1) How do I know if my wristwatch has a replaceable battery? I bought this Casio at Walmart and the watch kept great time but the battery died within 3 months. (I see no way of opening the back.)
2) How do I determine what size replacement band to get for this watch?
That's a Casio 1330. It uses a SR920SW battery. The back unsnaps..... but not easily.
Unfortunately Amazon has that watch for $11-15 and the battery itself will be at least half of that.
Thanks a lot, Pete. The watch cost $15 at Walmart, but I like it because it's really light and has an easily readable face. I looked on Amazon for the battery, and it looks like five of them are only $4.48. https://www.amazon.com/Maxell-SR920S.../dp/B0014WUYMW
Which would definitely be worth it to me. The question now is getting the back off. My Timex has a little ridge that a thin screwdriver will pry up. I don't see anything like that on this. maarkr suggested unscrewing. I'll give that a try but maybe you have another suggestion for getting it off?
Check that. I found a great video on Youtube. https://youtu.be/BdD3_gGvop8
Should be pretty easy. Thanks--the model # let me find the video.

Reason: found additional info
Just a little follow-up in case someone else sees this. The battery size for the Casio 1330 is actually SR626SW. The SR920SW is too big. The batteries were really inexpensive. $2.25 for a five pack and free shipping on Amazon. I'll probably use the SR920SW on some other watch, so nothing is wasted. Those were inexpensive too. Same sort of price range and free shipping. (And I used one of the additional sellers, which were much less than "fulfilled by Amazon" sellers. Specifically I used Bellatrix Industries and I got the batteries fast and they were due dated 2024.)
2024 I think that means those batteries are already 6 years old as batteries usually have the "Use by" date 10 years after they are made.
I had a nice Casio watch it used a CR2025 I tried to replace the battery myself but I ended up destroying the watch as I could not get the battery out, I'm more used to the kind of coin cell holders that PC system boards use (the type where you press the end and the battery pops up) this had some kind of weird clip holding it in and I could not get it to release.

Ah, no wonder they're so cheap! Still, I got it in there and working. (Thanks to a very helpful Youtube video.) Too bad about the battery being so tricky on your CR2025.
I get noise - hissing sound. Random. Ok for months, then every 2 or 3 days, then OK for weeks..There's a box on the outside of the house where I can plug in a phone. There is no noise there. So problem is inside the house. Picking up noise somewhere.
My [B]incoming[/B] shielded cable is grounded. Also, there is a terminal block beside my breaker panel to which these incoming 4 wires (and ground) attach to this block.
I have 4 phone cables coming down from the ceiling joists to this block. I plan disconnect one phone line at a time to check for noise. Slight problem doing this:
All reds are on one screw of terminal block. All greens on another screw. All yellows attach to the same terminal as the ground.??? All blacks from my 4 phone wires are all connected together with a wirenut. Blacks are not attached to terminal block.???
SO, I'll have to disconnect [B]everything[/B] to separate the 4 lines.
I realize the yellow and black aren't used, but why are the yellows connected to the ground?
After I separate everything, should I re-connect the yellows to ground? Why?
Is this weird wiring causing my noise?
Yesterday I found a [color=#202122]Ericofon by Ericsson, also called the Cobra, the other day and bought it. A friend still has a land line (running through his cable phone company box) and I plugged it in. Works great, made a call and everything. [url]https://en.wikipedia.org/wiki/Ericofon[/url]
Honestly I bought it to sit in a cabinet and look cool, not to use. However like the old black and white TV I would like to be able to show say my Grandson (without having to find a working land line) how it works.
Thus I am here. I of course have internet and a cell phone but I gave up on TV years ago.
On line I have found a few things like this: "[/color][color=#000000]magicJack HOME VoIP Phone Adapter (K1103)" I doubt this will work because the phone is rotary.
Does or did something exist that would convert rotary signal to pulse? (not sure what the push button hones were called) Or do I just have a relic of the past. Willing to look find and buy what is needed but don't know what that is.
Thanks[/color]
