STD/DST Switching
You can select summer time or standard time independently for each city. The initial
default setting for all cities is AUTO.
Normally you should use the AUTO setting because it automatically switches between
summer time and standard time. You should change the setting to STD (standard
time) or DST (summer time) in the following cases.
−
When using a time of a location that is not included in the watch's list of 29 cities
−
When the preset AUTO standard time/summer time timing is incorrect for some
reason
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
Note that you cannot switch between STD (standard time) and DST (daylight
saving time) while UTC* is selected as your Home City.
