I could not locate a manual or instruction guide using the internet search of https://www.google.com

I did see a battery replacement video and source for a battery, as many questions on FIXYA are from people who don't seem to want to go to a watch repair or jeweler to replace a battery.

3. Gently pry the battery cover off of the watch.
4. Remove the battery from the watch.
5. If you are replacing the battery, insert the new battery into the watch, making sure that it is oriented correctly.

How to change a Casio watch battery:

1. Spread a cloth over your work area The cloth will help you avoid damaging the finish on your watch.
2. If necessary, remove the watch band Removing the band gives you easier access to the back plate.
3. Remove the back plate For some models this means using a screwdriver to gently pry it open, and others require removing screws. Keep small screws in a container to avoid losing them!
4. Take note of the rubber seal Sometimes they need to be reinstalled in the same orientation. You might even want to use a marker to make a small "match mark" before removing it.
5. Locate the battery It looks like a small metal button.
6. Remove the battery You might need to loosen (not remove) a small screw and slide a latch out of the way. For other models, it's as simple as popping open a strap that is stretched across the cell.
7. Install the new battery Make sure it's in the same orientation as the old one. They usually go in with the positive (+) side down.
8. Perform a reset Do this by touching one tip of the tweezers to the AC contact, inside the watch, and the other tip to the back of the watch battery.
9. Make sure the watch is working properly Carefully lift the watch to do this. Don't turn it over or the watch movement might fall out.
10. Reassemble and seal the watch Perform steps one through four in reverse order to reassemble your watch.

Best regards. Jewel

Hello
All you need to do is to try and get to a watch store and locate the type of wrist watch you need and go for it.Better still you could check it online before going to the store.
BEST OF LUCK

To reset the battery you need to locate the "AC" inside your watch. The AC terminal is a little metal spot (usually a circle and usually gold colored) on the inside of your watch. Looking at the inside of your watch the "AC" should be labeled, though it may take a magnifier to identify it.
It may be labeled simply "AC" or it may have an arrow pointing to it. Once you locate it use a pair of tweezer or a paper clip and touch the battery and the AC together for a few seconds and release; you may have to do this twice. This will reset your watch an give you the ability to correctly wet your watch.
