How to put the time forward a hour - Casio G-Shock G 520D 4AVDR Cockpit Series watch

just put the hour hand forward or back 1 hour

I just got a M.Z. Berger AW206 366 so the setup should be identical.
The watch has four buttons total. I'll name then by their positions. Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR).
(BL) is your mode switch. Press it once at a time to toggle between modes, (Time, Chronograph, and Alarm). From the Time mode press (BL) three times. This will put you back in time mode with the seconds flashing. Press (TR) to toggle seconds back to '00'. Press (BR) to toggle to the next setting point, and (TR) to advance it. Just keep pressing (BR) until all the settings points are the way you want them. Note: In time setting mode it only advances the setting forward when you press (TR). So when using it to change hours display for 12/24 hour display or daylight savings time you just have to keep advancing the hour until it shows up correct. There is no DST or 12/24 display toggle on this watch. You just have to change the hours display manually. To exit time setting just press (BL) once.

Simply advance hands 12 hours forwards (clockwise). Just pull out crown to the time setting position and turn the watch hands forwards if the date is changing before midnight. If the date is changing after midnight - turn the hands 12 hours backwards. Don't do this when the actual time is between 10pm - 2am.

i need to set home time

The date may be off by 12 hours.  This would cause it to change at noon, and not change at midnight.
 Try forwarding the time or reversing the time 12 hours in the correct direction.

I just dug my watch out after not wearing for a few years and had the same problem. There is an easy way to adust this watch's time and alarm, basically one way to enter both.

1) With the watch in the regular time display mode (doesn't matter if 12 hour or military time), depress and hold the lower left hand button (mode button). After a few seconds the watch appears to shift to alarm mode and it is blinking. This puts you into the mode for adjusting the alarm.

2) If you want to adjust time, date, etc rather than alarm time, after you have done step one, simply press that same lower left button again, and then it will put you into the time mode, but this time the time mode is blinking and you can adjust the various components (seconds, minutes, hours). You can only move minutes, hours, etc forward, no way to move backward. You will start off with the second display blinking, probably skip that unless you need to adjust seconds. Depress the upper right button to shift to the next option (minutes) and you will see the minute display blinking. Adjust the minutes by depressing the lower right button. When finished depress upper right button to move to next option (hours) depress the lower right button to move the minutes/hours/month/date forward as necessary, when you finish just press the lower left button again and it pulls you out of adjust mode and you are back in regular time viewing.

I had to post this because I've had this problem in the past and it killed me. Its kind of intuititve after you get into the adjusting mode by pressing the lower left button- remember, initially it will put you into adjust alarm mode, but press again and you will get into adjust time mode.
