Setting the World Time Mode

To adjust the World Time feature on your Casio World Time watch, begin by entering the World Time mode. This mode allows you to view the current time in various cities around the globe, making it especially useful for travelers or those working with international contacts.

Press the mode button repeatedly until the World Time screen appears, usually indicated by a city code and the current time in that city. The city code represents the time zone you are currently viewing.

To change the city code and view the time in a different location, use the following steps:

• Press the forward or reverse buttons (often labeled as D or B) to scroll through the available city codes.
• Each press will advance or reverse the city code by one time zone.
• Hold down the button to scroll rapidly through the list.
• When the desired city code appears, release the button to stop.

The watch will automatically update the displayed time based on the selected city code, including adjustments for daylight saving time if applicable.

Adjusting Daylight Saving Time (DST) Settings

Many Casio World Time watches allow you to manually toggle Daylight Saving Time on or off for the selected World Time city. This feature ensures the displayed time matches local time accurately during DST periods.

To adjust the DST setting:

• While in World Time mode, hold down the adjust button (usually the top-left button) until the city code starts to flash.
• Press the forward button to toggle DST on or off. The watch may display an indicator such as “DST” or a small icon when DST is enabled.
• Press the adjust button again to confirm and exit the setting.

It is important to verify whether the city you have selected observes DST, as incorrect settings can result in a one-hour error.

Setting the Home City Time

The Home City time is the primary time zone that your watch displays in the Timekeeping mode. Setting this correctly ensures that alarms, timers, and other functions operate based on your local time.

To set the Home City:

• Enter the Timekeeping mode by pressing the mode button until the standard time screen appears.
• Hold the adjust button until the city code starts to flash.
• Use the forward and reverse buttons to select your home city code from the list.
• Confirm the selection by pressing the adjust button again.

After setting the Home City, the watch will synchronize all functions to that time zone, including automatic adjustments for DST if enabled.

Understanding City Codes and Time Zones

Casio World Time watches use standardized three-letter city codes to represent time zones. These codes correspond to major cities within each time zone, making it easier to identify the correct setting.

City Code	Time Zone	UTC Offset	Example City
NYC	Eastern Time	UTC -5	New York City
LON	Greenwich Mean Time	UTC +0	London
TYO	Japan Standard Time	UTC +9	Tokyo
SYD	Australian Eastern Time	UTC +10	Sydney
DXB	Gulf Standard Time	UTC +4	Dubai

Choosing the correct city code ensures accurate time display. Some watches allow for additional city codes representing other regions, so consult your model’s manual if you do not find your city listed.

Synchronizing Time with Radio Signals

Certain Casio World Time models feature Multi-Band 6 or similar radio-controlled synchronization, which automatically adjusts your watch’s time and date based on atomic clock signals.

To enable or check synchronization:

• Make sure the watch is in Timekeeping mode.
• Hold down the adjust button until the seconds digits flash.
• Press the mode button to access the signal reception setting.
• Use the forward button to toggle between manual and automatic reception modes.
• Place the watch near a window during the night for optimal signal reception.

The watch will attempt to receive time calibration signals at preset times. Successful synchronization ensures the highest accuracy without manual adjustments.

Using Additional Features Related to World Time

Your Casio World Time watch may include features that complement the World Time function:

• Alarm Settings: Alarms can be set based on either the Home City or World Time zone.
• Stopwatch and Timer: These functions typically operate independently but are influenced by the Home City time setting.
• Calendar Display: Automatically adjusts based on the time zone and DST settings.

Understanding how these features interact with your World Time settings can maximize the watch’s utility for daily use and travel planning.
