[This is basically just a convenience post as I can never remember how to do this.]
I have a Casio G-Shock watch (GW-2000) with the 5060 module. This watch can be synced by radio time signal, but unfortunately it doesn’t work where I live. So I have to reset the time manually now and then, as the watch gains about 15 seconds/month.
- Keep Ⓐ depressed for about 5 seconds. The Second Hand will got through Last Signal Reception (Y or N), to READY and then finally to the city code for the selected Home City.
- At the same time, the [4] Left Dial Hand will indicate the currect DST setting for the Home City (STD or DST).
- If you wish to switch DST settings, press Ⓑ to switch them.
- To set the time, press Ⓒ to enter time setting mode. The Second Hand and the Left Dial Hand will move to their 12 o’clock positions.
- Press Ⓓ (+) or Ⓑ (-) to move the Minute and Hour hand to the correct time.
- Press Ⓐ to return to timekeeping mode.
Setting the Home City
- Keep Ⓐ depressed for about 5 seconds. The Second Hand will got through Last Signal Reception (Y or N), to READY and then finally to the city code for the selected Home City.
- Change the Home City by pressing Ⓓ to move the Second Hand to the desired Home City. The Hour and Minute hands will move too, wait until these have stopped moving before proceeding.
- Press Ⓑ to toggle DST in the selected city.
Switching time display between Home City and World Time City
- Use Ⓒ to move the Left Dial Hand to SDT or DST. You are now in World Time City mode. You can now use Ⓓ to set the World Time City - the seconds hand will point to it.
- Hold down Ⓑ for about 3 seconds to switch the main time display from the current Home City to World Time City. The Right Dial will now show the time in the Home City.
