Your watch is a solar powered watch and normally you don't need battery change .Nevertheless,if (as it is an old Casio model),you are convinced that battery is the cause of your problems,then replace.
1) You have to be absolutely sure that you are able to carry out the procedure.
2) IMPORTANT!! Pse note that the specific battery IS NOT an ordinary battery as it is rechargeable.DO NOT TRY TO REPLACE WITH AN ORDINARY ONE.RISK OF EXPLOSION on your wrist.+total damage of the watch.New battery has to be exactly the same with the old one (ID.code).Can be ordered on E-Bay,I suppose.
3)TOOLS:Watchmakers screw drivers + philips small size screw driver (for backcover screws) + watchmaker tweezers + 2 finger rubber gloves.
Turn the watch upside down and carefully remove the four screws (try not to loose them).Remove the strap if needed.Gently remove the back cover.Pay attention as there must be 1 or 2 tiny springs embeded on the mechanism.Keep them in place and try not to loose them.You have to remove the plastic cover (pay extreme caution to the spring/s) in order to have access to the battery.Unlatch and remove (if needed) the battery holder ( if can be removed-remember the position to put it back correctly).Take out the battery and check for possible leaks.Check the battery compartment cleaness.DO NOT TOUCH WITH BARE FINGERTIPS THE CONTACTS OF THE BATTERY COMPARTMENT.DO NOT TOUCH THE NEW BATTERY ON BOTH SIDES WITH BARE FINGERTIPS.Use the finger gloves.Put the new battery in place (do not force) and secure back the battery lamina holder.There is a AC(All clear-reset) contact on the mechanism.Using the tweezers touch one end on this contact and the other to the metallic body of the mechanism.Lift the watch very carefully(as it is,upside down-without disturbing spring/s) and check if display is activated.By paying much caution put back the plastic cover correctly in position PAYING CAUTION TO THE SPRING/S. Clean up the back cover,gasket,and gasket furrow from dirt as good as possible.Check the gasket condition.Replace if needed.Apply a little amount of special gasket silicon compound all around the gasket,both sides.Put the gasket in place.Put back gently the back cover and screws in position.MAKE SURE TO POSITION THE BACK COVER CORRECTLY(in place and not upside down).Press it gently when in correct position before you screw.CHECK ALL AROUND FOR CORRECT CONTACT. DO NOT SCREW TOO TIGHT,DO NOT FORCE.Screw with fingertips until you meet resistance.
I hope this will help.

Thought this would happen when I sent you a request to help me simply change the analog time on my watch.
Your repsone to free suppor tis asking me to enter into a arrangement that requires payment.
I've solved the problem from another site free of charge.
I'm very disillusioned with the way you promote your site and will definitley recommending to others to stay clear of it.
COmes across as we can help you free of charge but bottomline is that this won't happen.
Onlty wanted to know how I change the analog time on my watch - could go to the Jewler to do this free of charge - thought the internet would help but your company has prolonged the support immensely.

SOURCE: what watch battery do i need?
If you are asking for that, it means you want to replace battery yourself, and if you do, you will have to open your watch anyway. So, open it, take the battery out and memorise all the writings on the battery. This is the type of battery you need.
Do not forget to rate, please.
If I was wrong with my guess, then submit all the writings on your watch caseback and dial, please....and do not rate yet.

This may sound dumb but make sure the battery is in the correct side up. There should be a + or - symbol on top of the metal piece that snaps over the battery. If that's correct get a pair of tweezers and spread them open, and touch one side to the top of the battery and the other side down inside a little hole with ac marked beside it. That will reset the watch, and your display should come on.
