I have a Casio WSD-F20 and when I got a new phone, I did the mandatory reset to pair it. This resulted in the known bug: the watch would fail pairing at about 20%. Because the watch was still covered by warranty, I had it "repaired". I am not sure what they did (probably exchanged the motherboard), but I was able to finally pair it to my know phone.

2 years later I have a new phone. I have not touched the Casio WSD-F20, but it sucks using it with the "wrong" phone paired.

My question: does anyone know for a fact if a "repaired" Casio WSD-F20 will brick again when trying to pair to a new phone?

Hey Y'all! I was thinking it would be good to start a specific subreddit for Casio Watch sales and deals found online, so I started a new subreddit! Check it out, make some posts, let me know if there's anything I should add/change. Totally open to suggestions, thanks!

I always forget to stop the workout and left with irrelevant data. Is there a way to edit the portion I forgot to stop out?

Anyone else have this issue?

I recently decided I want to wear a watch for the first time in near 40 years of being alive. But its cause of all the cool features! These Casio pro trek options seem awesome but hard to find? Maybe discontinued? Replaced by g shock? Also where I have found watches for sale (in Canada..) Don't give much info

So I'm wondering if you all may know of a model that has...

Alt/bar, temp, compass, and step counter/heart rate. I've found the first 3 and the ladder 2 but haven't been able to find them together.

I don't care about Bluetooth, and I'd prefer analog for telling the time at least... Does one exsist?!

Thanks for you help, just getting into this world and Casio seems to be the best option after a limited amount of sesrching

I’ve been using an Apple watch for a while now and the battery is about to give out. Might last a few more months. I don’t really use the watch for a lot of activity tracking. Just some walking, jogging and if the weather permits some swimming laps. I’m planning to switch to the G shock h2000 series once the Apple Watch gives out.

My main question is: I love the notifications, reply to msg, accept teams meeting features on my watch. Can the Casio do an equally good job?

Sadly, replaced my iPhone with the newer one recently. Couldn’t bring myself to buy the S24 ultra and the pixel isn’t there yet for me. So, it’s iPhone only for now.

Ps: I do keep an android phone, and if the Casio can do all the notification stuff fairly well on android, it could tempt me to invest in a pixel 9a as it comes out.

Hi all,

I mostly used my F30 model which still lasts 2 days (after more than 4 years). So I kept my WSD-F20 in the drawer, charged it occasionally to preserve the battery life (🤔 not that often as it needed to be charged).

Well I came back to that watch to wear it more often, but I ended in poorly one day until it ran out of power.

I decided to spend it a 2nd life and bought a new battery from here: https://www.minott-center.com/sony-batterie-lithium-casio-smart-outdoor-watch-passend-fuer-wsd-f20/a-36383

... and replaced the battery today following this description ... https://www.reddit.com/r/casiowsd/s/GfNx7ckW52

... or better watch this video: https://youtu.be/TrBOLU3F2Ro

Quite happy now and it seems to be reborn with the power of a new watch. Will keep you updated with the final battery life.

Hi all,

I just stumbled across a website, explaining how you could install AsteroidOS on a WSD-F10 or WSD-F20.

But first of all ... ALL YOU DO IS ON YOUR OWN RISK (I haven't tested anything described on the linked site)

What is AsteroidOS? Seems to be an open source project to get more privacy onto your smartwatch. ( https://wiki.asteroidos.org/index.php/Frequently_Asked_Questions_(FAQ) )

Note: It might not provide the comfort you are used to have with WearOS. Also you will lose the Casio apps on your watch.

So only try this (on your own risk) if your watch already has issues to pair with any phone and is unusable. So in case you have nothing to loose.

Important! The following site describes how to CONNECT YOUR WATCH VIA USB BY CABLE! ... yet you should be a technically skilled user, but at least there's a way now. ( https://wiki.asteroidos.org/index.php/Koi/Ayu )

Maybe you could reactivate your watch by finding some ADB commands via USB cable. (I have only less experience with ADB)

Else you could try to install AsteroidOS to have at least a simple smartwatch. ( https://asteroidos.org/watches/koi/ )

Not sure if this all will work on an already reset watch without developer mode switched to 'on'.

But if I had a bricked watch, I would experiment based on these links.

Anyhow, if you try to follow these instructions, please share your experiences in the comments.

Good luck, Woolve

I can barely see the screen / menus in direct light - the oled is fine of course but it only does one watch face .. any recommends for other watch faces or settings ? Is at max brought and font -just cannot see in direct sunlight…

Thanks for any proffered faces or settings ?

Be ideal if could e-ink all but can’t seem to do that .

Any ideas welcome

Hi, I hope you can help me, I’ve been trying to connect my Casio F20 to my android and ios devices but I got the same error on both and I don’t know what to do.

Hi All,

I have recently bought a Casio G-Shock GBA-900 and currently using iOS 17 (the latest software)

My watch should have the capability to alert me for notifications I receive to my phone. However, I only receive notification of calls. I have paired the device to my friends Samsung and it seems to work fine and he receives all notifications to the watch. The following are the troubleshooting steps I have taken:

1. Unpaired device and reconnected
2. Ensured the Bluetooth connection is set to “sharing system information”
3. Allowed all notifications from the app and allowed location services
4. Restarted app
5. Did a factory reset on the watch

no luck after all of these steps. If anyone has any information please do advise as this is driving me crazy. The watch itself is amazing but I want the ability of receiving notifications to my watch.

Hey everyone! I recently found an F20 model my dad left while cleaning, and I wanted to try and use it. I have the charging cable and everything but when it charges it gets stuck on this screen shown on the picture. Is there anything I can do to fix it?

I guess I somehow hurt the barometer module while replacing the watch's battery, because the watch keeps complaining about it.. I traced all connections and everything looked OK, even looked at it under a microscope :) But still no height or barometer readings and the watch gives a warning every few minutes about a problem with a sensor. Any ideas where I can find a replacement pressure sensor?

​

TIA

Hi.. My WSD-F10 started giving a Sensor error from time to time.. It might have started when I replaced its battery (ahem). It works for a while, then it complains.. When that happens the barometer and height pages show dashes ---- instead of real values.

I opened it up again and re-seated the ribbon.. It seemed snug however. I'm wondering if it's software related, as the watch did a software update a few days ago..

Did anyone else get Sensor Errors like that?

​

Hi. I'm using my wsd-f10 fine. Wear os app connects and works well. However the moment setter just crashes. It says setting up watch for about a minute and then crashes and exits.. is there any solution to this? Thanks.

As the title says, I have some issues with the units displayed on the watch. I want to see Celsius but it shows only in Fahrenheit. I can't seem to find the settings to change that neither in the app nor on the watch.

Any help would be appreciated! Cheers!

Already connected my watch using this ADB 'hack' (https://www.reddit.com/r/CasioSmartwatch/comments/zwlweg/casio_wsdf20_and_android_13_phone/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=1), but not 100% happy due to some play store issues on watch.

So I went 'all in'!!

-Unpaired and deleted watch on phone. -Reset watch. -Reconnected watch with WearOS by regular setup process.

... and SUCCEEDED!

Don't know why others were bricked and not mine?! Maybe a recent WearOS fix? Maybe only some F20s are affected? Maybe due to AndroidOne on the phone? Maybe because it has been connected to this phone before through the ADB hack?

Don't know. AMA if you consider to switch your F20 to a new phone too!

Note: No warranty it works on your F20 too!

PS: My phone is a Nokia X20 running plain Android 13 (Android One) and is still getting regular updates. My watchs model no. is 20xx, so I guess quite a low number (=earlier model?).

Hth!

Cheers, Woolve

Hello folk

I was considering buying a wsd21hr but I am really not sure if it is still worth buying after reading so many reviews about performance / updates issues, do you think it is still worth the 300$ or should I wait for newer version that is more compatible with newer Android / wear os?

Thanks

I Had Issue with my F20 PRG,

when the cable charger plug in to the watch, indicator lamp not bright as usual (Red Light ), and now my watch is steady on the digital monochrome condition, but if i plug back the charger, its only just show the battery picture.

i don't know how to fix it, maybe it because the battery is drop or just the cable need replace

PS. a few times i used the USB port in My Laptop to charging the watch, is it the problem cause ?

Please to help, thank you
