ξNote that you cannot switch between STD (standard time) and DST (daylight saving time) while UTC* is selected as your Home City.

*Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for UTC is Greenwich, England.

ξIf you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually (page E-53).

STD/DST Switching

STD/DST switching can be performed either automatically or manually, depending on time calibration signal reception conditions in your area, the use of daylight saving time in your area, etc.

−To configure the watch to switch between STD and DST automatically in accordance with a time calibration signal, see “To toggle the Home City time between standard time and daylight saving time” (page E-51).

−To override time calibration data and use a fixed STD/DST setting, see “To manually override a time calibration standard time/daylight saving time setting” (page E-53).
