Each city code represents a major city within a particular time zone, allowing the watch to automatically adjust the time and daylight saving settings based on the selected location.

Once you find the correct city code or time zone, press the Adjust button again to confirm the selection. The watch will update the displayed time to match the chosen time zone, including any applicable daylight saving time adjustments.

Understanding City Codes and Their Corresponding Time Zones

Casio watches use a system of city codes to simplify selecting time zones. Each code corresponds to a major city that represents a specific time zone. This method ensures that users can easily switch between time zones without manually calculating hour offsets.

Below is a table of common city codes and their corresponding time zones frequently found on Casio watches:

City Code City Time Zone UTC Offset
NYC New York City Eastern Time (US & Canada) UTC -5 / -4 (DST)
LON London Greenwich Mean Time UTC +0 / +1 (DST)
TYO Tokyo Japan Standard Time UTC +9
SYD Sydney Australian Eastern Time UTC +10 / +11 (DST)
DXB Dubai Gulf Standard Time UTC +4

Refer to your specific Casio watch manual for a comprehensive list of city codes supported by your model, as these may vary.

Setting Daylight Saving Time (DST) on Your Casio Watch

Many Casio watches include an automatic or manual Daylight Saving Time (DST) setting. After selecting your time zone, you may need to enable or disable DST depending on your location and the current time of year.

To adjust DST:

  • While in the city code or time zone setting mode, look for an option labeled “DST” or “Summer Time.”
  • Use the Forward or Reverse buttons to toggle DST On or Off.
  • Confirm your selection by pressing the Adjust button.

Automatic DST adjustment is available on certain models equipped with radio-controlled or GPS time synchronization. For manual models, you must toggle this setting when DST begins or ends in your region.

Additional Tips for Accurate Time Zone Changes

Changing the time zone on your Casio watch can affect alarm settings, timers, and world time features. Keep these tips in mind to ensure all functions operate correctly:

  • After changing the time zone, verify that alarms and timers are still set correctly relative to the new time.
  • If your model supports world time, double-check that the world time city code remains accurate or adjust it accordingly.
  • For watches with radio signal reception or GPS synchronization, allow the watch to receive signals after changing the time zone to ensure precise timekeeping.
  • In cases where your watch displays a home city and a world time city, make sure both are correctly set to prevent confusion.

By following these steps and understanding the city code system, you can confidently change the time zone on your Casio watch to match your travel or daily routine needs.

Steps to Change the Time Zone on a Casio Watch

Changing the time zone on a Casio watch involves entering the watch’s settings mode and selecting the desired city code that corresponds to the preferred time zone. The exact procedure may vary slightly depending on the Casio model, but the general steps are consistent across most digital and analog-digital models.

Follow these detailed steps to adjust the time zone correctly:

  • Enter Timekeeping Mode: Ensure your watch is in the standard timekeeping display. This is usually the default mode where the current time is shown.
  • Access the Settings: Press and hold the Adjust button (often located at the top-left) for a few seconds until the city code or settings screen starts blinking. This indicates the watch is in the setting mode.
  • Navigate to the City Code: Use the Mode button (typically bottom-left) to cycle through different settings until the city code is highlighted or flashing.
  • Select the Desired City Code: Use the Forward or Reverse buttons (usually bottom-right and top-right) to scroll through the list of available city codes. Each city code corresponds to a time zone (e.g., NYC for New York, LON for London).

Some Casio watches automatically adjust for daylight saving time (DST) based on the selected city code. If your watch supports this feature, ensure DST settings are enabled or disabled according to your preference.

Understanding City Codes and Time Zones on Casio Watches

Casio watches use three-letter city codes to represent global time zones. These codes allow the watch to calculate the correct local time based on the selected city’s standard time and any applicable daylight saving adjustments.

City Code Location Time Zone Notes
NYC New York City, USA GMT-5 (Eastern Standard Time) Adjusts for DST
LON London, UK GMT+0 Adjusts for DST
TYO Tokyo, Japan GMT+9 No DST
SYD Sydney, Australia GMT+10 Adjusts for DST
DXB Dubai, UAE GMT+4 No DST

Refer to your Casio watch manual for the full list of city codes supported by your model. Selecting the correct city code is essential for accurate time zone adjustments and automatic daylight saving time changes.

Adjusting Daylight Saving Time (DST) Settings

Many Casio watches allow manual control over daylight saving time settings, which can be enabled or disabled independently of the time zone selection. This ensures accurate timekeeping when DST rules change or if you are in a region that does not observe DST.

To adjust DST settings, follow these steps:

  • Enter the timekeeping mode and hold down the Adjust button to access the settings mode.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
