3.Hold down Afor about two seconds to toggle between daylight saving time and standard time.

ξChanging the setting will cause the x Second Hand to move to STD or DST.

ξThe x Second Hand will return to the city code you selected in step 2 after about ﬁve seconds, or if you press Aagain.

ξIf you want to conﬁgure other settings, wait until the x Second Hand moves back to the city code before proceeding.

ξYou can select STD or DST for each World Time City code, except UTC.

ξAs you hold down B, the x Second Hand will move to either AM (A) or PM (P), and then the watch will enter the regular timekeeping mode.

current time in your Home City.

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

ξSelecting some city codes makes it possible for the watch to receive the time calibration signal for the corresponding area automatically. See page E-11 for details.
