My g-shock ga-110c-1a hour hand is 6 hours ahead. The digital time is correct but the hour hand is six hours ahead. If i set the time at 6:00pm the hour hand will move to 12:00. the minute hand is fine, i just got it about four days ago. It was working at first but when i changed the city the hour hand move an extra 6 hours. i tried every other city and it will stay 6 hours ahead. I tried turning it manually but every time i press the adjust button it goes back to its location

make sure the dial is pressed all the way in

Hand home positioning normally has nothing to do with time setting.
Just set your local time and date and then you can do the hand home positioning procedure.This will not affect the time setting.If hands,after a while,do not show correctly,this means that the watch is under severe magnetic field, after severe shock or finally watch malfunction.
You must know that on this type of watches analog time follows digital time.

Analog time follows digital time.Correctly set your local time and analog time will come up correctly as well.If not, try to run the hands alignment procedure (H-SET) following manual instructions.

Check MUTE ON-OFF setting.

Go to "setup" pushing mode sometimes then right down push should move analog clock

Here is how to set the Invicta 6106 Invicta 6107 and other similar models with the ISASWISS 8173 movement with the following functions:
TIME - DATE - DAY - ALARM - GMT - POWER RESERVE

DO THINGS IN THIS ORDER AND YOU WILL FIND IT TO BE VERY EASY! After you understand how to set ALL the functions you can skip steps later to set individual functions but for now just do it exactly step by step:
1. Unscrew the center crown (if it is a screw down crown) and pull it all the way out (this is position 2) and turn it until you see the DAY sub-dial at the 6:00 position set to the day BEFORE today. There is no QUICK SET for the day on this movement so you must just keep turning the crown and hour hand past 12 midnight and watch the day pointer until it gets to the day you want - the day BEFORE today.
2. Now set the time to 6:00 (am or pm doesn't matter at this point). This is very important because you do not want the time to be between 9:00pm and 12:00pm when you set the date later on - we are using 6:00 just to be safe.
3. Push the crown all the way in - you don't have to screw it down.
4. Now pull out the crown very gently to the 1st position - just one "click" out. Now turn the crown AWAY from you to set the date to the date BEFORE today - this appears in the small window at the 4:00 position.
5. Now pull the crown all the way out again to position 2 and turn it away from you until it goes past 12 midnight and TODAY's DAY AND DATE are showing and then adjust the hour and minute hands to the current time - be sure to set the hour to AM or PM and push the crown all the way in. If you wish to set the seconds exactly - with the crown pushed in watch until the small seconds hand in the sub-dial at 2:00 is exactly at 60 and then pull the crown out to Position 2. Set the time ahead a minute or so and push the crown in when the actual time is the time you have set - you can set it to atomic clock time on the internet or by another watch that sets itself to atomic time.
6. Now the DAY, DATE and TIME are set to current. Now when the hour hand passes 12 at midnight tonight the DAY and DATE will advance correctly.

YOU CAN STOP HERE IF YOU WISH - but you can continue on to set the ALARM and the GMT indicators as follows:

7. To set the GMT hand (the one with the red-bordered pointer) the crown is pushed all the way in and screwed down. Now simply hold the bottom pusher in for a few seconds until you hear a beep - now you can start pushing it and watch the GMT hand moving - one push at a time for small adjustment or hold it down to make it move faster. When you stop pushing it another beep indicates that it is OUT of the setting mode - so if you want to adjust it again just hold it in until short beep and start pushing the lower pusher same as above.

Understanding GMT (or second time zone): Note that the GMT hand time is indicated on the 24 hour dial (think in military time where 3:00AM is 0300 and 3:00PM is 1500) using the very small numbers around the very outside of the dial. When the local time is 3:00PM if GMT is adjusted for the SAME TIME ZONE as you are in now the GMT HAND will be pointing at the small "15" which is between the 7:00 and 8:00 hour markers. If the local time is 3:00AM and the GMT is adjusted for the SAME TIME ZONE as you are in now the GMT HAND will be pointing at the small "3" between the 1:00 and 2:00 hour markers. So lets say you are in Pacific Time Zone and it is now 3:00pm local time and showing on the minute and hour hands - and for example you want the GMT hand to show Eastern (New York) time which is 6:00pm (in military time that is 1800 indicated by the very small 18 which aligns with 9:00) - hold in the bottom pusher until you hear a beep - now start pushing it in short increments or hold it down to move it faster until it points to small 18 (large 9). Now the GMT will indicate the hour in the EASTERN time zone while the main hour hand indicates your local time.
7. To set the ALARM - unscrew the crown and pull it to Position 1. Turn it TOWARDS you (if you turn it way from you will set the date which you don't want to do) and you will see the hand with the white pointer and the word "Alarm" in tiny writing on it move clockwise. Set the ALARM to the time you want. Push in the crown and screw it down.
8. To activate the ALARM push the TOP PUSHER once - the small hand in the POWER RESERVE sub-dial will move slightly and then it will move again (give it a second or so) and you will hear a BEEP - now the alarm is activated and the small hand points to the "ON" label. When the alarm sounds if you wish to stop it push the top pusher. But it will stop on its own and then repeat a few minutes later - you can just leave it alone if you wish. Note that the Alarm will turn OFF after sounding - so if you want to wake up for work on time tomorrow be sure the ALARM indicator is pointing to "ON".
9. To deactivate the ALARM when the small hand is pointing towards the "ON" label simply push the top pusher again and and the small hand will move clockwise down to the "OFF" label.
10. POWER RESERVE sub-dial. To align the Power Reserve sub-dial hand (after battery change) pull the crown out to Position 1 and push the top pusher until the hand points to 0%. Push the crown back in and screw it down.
11. Reserve Indicator - the instructions for this movement states that holding down the top pusher for 3 seconds will move the POWER RESERVE hand to the power reserve scale - but this is confusing because the hand never actually stays on the power reserve scale - it will only stay on "ON" or on "OFF".
However - I believe that this is the way it works. When you push the top pusher with the small hand in the "OFF" position it will momentarily move to the power reserve scale and stop for a second before it moves again to "ON" - I believe that this reading indicates the POWER RESERVE just before it moves again to the "ON" position..

It sounds like your watch is set to the wrong time zone. If you haven't got instructions, you can get them from their web site.

You need to manually adjust or set the hands to the home position as they are not where the watch thinks they should be. This can happen when you bring your watch close to a strong magnetic field. Look in the manual to do this. Afterwards your watch should set to the correct time.

The hands are set independent from the digital display
