until fully charged [Note] · Once fully charged, the watch will continue to run for about 6 months with any additional charging. As shown in the table above, a considerable amount of time is required until the watch starts running once the watch has stopped as a result of being insufficiently charged. Try to keep your watch sufficiently charged at all times by charging everyday. [. . . ] · Do NOT subject the watch to a strong shock such as dropping it onto a hard floor. · Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.
