From memory you either press the A + C buttons at the same time or it will give you the option to turn it off during the time setting function. Most Casio instructions are available online through Casio

1. Press [A], the top left button, and the seconds should start flashing 2. Once you have some digits flashing, press [D], bottom middle button, and will switch between the 12h/24h formats 3. Wait a few seconds and the digits should stop flashing and return from the time set mode, to timekeeping mode.
Here is a link to a manual directly from Casio, showing you all of these steps. As per the explanation on top of the manual, this should work with 3 different models of Casio watches, including yours. http://ftp.casio.co.jp/pub/world_manual/wat/en/qw1659.pdf
