G-SHOCK watches are trusted worldwide for their high durability and accurate time display. However, since the method for setting the time varies depending on the model, it is important to know the correct operation method. In this article, we will explain the features and specific operation methods of each model, from basic manual settings to the latest smartphone connectivity features.
Basic time setting method for G-SHOCK
On a digital G-SHOCK, the time is set using just a few buttons. Even if you're using it for the first time, once you understand the procedure, you can easily set the time. This section explains the basic time setting method common to many G-SHOCK models.
The names of the buttons on a G-SHOCK vary depending on the model. The main buttons used to set the time are as follows:
- Buttons for switching to time setting mode: ADJUST button, adjustment button, SET button, etc.
- Buttons for switching setting items: MODE button, mode button, etc.
- Buttons to adjust values: RESET button, START button
To set the time, first press and hold the ADJUST button, then press the MODE button. From here, each time you press the setting item switch button, the available settings will change. The available settings vary depending on the model, but in most cases they are in the order of seconds, minutes, hours, day, month, and year. To change the values for each item, use the buttons to adjust the values. Once all settings are complete, press the button to switch to time setting mode again to return to the normal time display. This series of operations allows you to set the time accurately.
To set the time accurately, it is essential to adjust it down to the second. Here are the techniques for doing so:
- Check the current time (on your smartphone, for example) and set the G-SHOCK to the same time.
- Press the button to switch between settings, causing the seconds display to flash.
- Wait for the moment when the next minute changes (e.g. 19:21:00) and press the button to adjust the value at that point.
The above operation allows you to set the time accurately down to the second, which is particularly useful when you want to measure time accurately or when you want to synchronize multiple clocks.
Please note that the operation varies depending on the model (module), so this method cannot be applied in general. Please check the instruction manual for each model below.
How to set the time on a radio-controlled clock
G-SHOCK radio-controlled watches automatically maintain accurate time by receiving standard radio waves. In this section, we will explain the features of analog and digital radio-controlled watches and how to adjust them.
Analog radio wave model adjustment
For analog radio-controlled clocks, it is important to "align the reference position" so that the hands of the clock point to the correct position. Adjustment is performed using the following procedure.
Checking the reference position
Check the "Setting the Hands/Date Reference Position" section in the instruction manual and make sure that the hour hand, minute hand, and depending on the model, the second hand are in the correct reference positions. If they are not in the correct reference positions, manually correct them as necessary.
Setting the home time and daylight saving time
Set your watch's home city to match the region you live in. Also, make sure that automatic Daylight Saving Time (DST) setting is enabled.
Executing radio wave reception
If the time is not correct, use the "Manual Receive" function. Follow the procedure and note the following points before starting reception.
- Place the clock with the glass side facing up near a window.
- Choose a suitable time for reception (usually at night).
Digital radio wave model adjustment
For digital radio-controlled clocks, you can set the time by checking the reception status on the LCD screen. Follow the steps below.
Starting manual reception
Follow the "Manual Reception" procedure in the instruction manual to begin reception. On many models, reception can be initiated by pressing and holding a specific button (e.g., the "RECEIVE" button) for several seconds.
Confirmation of receiving
The display will show "RC" or "RECEIVING." If reception is successful, the time will be adjusted automatically.
What to do if reception fails
If reception fails, the following operations are attempted.
- Move the clock to the window.
- Try receiving again in an environment where there are no objects blocking the radio waves (concrete walls, metal products, etc.).
- If you are in Japan, make sure you are within the reception range of the Fukushima station (eastern Japan) or Kyushu station (western Japan).
Generally, no time adjustment is required
Radio-controlled clocks have the ability to receive standard radio waves from Japan and automatically correct the time.
This standard time signal is based on an atomic clock with an extremely high accuracy of about 1 second in 10 years, so manual time adjustment is usually not necessary.
However, a suitable environment is required for signal reception. Signals are difficult to receive in the center of a building, underground, or near electrical appliances, so it is recommended that you move the watch near a window in such locations.
Also, radio wave reception is better at night, so if you place it near a window when you go to bed, the time will be set correctly the next morning.
