I was having trouble replacing the battery on my Casio STR-300 because the instructions were in Japanese. I'm glad I stumbled onto your video. Your explanation on how to do the AC reset saved me a trip to a watch repair shop. 🙏Thank you very much!
You just saved my beloved 2005 Casio Illuminator watch. I changed the battery and was very disappointed to see nothing on the screen. Then I decided to check Google and I fell on your video and tadam! Watch fixed and running perfectly! Thank you Sir!!!
Can't thank you more. this actually had revived my beloved Casio TS-200 that i thought was dead for about 9 years now. very much appreciated your help..
Thank you VERY MUCH! You were the only video presenter that mentioned "the little hole" into which you must place a pointed probe in order to release the latch. That made all the difference in the world!
Thank you so much! I was installing a battery in a Timex Ironman and there was no "AC" in sight, but I found the contacts and it worked... Thanks to you. Cheers.
Omggggg!! I went here because I want to know why it doesn't work after I replace my battery. Thank you very much! I thought I broke my watch because I open it and replace battery for 10x times and it didn't work, but because of your explanation about AC's, It actually work😊Thanks a lot!
I found my old Casio W-59 that I received as a present from my brother when I was in primary school in the very early 90s. I replaced the battery and thought it was broken because of the garbled display. I spotted the "AC" marking and your video explained what it did and its working perfectly find now! Thanks for the help.
Casio 950 Alt 6100..Batteries Plus Bulbs installed new battery, but couldn't make it start, so they gave me the battery. Watched your video and it's back working! Ac is the answer. Thank you 😊
Thanks for the video! I tried to replace the battery in my CASIO G7100-1V and the battery clip would not latch. After inspection with a jewelers loop, I determined that the white plastic housing that held the clip in place wore out. I have No complaints!, my watch serve me well for over 20 years on one battery ! Time for a new watch!
Thanks so much for the tip! I was changing a watch battery in my G-Shock and missed that vital step. You were a lifesaver my friend and saved my watch which had a lot of sentimental value.
Dude you just help me revive my 20+ year old watch. I just held on to it after being said it was unrepairable die to sentimental reasons. Thank you so much for bringing back a piece of my life
Thanks soooo much!!! After changing the battery I thought it was dead and I was just about the throw it in the bucket. I never new about the AC reset as I couldn't read the sticker. You have helped me massive... your a star.
You are a genius!! Thanks so much for showing how to reset this watch. I bought about 8 Data Bank Telememo 50's at an estate sale and I thought I was going to have to sell them for parts but now they all work thanks to you!
Thanks for showing me how to do this. Saved me a lot of money by not having to send away my watch to Nike who charge the earth for what took me 10 minutes
I was going to throw away an old Casio 53w after changing the battery and nothing worked. After seeing you video - I did the ac reset and it worked. Thanks!
Yes, its working :) I had not a label "reset AC after battery change" so after battery change, it did not work and then i found this video and yes, there is AC point. And its working again, thank you :)
Thank you very much, I followed your instructions and managed to replace the battery in my Casio Easy Rec but there is a spring very long and cannot locate it should go. It is really long btw, not like the other short ones, thick at the bottom and get thinner 🤨.
I have bought a new battery and I did that AC thing. Numbers appear although then I click any of the watch buttons everything disappears. Is there anything that could be done in this case?
I have a Casio [555] DBA-80 (using it daily) given to me brand new 1991 when I was very young. I have change the battery several times my self and it have been a pure hell every time to get it going with sometimes hours. About 2 years ago I happened to read a manual to a another Casio and saw it mentioned to put + to AC after battery replacement. Sure I had seen this AC pad the first time I opened the watch and was sure it was the clock signal for calibrations purposes or such. Used a tweezer and put + to this pad and the watch started immediately. I just which I had known this 25 years+ ago..
At last a clear video regarding the reset of the AC whichI imagine stands for Alternatiing Curent as opposed to Direct Curent which one would get from the batery ?
Is it normal for the display to be absolutely blank after battery replacement? My watch fell of my nightstand and I’m only getting slight flickers of life when I press around on the back of the battery. AC reset does nothing. I’m worried the module is damaged.
I was looking for help opening the latch. different watch, edifice with a sr920 battery which is under a cr1616 battery. Need to open just one latch to get at the small batttery. hope this video will help.
Hello, ive bought a casio cmd 40 TV remote watch! Its on the way to me. The seller said, that he tried to change the batterie by a keymaker/watchrepair store, but the watch dosnt turn on after battery replacemnet. Ive bought the watch anyways, because i think the watch is working, but they didnt knewed, that you have to short it with the ac and the battery. Am i right or this watch dosnt need to be shorted with the ac technique? Thanks! I mean is this wath fully funkcioning after you simple put in the battery or has the watch to be shorted?
@@theoverengineer Ok, the wath arrived! Put a new battery in and it works(old battery was put in upside down...no wondern it didnt worked :)))) ) Everything works except the calculator touch pad. TV remote ect all is working but not the calculator. I had this before on another casio calculator watch, where ive replaced the battery and some kind of "black rubber/plastic" piece flew out of the watch housing. I didnt knewed how or where to place it and from there on the touch pad never responded anymore. Here on tis TV watch i hadnt seen this "black piece"! Should there be one? Or what else could be the problem, that the touch pad dont respond? Ive did the AC reset succesfully and the watch showed 12:00. Thanks
Thanks for shaing you story.Not familiar with that part or calculator watches. That lost piece must be could have 2 possible functions. It could be part of the circuit, without which it stays open and not work. Quite possibly part of ground. Could also be an insulator, then without it you have a short on some of the circuits.
@@theoverengineer hello, ive researched! ITs called zebra connector! It connects the touch pad iwith the circuit. Iv opened up the watch and its missing. Made a photo of it: drive.google.com/file/d/1Rk-ks46crh6vXIKXlHnnitb3zJpQVLKp/view?usp=sharing
I have a casio databank db520, and after the AC, when i screw the backside on the display fades and comes back when i push a button and then fades again, what could be the problem?
Thank you for this video man, it was a big help for me to revive a Casio BP120 watch (I got it as a gift). I replaced the battery but the watch didn't work and then Ibtried to reset the AC and now it is working! Great work, keep going!
I’ve got a Casio C-80, I pressed the AC button before changing the battery, the watch stopped working, and I don’t know if changing the batteries and pressing AC button and the + will work, will it?
hi, ive opened up a springbar and took the spring out of it! Now my moon phase watch works like it should! Im so happy!!!!! Do you know if its possible to polish out little sratches from the housing it self? I had total succes on the glass. It looks new now after ife sandpapered it and polished it. But on the housing im affraid that the black will be gone. or is the complete housing made of solid black material?
Black phosphate coating on metal is cosmetic for corrosion prevention, it is a microscopically thin layer. Same thickness over plastics, for cosmetics or looks only.
a pair of tweezers didn't work so i used one end of the tweezer and the screwdriver i opened the back with. had to dispose of the plastic cover because it kept resetting the watch. thanks!
Thanks bro for your video.. Anyone can help, how to reset miyota 0s30 chrono ? I tried all buttons, connect with 🔋. Still dead, maybe my movement is really dead 💀 This is the movement : imgur.com/UCIxnXh
Nice picture. Does not seem to have an AC reset at all. Circuit might have corrosion under or around the battery. Between the (+) JAPAN and at the bottom of the hole marked (-) there should be 1.5 Volts measured when the circuit is complete.
Good grief, review your video BEFORE and AFTER you upload it to see IF WE CAN HEAR YOU ... which WE CAN'T! Edit the audio of your video's to increase the audio volume!

Here, AC = all clear
Thenk you very much! This allow me to change battery by myself!! :)

Is it normal for the display to be absolutely blank after battery replacement? My watch fell of my nightstand and I’m only getting slight flickers of life when I press around on the back of the battery. AC reset does nothing. I’m worried the module is damaged.
not normal. If the battery voltage is 1.3V or more, and the screen is dead, it's a big problem
Thank's! This helped me to trust myself and test AC reset. It works!

Thanks super helpful Ross NZ
can you use some wire to connect the speaker and the little metal where the spring belongs to? I have no sound on my moon graph watch
Sure, it can be jumped, make sure you have current going into the speaker first
hi, ive opened up a springbar and took the spring out of it! Now my moon phase watch works like it should! Im so happy!!!!! Do you know if its possible to polish out little sratches from the housing it self? I had total succes on the glass. It looks new now after ife sandpapered it and polished it. But on the housing im affraid that the black will be gone. or is the complete housing made of solid black material?
Black phosphate coating on metal is cosmetic for corrosion prevention, it is a microscopically thin layer. Same thickness over plastics, for cosmetics or looks only.
ok so if i would polish it down, then the layer underneeth it would be white plastic?
Will likely to be some color other than the surface`s black, plastics come in many color, most are white -ish.
Thank you for the tutorial!
Thank you for the explanation.. But on my watch it says hset and sub and then fades out am I doing something wrong?
is that battery up to its voltage?
Yea same volts as the old battery just not the same brand
Wish i could thumbs up 10 times haha had me stumped until i watched ur video :)
Thank you so much, you saved my watch
Going back 1995 just like hay😁
Thank you theoverengineer 🙏
thank you so much , i really happy for fixed my daddy"s watch.
Thanks for watching!

Thanks, it worked!
When I installed the battery my watch started working without the AC reset. Is that a problem, or is it fine?
If it works, don`t mess with it

GOOD, MAN !!!!
Sir help me. How to solv screen is fade Casio al-180 .sir pls help me

Some Casio watches (older?) instruct to touch the AC to (-). It must be similar.
Sure is
How to reset Casio a 230?
On my watch it says contact ac and (-) and you touched (+) on the battery
the sticker on the video indicate ac and +, mines are - too by the way
Most seem to say connect to + some say to -
Half of the battery clip broke rendering it useless. Gorilla tape to the rescue.
battery made in Indonesia? why people indonesian not make product indonesian
Tried all this and the watch won't get power. Now gonna have to pawn it off on some poor bastard
Can Anyone tell me the battery code?
What code? Batteries don't have a code.
@@theoverengineer the battery code is CR1620, I find it on watch store
ive NEVER had to do this with any digi watch.

Mine doesn't work 😭

You are wrong. It says touch with minus not plus

No corrosion, everything seems fine
Yeah, ... voltmeter comes to mind with 2 needle probes and a whole list of tech skills ...
