I have an old casio Pathfinder (1376) PRT-50, and I replaced the battery and it says OPEN, but I'm not sure if the battery is the correct one, because I lost the original, just in case I put a Maxell CR2016 3V, If anybody knows about this, help me, thanks...
I know the secret that CASIO is hiding behind this thing. If your watch shows "OPEN" then you don't have to go to a CASIO retail store. You don't have to send your watch with money to CASIO or go to an Authorized CASIO Service Center. I know how. Just send me an e-mail to [email protected] and believe me you'll be happy to know the "SECRET" an get rid of this annoying "OPEN" over with. You want this fix! Than don't wait.
You have the right battery. You have to reset the watch after replacing the battery. On the movement there will be a "AC" or a + sign. Take a pair of tweezers and touch one end of the tweezer to the sign and the other to the top ( the positve) of the battery, let it touch for a good couple of seconds, and do this one more time just to be sure you make good contact. That will take care of that "open" If you find you still have a problem,or any others, feel free to ask, I will be happy to help. Good Luck!!!
Casio 2471 Pathfinder, replaced battery, reset according to instructions and no matter what I do it just still says open
Sorry guys. After reclosing it twice, it worked. Could have had something to do with the little springs (they came out and I put them back wherever they would fit). Thanks.
Choose a quiet, well-lit room where you can replace the battery in your Casio Pathfinder watch. Prepare a table, desk or other clean, flat surface where you can perform your watch repair. Put down a soft cloth or piece of craft felt to protect the face of your Casio Pathfinder watch from being scratched during the battery installation process.
Set your Casio Pathfinder watch face-down on the soft cloth or craft felt. Use an optical-sized Philips screwdriver to remove the four screws that secure the watch back to the body of the watch. Set the screws aside, but don't lift the watch back.
Slide the watch back off of the body of the watch very slowly. There are three important springs held underneath the watch back; it is essential to remove the watch back slowly to avoid losing them.
Lift the three springs out of your Casio Pathfinder watch using a small pair of metal tweezers. Take note of the length and placement of the springs as you remove them. Set the springs aside with the other disassembled watch components.
Take the black rubber protective disk out of your Casio Pathfinder to reveal an identically-shaped white plastic disk. Remove the white plastic disk and set it and the black rubber disk aside. Use your metal tweezers, if necessary, to lift out the rubber and plastic disks.
Release the battery strap that holds the battery in place in your Casio Pathfinder watch by pushing the battery strap latch to the left. Remove the old battery from your Casio Pathfinder using a pair of small plastic tweezers.
Pick up your replacement watch battery with the small plastic tweezers and insert it into the battery compartment of your Casio Pathfinder watch. Replace the battery strap and push it gently with the tip of your plastic tweezers to snap the latch in place.
Touch the "-" and "AC" terminals on your Casio Pathfinder watch with the tips of your metal tweezers for at least two seconds. This helps ensure that your watch will work properly once reassembled.
Put your Casio Pathfinder back together to complete the new battery installation. Start by replacing the white plastic disk, followed by the protective black rubber disk. Use your small metal tweezers to replace the small watch springs in their correct locations. Replace the back cover of your Casio Pathfinder, insert the four screws and tighten them with your optical-sized Philips screwdriver.

I have the same problem. But connecting AC-contact to +3V does not solve the problem. The display stays for days in "OPEN".
EPROM failure ?
I, too, have the same problem, and connecting AC/+3V only temporarily (for a few seconds) makes the display return to date. It then immediately returns to "OPEn". The two tiny springs fell out and I am not sure which holes to return them to, and think that this may be related to the problem.
I touched the ac and the +, put it back together and mine says "close" Thanks for the help
I can't find the AC and what is the movement?
Thanks
