SOURCE: battery replacement for a G-shock.

The reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, as well. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.

SOURCE: how to get casio sea-pathfinder working after replacing batteries

On my older pathfinder the AC arrow pointed to a hole in the white plastic shield below with 4 "brass" dots. Connecting these to one of the batteries in place restarted the watch.

SOURCE: I am replacing the battery

Hi,

it is a tricky way but it can be done...
remove the clockworks completely (that's including the plastic casing) from
its housing
separate the plastic frame from the clock
remove the little screw you spoke about earlier
look at the edges of the big battery clip holder, they latch to the clock
housing at three locations,
pry-off the cover plate...Presto battery can be removed. Before you
reassemble in reverse order make sure that the pushbuttons in the housing
can move freely, lube with light oil if necessay or remove them completely
to remove sweat and dirth

SOURCE: Battery Replacement

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). It is embedded on movement. 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.

Do not forget to rate, please.

SOURCE: casio illuminator, w-94h

There is a tiny spring that must make contact with the back cover plate when you screw it back on. If the spring is missing, the piezoelectric buzzer will not work. The tiny spring is located toward the upper right in this photo of a Casio W-94H watch, directly underneath the "C" in CASIO that is etched in the metal. Note that the word CASIO is upside down in the picture, so if you can't see the picture for some reason, the hole for the tiny spring would be directly above the "C" in CASIO.

When I press light buttopn in the middle the display goes blank


This sounds like a simple battery replacement. Depending on how low the battery is usually pressing the light button and the display goes dim or blank is a good indicator of this. Takes a CR1616 battery and be careful of the spring inside and make sure the seal is in the correct position. You will need to touch the AC button and the back of the battery with a pair tweezers for a couple of seconds to reset the watch. Put the case back on and set the watch thru the functions.

CASIO SPF40 battery replacement


"AC" means All Clear. This terminal should be marked somehow. Use a magnifying glass to get a good look at what you are working on. My Casio had an arrow pointing to four copper leads. I used a paper clip to connect the AC terminal (I just picked one of the four) to the + side (usually the "up" side) for a couple seconds and my Casio Sea Pathfinder model 2273 powered right up. See the following link for more guidance.
