On my Casio G-shock GW500A, the time is off. i dont want it on 24time and its an hour ahead

Unfortunately I can not check out watch functionality by model number GW500A-1V. Follow this link and enter required number.Casio online manuals sometimes differ from those supplied with watches, so, download this one and follow instructions. See if it'll help. http://world.casio.com/wat/download/en/manual/

Nothing you can do. Where you work (middle east) there is no time signal radio station for your (radio controlled) wave ceptor watch.
You can read more here:

Press the "adjust button" until display flashes.By pressing "mode" button
go to 12/24h setting.Press the lower left button to switch between 12/24h.
When finished press the "adjust"button again.

Which do you have a g-511 or a g-shock gw500A-1V which iswhat you are posted under?
The GW500A-1V is an auto set model that will set itself back to EST at 2:00AM
However, if you want to do it manually its pretty much the same procedure forboth watches
First press the mode button (the Lower left one) until the hour and AM/PMindicator are flashing
Then press the set/reset button (lower right) to cycle through til its one hourearlier than when you started
When the time is where you want it, press the mode button again.
Hope this helps, if not re-post with more details about specific model andfunction you are trying to access.
