Setting the Time and Date on Your G Shock Watch

To accurately program your G Shock watch, the first critical step is setting the correct time and date. Most G Shock models follow a similar procedure, though slight variations may exist depending on the specific model. Begin by entering the time setting mode, which typically involves pressing and holding the “Adjust” button for a few seconds until the watch beeps or the display flashes.

Once in time setting mode, you can cycle through different adjustable parameters such as seconds, hours, minutes, year, month, and day. Use the “Mode” button to toggle between these parameters. Adjust each value using the “Forward” or “Reverse” buttons, often labeled as “Light” or “Start/Stop” depending on the model.

Pay special attention to the 12-hour or 24-hour format setting. Some models allow you to toggle between AM/PM and 24-hour military time, which can be done by advancing the hour past 12 or through a dedicated setting.

Here are key points to remember during time and date programming:

  • Ensure the watch is in standard timekeeping mode before starting.
  • Hold the “Adjust” button until the display flashes to enter setting mode.
  • Use the “Mode” button to navigate through seconds, hour, minutes, year, month, and day.
  • Use “Forward” and “Reverse” buttons to adjust each setting.
  • Confirm and exit by pressing the “Adjust” button again.

Programming Alarms on a G Shock Watch

Most G Shock watches feature multiple alarms, which can be programmed individually. To set an alarm, enter the alarm mode by pressing the “Mode” button until you reach the alarm display, typically indicated by “AL” or a bell icon.

Once in alarm mode, select the desired alarm number if multiple alarms are available. Press and hold the “Adjust” button to enter the alarm setting mode. The hour digits will start flashing, signaling that you can adjust this parameter.

Use the “Forward” or “Reverse” buttons to change the hour. Press “Mode” to move to the minutes and adjust accordingly. After setting the desired alarm time, press the “Adjust” button to save and exit.

Additional alarm features include:

  • Daily alarms: Repeat every day at the set time.
  • Hourly time signal: Optional beep every hour on the hour.
  • Snooze alarm: Available on some models, allowing repeated alarms at intervals.

Using the Stopwatch and Timer Functions

G Shock watches are equipped with stopwatch and countdown timer features, ideal for timing events and activities. Access these functions by cycling through the modes using the “Mode” button.

Stopwatch:

  • Enter stopwatch mode, often labeled “STW.”
  • Press the “Start/Stop” button to begin timing.
  • Press the same button again to pause.
  • Use the “Split/Reset” button to record lap times or reset the stopwatch.

Countdown Timer:

  • Enter timer mode, labeled as “TMR.”
  • Hold the “Adjust” button to set the timer duration.
  • Use the “Forward” and “Reverse” buttons to adjust minutes and seconds.
  • Press the “Adjust” button to save.
  • Start and stop the timer with the “Start/Stop” button.

Configuring World Time and Other Advanced Features

Many G Shock watches offer world time functionality, enabling the user to view the current time in various cities worldwide. To program world time:

  • Enter world time mode via the “Mode” button.
  • Use the “Forward” and “Reverse” buttons to scroll through city codes.
  • Some models allow customization of the city codes or the addition of daylight saving time (DST).

Other advanced features you may encounter include:

  • Auto LED light: Automatically illuminates the display based on wrist tilt.
  • Power saving mode: Reduces battery consumption by turning off the display during inactivity.
  • Radio signal reception: Synchronizes time via atomic clock signals.

Below is a summary of common button functions across popular G Shock models:

Button Common Label Primary Function
Top Left Adjust Enter/Exit setting mode
Bottom Left Mode Cycle through modes (Time, Alarm, Stopwatch, Timer, World Time)
Top Right Light / Start Illuminate display / Start stopwatch or timer
Bottom Right Reset / Reverse Stop stopwatch / Adjust values backward

Setting the Time and Date on a G-Shock Watch

Programming the time and date on a G-Shock watch involves accessing the watch’s setting mode and making adjustments through the buttons on the case. Most G-Shock models share a similar interface, though some variations exist depending on the model series.
