According to Rex B "":
I bought a Casio watch a few years ago. I liked it until it needed a
battery. It was impossibly to user-replace, and the regular
watch-battery kiosks would not touch it. It's in the junk drawer.

I have a Casio "Twincept" (mechanical hands plus a LCD digital
readout on the crystal) which I got perhaps fifteen years ago.

Access to change the battery requires a tiny Phillips
screwdriver to remove four screws in the "corners" of the back plate,
and then a tiny straight blade to release the clip holding the batteries
in place. (There are two.) They are easy to get, and when you have
replaced them, you have to short a pad on the circuit board to the metal
plate through which you access it (using the tiny screwdriver again) to
reset the logic. After that, you can again set the watch as usual.

I've changed the batteries about twice, IIRC -- once every five
years, so it is getting close to time to do so again.

The back plate (and screws) are stainless steel, and the body is
a black plastic (probably Delrin).

The band failed once, and I got a new one fitted by a local
jeweler (though I could have done it, he would not sell an unmodified
one, for whatever reason. :-)

Previous digital watches tended to have the case corrode after a
few years of summer perspiration. This one has had no problems.

FWIW, the model is "WR 50M", though I suspect that it is no
longer made.

I never have used the "store a phone number list" feature, nor
the "Alarm" feature (It is too high pitched for me to hear), though the
"World Time" feature has come in handy, it includes the ability to set
the time zone while on travel without disturbing your normal time zone
setting.

Now -- if it only knew enough to switch to DST and back at the
appropriate times -- or even had a button to allow me to manually
select/deselect DST without having to re-set the time, I would be
totally pleased with it.

Enjoy,
DoN.
