On pages 2 and 3 of the manual (module 3043) you can find the instructions for automatic and manual time setting.

The manual can be downloaded here (direct download link):

so here is the fix if you get op en display on your casio pathfinder or whatever model. mine happens to be a paw 1200t
1. you gotta break it open 2 pins each side band comes off.
2. pry off the side pieces. this exposes 4 screws.
3. the base then comes off be careful of the gasket.
4. once inside. notice a round circular object on the base and a small oval shiny gold copper piece.
5. For whatever reason the shiny copper piece has shifted and does not make contact with the tiny little springs there are 2 if you shift the base to make contact with the gold piece the op en goes away and watch is back to normal.
6. the fix is move this little piece back to where it belongs. i got lucky and the glue still held when i firmly moved it to its original location. super glue came to mind if it wont stay where it belongs.

7. gasket orientation and cleaning out the gasket channel is a given i used welding tip cleaners to do the intricate work. under the bands are very grungy. mine is about 5-6 years old. reassemble the way it came out.

if your battery is good and you get this op en look to your display for whatever reason this worked for me and if casio uses this as a warranty or warning of water coming in your watch it was a STUPID DUMB IDEA. those springs should be solid state and the watch is useless until it is fixed no light, no baro, no alt, no comp. notta and no buttons work. there is no reason whatsoever that this shiny copper thing shifts but it happened to me and my watch is working and my battery has had H or full power since day one.

Hi, Obviously you need to roll the time 12 hours ahead. If the watch doesn't receive the Atomic signal properly at first, go to page three of your manual, and try doing it manually following the detailed procedures there.

If you don't have the manual, get it here:

Take the four-digit (3070) module number from the back of the watch, enter it, and download a PDF of your watch setting-instructions/manual.
I hope this helps you. Thanks, Bill

mcdevito75 here, Many Casio Watch Models out there, I'll bet however your Casio is displaying say 1 AM rather than 1 PM as it should if the time is indeed PM after 12 noon, if so, this is why the date is changeing at 12 PM rather than, 12 AM simply re-set your casio and make sure the time of day is set at PM for time after 12 noon and AM for time anywhere before 12 NOON. Also, as you set your Casio, look for anything that may give the hint of Military time, this may be revilled as 12 hours or 24 hours, if you have anything like this, make sure it's set for 24 hours. If you have additional problems, visit a small watch repair shop in your area. Again there are many, many Casio models out there and without your watch with me it's difficult to be more accurate.

There are so many applications use of the manual will be mandatory.

Use the four numbers on the back of your watch and you will have a PDF version of your instruction manual.

Hope this tip helps

Hold down mode (bottom left) for about 5 seconds and it should come good.
Good luck

and go to the section "Adjusting the Home Position"

This is a "calibration" procedure to get the motor of the analog movement back to the home position of 12:00. This worked for me, after replacing the battery.

Note that in this procedure the hour hand does not move separately, but moves with the minute hand. So to get the hour hand to move, you have to let the minute hand spin a number of times until you get the hour hand up to twelve o'clock.

thats because analog watches don't know the difference between AM/PM. First reset the time, moving the hour and minute hands another 12 hours will let you know exactly what mode its in (am/pm) first allowing you to set the date correctly.

Alarm Setting:

1st: Press the mode button to go to the alarm screen.

2nd: Press the adjust button for the time to flash

3rd: (For the Hourly Alarm) You can adjust the time here while it is flashing by pressing the start/stop button. Cycle through this until you have the time you want. The setting will have the P in the left side of the screen for PM (night time).

4th: (For the Daily Alarm) Do steps  1-3 once the time is flashing use the Mode button to cycle through to the date field of the watch. Once it is flashing you can use the Start/Stop Button to chose which date Month/Day, after chosing the month just press the Mode button once more to go to the day field.
