5. After the setting is the way you want, press
A
to return to the Timekeeping Mode.
• The DST indicator appears to indicate that Daylight Saving Time is turned on.
• Exiting a setting mode will normally cause the hands to return to regular
timekeeping automatically. However, if you manually move the hands (page E-60)
and then enter a setting mode, they will not return to regular timekeeping
automatically when you exit the setting mode. In this case, you will need to return
the hands to their normal positions manually (page E-61).
Note
• After you specify a city code, the watch will use UTC* offsets in the World Time
Mode to calculate the current time for other time zones based on the current time in
your Home City.
* Coordinated Universal Time, the world-wide scientific standard of timekeeping.
The reference point for UTC is Greenwich, England.
