Battery for me this watch lasts for ten years, but I say change it before because the light in the display becomes weak.

I have a Canibal watch where it'sworks are similar to what is shown in the video.

Great instructions on how to replace coin battery in f-91. Also thanks for saying we need to make sure the silver buttons need to be pressed out. Am interested where you got your ctoss-point, flat-head screwdriver from. Very handy tool. BTW I have a f-94.
Hi! Love your vids. I am having difficulty changing this watch buckle and the strap retainer, I can't seem to push the spring bar to release them, and i searched EVERY where to find if anyone did it before on this watch but no one has. Do you know how to do it? If you do a search, no one has it on TH-cam thus far.
Would never touch the digital display with my bare fingers, if I can help it, as you'll very likely grease it up that way. Would also be sure to wipe it down with a lint-free cloth before reinserting it in the case (not all of us have the luxury of replacing watch batteries in a 100% dust-free clean room...). Oh, and as others have mentioned, you screwed the caseback on upside down.
Many problems with what he did, first, he touched the screen many many times. And second, I cant believe he didn't notice this, but he put the back upside down. :) Good video though.
th-cam.com/video/MwnjTBURH7Q/w-d-xo.html Bend the gold thing right there down so it doesn't touch the back of the watch face. it will disable the alarm too.
But a service center costs more than the $10 watch is worth. So it's better to DIY the battery replacement and just buy a new watch (and use the old one as a backup or spare).
You didn´t tell most important. Watches are not working after battery replacement. You must put them back into case, screw the screws and after that you must press buttons to light up the LCD.
Got my old F-91W beeping again. I'll be back in another 18 years!
lmao
how you made it. i have the same prob. in mine?

Thanks for such a clear and simple to follow demonstration!
It's probably cheaper to just get a new one but after you've had a 8 year streak with this 10 dollar watch you get sentimental lol.
Its not. A 5-pack of these batteries costs about 5 dollars
These watches cost $33 in my country now. Insane inflation

These watches are 30-40 euros in my country. Battery costs 1-2 euro.
Actually I found these watches on ebay for £3 (including postage); they are not real casio but work just fine otherwise...
You save my day. Now I dont need to go to the watch technician to change my legendary f91w. This is TH-cam supposed to be.
youtube is eating up lots of jobs it seems

Just changed the battery following your tutorial, everything perfect!

If possible, the gaskest should be re-greased with silicone-based grease. Other than that, nice step by step tutoial vid.
Thanks for the info! I didn't knew about the re-greasing.
TipsTricks
No problem! Re-greasing the gasket is necessary, otherwise the watch might loose it's water-resistance/tightness.
@@ET42Driver I read on a forum that if you don't have access to silicone grease then using vasaline is better than nothing
Can I re grease the gasket using coconut oil or semi synthetic litium grease ( usually used for greasing bearing on bicycle)?

very helpful video! i will change my battery when it runs out. does replacing the battery cause the watch to lose its water resistance?
Clear demonstration
Great tutorial, it really helped me. keep it up! 👍
thanks :)
Thanks I can now replace my battery.
After you changed the battery do the WR change? Becaused you already open the case??
possibly the gasket probably need replacing but parts for these watches are almost impossible..need to buy a new one

Great tutorial, thanks!
I've got a casio w215h. Its batery can last up to 10 years! The battery of my fathers f-91w can last 15 years!
My f91 battery is getting weak after 28 years
some sites say if it is made in Malaysia it is a fake..mine is made in Malasia..is it original?
Original watches are made in Japan, Thailand, chaina or maybe Malaysia
Thanks a lot
Gracias por el video 😊
Will there be any effect on the waterproofing ?
I have other digital watches and just cannot get the screws out. The Casio watches though look much better quality screws to remove?

Is it an old one? Maybe the spring bars springs has rusted up.

Siempre recuerden que las baterías no se tocan con la mano ya que podemos quitar energía de la misma
" or dislike it, if you dont like me",. lol, not related..

@@simonmesure6863 agreed
What size Phillips head? #0 or #00?
I did a battery replacement for the f91w I removed the white tape now it does not have any sound.
If my Casio is really new but I wanted to open it up, do you recommend still re-greasing it or should I be fine for a while?
Would never touch the digital display with my bare fingers, if I can help it, as you'll very likely grease it up that way.
Would also be sure to wipe it down with a lint-free cloth before reinserting it in the case (not all of us have the luxury of replacing watch batteries in a 100% dust-free clean room...).

hey good video i have one of these at my house its a pretty good watch
Thanks! :) I got many watches but this one is still the one I choose for most situations.

hi may i know the use for the white sticker?
yes i am also wondering its purpose may insulate the battery from the metal back ?
Many problems with what he did, first, he touched the screen many many times. And second, I cant believe he didn't notice this, but he put the back upside down. :) Good video though.
What to do with the very little spring? I don't know where it came from...?
what kind of battery does the casio w217h watch use
Good job ⌚⌚⌚
I order for one to replace a battery of one of those Casio watches it had to be purchased by your great grand pa.
hello i was trying to change my casio f-91w battery somehow it lost its beeping sound after I finished, do you know a way I could regain the sound?
normally set in the alarm section..google.Mine stopped beeping too and settings did not help.
Great thankyou
0:38 Made in Malaysia
greetings from Malaysia :)
i did read see on another site that Malaysia watches were fake.Hope not ..mine is mad in Malasia ..better than China where they are made now,
Thank you.
I've seen some videos where the watch need a reset button or else it won't work ?
Mine worked without any need to press any buttons after replacing the battery.

Try getting a grip on the screw using pliers and then turn the screw until it comes out.
@@Brainman_2331 or use flat tweezers

Perfect,thanks
If I will change the battery of my watch after that does it take the water inside..?
Good video
3:53 Reverse cover mounting !
What would you have to remove to get rid of the beep completely?
Pablo Andres speaker probably
There's a small spring that conects to the back of the watch. To stop the speaker you need to remove it.

Best and good batary is what
Nice. SOng name pls
Can you buy the gasket any where. Mine has broken.
no ..cheaper to buy a new watch
ótimo, vc é 10

God these LCD screens are so delicate
Where should I find a new resin strap for my f 91w .......after 3 years
parts can be expensive if you can even find them ..cheaper to buy as new one
I love casio f91
does this affect the water resistance
Yes it does affect the water resistance. You should take it to the service, so they can check the water resistance.
But a service center costs more than the $10 watch is worth. So it's better to DIY the battery replacement and just buy a new watch (and use the old one as a backup or spare).
You didn´t tell most important. Watches are not working after battery replacement. You must put them back into case, screw the screws and after that you must press buttons to light up the LCD.
What's that white square paper stuck on the watch?
yes ..perhaps insulte from mental case cover?
Your bezel cover is put reverse . Could not alarm sounds .
What song is this? I hear it everywhere
TH-cam has a list of some free songs you can use in your videos without getting in troubles. This was one of them
When i press "mode" button, the current time resets, why? Help!

I got a f-14 casio that works on the same principle unfortunately after changing the battery it’s not working so it’s dead
