A watch with ANTIMAG. I indicated on it is a type 1 antimagnetic watch that maintains performance when moved close (about 5 cm) to a device that generates a magnetic field.
Water resistance| The water resistance performance is indicated on the case back.
A watch with WATER RESISTANT indicated on it has enhanced water resistance performance.

To Maintain Stable Operation

Be sure to expose the dial to light (recharge the watch) on a regular basis. This product is powered by solar charging.

TIP

Leaving the watch for a long time in a dark place where it is not charging may result in a low energy level.
⇒ 『Charging Method』
The energy level is low if the second hand does not move in continuous 1-second intervals. Adequately charge the watch.
⇒ 『Energy Depletion Warning Function』

Charging Method

The watch charges when light hits the dial.
To operate the watch when it is stopped or if the battery level is low, charge the watch in accordance with the estimated required charging time.
○when you start using the watch:
There may be insufficient energy. It does not have to be fully charged but make sure that it is adequately charged.
○If the second hand moves in 2-second intervals:
Charging is insufficient. Charge the battery until the second hand moves continuously in 1-second intervals.
⇒ 『Energy Depletion Warning Function』

TIP
Two-second interval movement indicates movement of the second hand in 2-second (2-unit) intervals.

Caution

Do not place the watch near light sources that generate heat while charging (such as lights for photography or incandescent lights).
The watch may overheat causing a fire, failure, or malfunction to occur.
Do not charge near a light source with high illuminance (LED, etc.).The watch and band may causing cause discoloration.

Estimated Required Charging Time

IIlumina nce (lx)	Light source	Environment	Required charging time
Full charge	Continuous 1-second interval
movement	One day’s operation
700	Fluorescent light	General office
3,000	Fluorescent light	30 W • 20 cm	Approx. 65 hours

※１:
Charging for longer than the required time for full charge will not damage the watch.The overcharging prevention function operates automatically.

※２:
This is the time required to charge the watch from 2-second interval movement to continuous 1-second interval movement when a stopped watch is exposed to light. If the charging time is too short, the second hand starts moving in 1-second intervals but may immediately revert to 2-second interval movements. Charge in accordance with the estimated required charging time.
＊The figures in the table are for reference only.
The actual required charging time may differ depending on the model.

Energy Depletion Warning Function

The second hand moves in 2-second intervals when the energy level is low.

When the second hand moves like this, the watch is likely to stop within about one week. Adequately charge in accordance with the estimated required charging time.
See hear ⇒『Reference Position Adjustment of Stopwatch Hands』

How to Set the Time

Pull out the crown to the 2nd click position when the second hand reaches the 60 seconds position.
Turn the crown to set the current time.

TIP

The 24-hour hand is synchronized with the hour hand.
When setting the time on a watch with a calendar, take care not to mistake a.m. and p.m. Turn the crown in the direction that the hands move. It is “a.m.” when the date switches.
To set the time accurately, advance the minute hand by about 4 or 5 minutes and then return it to the current time.

Push the crown in to the normal (0 click) position while listening to time signal.

How to Set the Calendar

Caution
Do not set the calendar while the hands are in the time range below.
9:00 p.m. to 1:00 a.m.
The calendar will switch in this time range.
If the calendar is set in this condition, the calendar may not switch the next day.If you want to set the calendar, move the hands out of this time range.

Pull out the crown to the 1st click position.
＊ The position of the calendar may differ depending on the model.
TIP
The crown of this watch can be pulled out to two click positions.
Turn the crown clockwise to set the date.
Push the crown in to the normal (0 click) position.

Date correction at end of month
The date must be corrected for short months.
Set the date to the “1st” when the date becomes the 1st of the next month.
(A short month is a month with fewer than 31 days.)

Troubleshooting

Symptom	Possible	Remedy and reference

・Second hand has stopped
・Second hand moves in 2-second| Energy level is low| Charge the battery ⇒ 『Charging Method』
Second hand does not move continuously in 1-second intervals after charging| ・Incident light is too weak
・Charging time is too short| ・Charge in accordance with the estimated required charging time ⇒ 『Estimated Required
Charging Time』・If the problem persists,

＊ If resetting the system does not solve the problem, the watch may be defective. Contact the customer service center (TEL: 042-847-3380).
