Normally gasket has not to be replaced after battery change.But all depends of the use.For example if you wear the watch in salt or pool water and never flash it with fresh, clean water after,it may be a cause of gasket wear.Remove the back cover.Replace all 4 batteries(be sure first that you can do this with extreme caution as all parts are tiny).Remove gasket.Check gasket condition(cracks,gasket too dry and hard).If gasket OK, apply a small amount of special silicon compound for watch gaskets,all around and to all sides of the gasket,put it back in place,carefully.Be sure that gasket is set correctly all around.Put the back cover in place and screw with much caution (not too tight-a little resistance).Your watch now normally is water resistant.But if you want to be 100% sure,take the watch to a serious repair center where it will be tested under pressure ( 3 Atm average).Then they will tell you if your watch is 100% water resistant.

  • 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.

  • 2

    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.

  • 3

    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.

  • 4

    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.

  • 5

    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.

  • 6

    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.

  • 7

    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.

  • 8

    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.

  • 9

    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.

    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

    The only way is to pull out the battery and I dont think you want to be doing that.

    Casio battery changes are quite tricky.If you look closely at the watch module there is a place for the battery and a v-small depression usually circular on the silver module .There will be the letters AC in small writing.You need to touch the depression AC and the battery at the same time with a conductive tweezers.This shorts the module and re sets the watch.Make sure any seals go back in to protect from water/dust.

    how do you replace a battery of Casio Pathfinder?

    Casio PRG-40T-7... | Answered on Aug 01, 2010 | 1,529 views

    mcdevito75 here, My best advise is to see how the other 2 springs are situated in the watch, then simply follow suite with the 3rd spring. BE VERY CAREFULL THOUGH AS< ANY OR TOO MUCH RESURE ON THE CASIO DISPLAY WILL RUIN IT. If you can"t find the spot for this spring, look for a small watch repair shop in your area for help, it"s better than ruinning your watch.

    mcdevito75 here, I've never heard of a tide clock or adjustment or timeing for tide cahnges. The tide changes every 6 hours with 45 minutes at the end of that 6 hours rest you could say before the change of the tide. Refer to your local newspaper or fishing supply outlet for tide schedule.

    mcdevito75 here, I'm figureing you"ve changed the battery, Pressing the MODE button should re-start your watch. If you didn"t change the battery and your watch just stopped, try pressing the MODE or any button to re-start the watch. If nothing, change the battery and repeat the above instructions.

    Indeed the buttons (pushers or pusher contacts) may have been jammed internally. The are a small piece of metal which is pushed my a cylindrcal rod (which you are pushing the outer part of it into the pusher contact).

    Sometimes the pusher contact may have come out of alignment. or did you change the battery yourself? did you a/c it properly? (metal tweezer from the a/c with the battery)?

    Hope this helps or sheds so light on your situation
