There are two Home City settings: actually selecting the Home City and selecting either standard time or daylight saving time (DST).
In the Timekeeping Mode, hold down E for at least two seconds. SET and Hold will appear on the display first, and then Hold will disappear. Release E after Hold disappears.
- The watch will exit the setting mode automatically if you do not perform any operation for about two or three minutes.
- For details about city codes, see the “City Code Table” at the back of this manual.
Use A (East) and C (West) to scroll through the available city codes.
- Keep scrolling until the city code you want to select as your Home City is displayed.
Press D to display the DST setting screen.
Use A to cycle through the DST settings in the sequence shown below.
- The Auto DST (AUTO) setting will be available only when a city code that supports time calibration signal reception (page E-15) is selected as the Home City. While Auto DST is selected the DST setting will be changed automatically in accordance with time calibration signal data.
- Note that you cannot switch between standard time and daylight saving time (DST) while UTC is selected as your Home City.
After all of the settings are the way you want, press E twice to exit the setting screen.
- Daylight Saving Time is turned on when the DST indicator is on the display.
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.
- Selecting some city codes automatically makes it possible for the watch to receive the time calibration signal for the corresponding area. See page E-15 for details.
