Q2‏All hands are stopped and buttons do not work.

The battery is dead. Keep the watch exposed to light until the battery recharges sufficiently.

Q3‏The hands suddenly start moving at high speed.

This is due to one of the reasons below, and does not indicate malfunction. Simply wait until normal hand movement resumes.

The watch is recovering from a power saving state.

Q4‏Hands are stopped and buttons do not work.

The watch is in the charge recovery mode. Wait until the recovery process is complete (for about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.

Q5‏The current time displayed by the watch is off by a few hours.

The city (time zone) setting is not correct. Select the correct setting.

Q6‏The current time indicated by the watch is off by one hour or 30 minutes.

The summer time setting is not correct. Select the correct setting.

Q7‏The time indicated by the hands is different from the digital time.

Strong magnetism or impact may cause the hands of the watch to go out of alignment. Correct hand position alignment.

World Time

Q1‏The time for a World Time City is not correct.

The summer time setting (standard time/summer time) is wrong.

Alarms

Q1‏The alarm does not sound.

Is the alarm setting turned on? If it isn’t, turn it on so it will sound.

Charging

Q1‏The watch does not work even though it is exposed to light.

The watch stops operating whenever the battery goes dead. Keep the watch exposed to light until it recharges sufficiently.

Q2‏[H], [M], and [L] are flashing on the display.

The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.

If an alarm, hourly time signal, illumination and/or other power-intensive functions are used within a short period of time, the charging capacity of the battery will drop and cause the watch to go into a charge recovery mode. Function availability will be temporarily limited, but functionality will return after the battery recovers.
