You have to unscrew the knob first then you will be able to pull it out to change the minutes, hours, date. You may have to use a pair of small pliers to initially turn the knob.

I couldn't find the instructions for your watch but as watches tend to have similar operating characteristics, try this:-

Press the mode button until you come to a message that says something like "12hr" or "24hr" or something that indicates display change.

Then press one of the two buttons on the right to change to the display you require.

Some experimenting may be required!

Good luck!
