Check to make sure that the second hand of the watch is moving in 1-second

intervals when worn on the wrist.

If it is moving in 2-second intervals, this means that the watch is not suffi-

ciently charged.

Charge the watch by wearing the watch so that the back of the watch is in

direct contact with your wrist at all times until the second hand returns to 1-

second interval movement. This watch is provided with an overcharging pre-

vention function that eliminates any worries that the watch may be overcharged

no matter how long it is charged.

When the second hand is moving in 2-second hitch movement, this indicates

that the watch has stopped running as a result of being insufficiently charged.

When this happens, fully charge the watch and reset the time before further

use.

Please Make Sure to Fully Charge the Watch Before Use

Please Make Sure to Fully Charge the Watch Before Use 7 English English Check to make sure that the second hand of the watch is moving in 1-second intervals when worn on the wrist. If it is moving in 2-second intervals, this means that the watch is not sufficiently charged. Charge the watch by wearing the watch so that the back of the watch is in direct contact with your wrist at all times until the second hand returns to 1second interval movement.

2. For Proper Power Generation [Power Generation Mechanism] When this watch is worn on the wrist, body heat from contact with the skin will heat up the back cover of the watch. This heat will be released into the air from the surface of the watch, and the temperature difference between the back cover and the watch surface will drive a thermoelectric generation device that generates electric energy.
PAGE 4
[General Reference for Charging Times] Wear the watch on the wrist for at least 5 hours per day to ensure one day’s worth of charging at the time of 1-second interval movement. If the watch stops due to insufficient charge, full charge using the 1-second interval movement will take about 50 days provided that the watch is worn for 8 hours per day. However, make sure to attach the watch to the wrist in the correct manner, as the way the watch is attached will greatly affect the time required for charging.

3. Setting the Time and Calendar If the watch has stopped running due to insufficient charging or the second hand is moving at 2-second intervals when setting the time, first return the watch to 1second interval movement before setting the time by charging with reference to the section entitled, “For Proper Power Generation”. If the crown is a screw lock type, the screw should be loosened before the operation. Make sure to tighten the screw again after the settings are made.
PAGE 6
Caution If the crown is pulled out to the time correction position when the second hand is at another position than the 0-second, 10-second, 20-second, 30-second, 40second or 50-second position, or if the second hand does not stop at the 10second interval movement stop positions due to the influence of static electricity or physical impacts, perform the following procedure to set the correct time again. 1.

4. Characteristic Functions The display of this watch changes following the activation of the warning functions described below when the watch is insufficiently charged.
PAGE 8
5. Warning Functions The display of this watch changes when the warning functions described below are activated as a result of the watch being insufficiently charged. The watch does not change to 10-second interval movement even if power is not generated while any of these functions are activated. [Insufficient Recharging Warning Function] When the second hand is moving at 2-second intervals (moves two gradations at a time every 2 seconds), this indicates that the watch is insufficiently charged.

6. Secondary Battery WARNING Handling of the Secondary Battery current consumption and extend the duration of watch usage without charging. When using the watch after storing, make sure to first reset the time after fully charging and returning to 1-second interval movement. Never attempt to remove the secondary battery from the watch. When the secondary battery must unavoidably be removed, store in a location out of the reach of small children to prevent accidental swallowing.

CAUTION • Be sure to use the watch with the crown pressed in (normal position). If your watch has a screw-type crown, be sure to tighten the crown completely. • Do NOT operate the crown with wet fingers or when the watch is wet. Water may enter the watch and compromise water-resistance. • If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth.

• Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time. • Do NOT place the watch close to household appliances that generate static electricity.
