3 months on of normal 24/7 use and no problem to report.
If it ain't broke, don't poke: replacement battery and disconnected
spring contact remain on the outside.

I have a Waveceptor, don't know the module number, but it's "solar
powered". I don't use the backlight much, but what I remember is I got it
in the spring of 2006, and it's still running fine on the first battery.
At one time, I accidentally activated the function where if you move the
watch at a certain angle the backlight comes on, no need to press a
button. Before I figured out how to reset that, the "battery indicator"
was down one bar, I think the only time it's never been at "full power".
I paid about 20 dollars for it, wanting the "atomic watch" aspect, but
it's nice not to have to change the battery. I know on my previous Casio,
somehow the replacement battery lasted a very short time, and then the
strap broke, so I abandoned it, rather than buy a second battery so soon
on top of needing a new strap.

Look for "Slide Base T6.8". For example SM2420G (24V 0.5W) are in stock
at Mouser.

T-2 bulbs measure 1-11/16" in total length. You are looking for 24C1
Telephone and Indicator bulbs according to my old light bulb spec guide.
They are rated as 0.06 - 085A, 1900 Footcandles, average cold resistance
33R, hours life = 5000.
 
I might have those in my ancient parts stock if you can't find them
elsewhere.
 
At least you know what you are looking for now!

Last time I had one of these fail, I soldered a led in
the metal part.
