There are several models of your watch not all of which appear to have a 12/24 hour display format.

Try this extract from a manual; press the MODE button six times to enter the 12/24 adjusting setting and then use the START/STOP or SPLIT/RESET button to change the time.

Press the mode button to return to normal operation.

This is the same as military time. If there is a "NEXT" button on the upper-right side of the watch, use this to advance to the 24-hour option instead of using the "SPLIT/RESET" button. You may need to press a "START/SPLIT" button instead a "SPLIT/RESET" button to cycle between 12- and 24-hour display. The "START/SPLIT" button could be located below the watch face or on the upper-right side of the watch, depending on the model.<br /></li> <li id="ecxjsArticleStep5"> Press the "SET" button again. You are now done.

To change between 12 & 24 hour display, press the mode button (bottom left) and then the bottom right button to change format. Press mode until normal display is achieved.

The instructions are not very clear but sa far as I can make out you hold button 3 (the one at the 4 O'clock position) for two seconds and the time should change to 12 hour display.
