I don't know how much significance this post would make to any now, but I was playing with the watch trying to figure out how to set the time and I have figured it out...

1. Hold the "Adjust" button until where it displays the day of the week starts blinking (This will display the major airport in your area to determine your time zone, mine is "LAX" change this, while it is still blinging press either "Time Memo" or "Recieve" to move up or down)

2. Press "Adjust" again so you see "12H" (I guess meaning 12 hour intervals)

3. Press "Mode" (at this point your seconds will start blinking) to change these, againg press "Time Memo" or "Recieve" to move up or down. (usually I skip past the seconds)

4. Repeat step 3 to do your hours, minutes, year, then the date...(order is as follows)

5. When you are done press "Adjust" then everything will stop blinking, and you are done

This is as much as I figured out and I hope this is helpful to anyone that needs it...

The backlight comes on with wrist movement because you have it set to do that. hold the back light button until you hear a "beep" and it'll change the setting

I cant set the date, because I got the battery replaced and I the date is two days late

Use the manual to set the correct time zone, time and date. Manual is available on the Casio worldwide website>support>manual>watches.
Have the module number at hand: you will enter it to find the manual. The module number is a 3 digit or 4 digit number on the back of the watch.

Reset the time on a G shock GW 1500A

The least time-consuming method is to follow the instructions in the manual. Download the manual for the watch module from Casio worldwide site. The module number is a 4-digit number set inside a rectangle on the back of the watch. Usually on the periphery of the circle.

Hi i have a g-shock gw-2000b watch and its running 12 hrs ahead and i can't figure out how to get it right

I'm not familiar with this watch but it sounds as though it thinks it is some other part of the planet.

If this is so, then you need to reset the location setting.

If you haven't got instructions on how to do this, you can get
instructions from the Casio web site.

Go to the casio web site "".

Select "support" and the "manuals",

Accept terms

Select "watch manual archive"

Read the number of the back of your watch and enter it into the search box

Casio G-Shock GW-300 replacement bands

I have a Casio g-shock gw-330a and now find myself again replacing the band. So far, $60 on bands. They last me two or three years. To install the band, take the band and watch to a Jeweler. My local Sears does it for me. $5 for installation; $5 for purchase shipping; $20 for band. $30 every couple of years.
This cost disturbs me.

I need to set the time on my g-shock 330a watch

Hi, mate. Do not know how it's going in Afghanistan right now, but I hated every single bit in that country 28 years ago (Russian invasion).
Unfortunately I was in service in Soviet Army, so, we would be shooting each other if you were there at that time.
Right now I'm very happy, 'coz I was fortunate enough to escape from Soviet Union 20 years ago and find my refuge in England.
Anyway - deepest respect to the guys servicing their own homeland in such a hot spots.
OK, back to business:
