You may have the watch configured for Auto Receive of the time calibration signal, 

which will cause the time to be adjusted automatically according to your currently 

selected Home City. If this results in the wrong time setting, check your Home City 

setting and correct it, if necessary.

Signal reception on a day for switching 

between STD (standard time)/DST 

(daylight saving/summer time) may have 

failed for some reason.

Perform the operation under “To get ready 

for a receive operation”. The time setting will 

be adjusted automatically as soon as signal 

reception is successful.
If you are unable to receive the time calibration 

signal, change the STD (standard time)/DST 

(daylight saving/summer time) setting manually.
