20 Most Recent Casio Twincept Databank ABX238BV Wrist Watch Questions & Answers

Do not lay the tweezers across any contacts as you may damage the watch.
First you need to examine your watch movement and find an AC point (contact). Use an eyeglass, as the writings can be very tiny.
When found, touch an AC point with one arm of tweezers and battery+ with another arm simultaneously.
Some watches needs to do that twice, so, to be sure, do that twice.
If you are not comfortable with tweezers, you can use a thin wire, connecting one end of the wire to AC point and another to battery+.
Each shortcut should last for 3 seconds.

Question edited for clarity. Question moved to Casio Watch, from Office Equipment. Pressure backs need a tool to unscrew the back and the gasket should be checked and greased. Best advice here https://www.fixya.com/support/r27181038-changing_watch_batteries ..

It is likely that the battery is depleted sufficiently that the sound feature can't work. Take it to a local jeweler for battery replacement service. https://www.fixya.com/support/r27181038-changing_watch_batteries ..
