Thanks so much for this, one question I have is since doing this for some reason my light no longer works, the button still functions when setting watch up, but when on main screen it no longer triggers light. Any ideas what I may have done or how to fix? 😅😞
If the watch is new, I believe you should not worry about that. If you go swimming, you can look on Amazon or eBay for this gasket watch grease and take one with good feedback.
You know what I don't like about this replacement process? 1 - Lug removal (Casio's Fault): There's a user experience and engineering issue with the lug removal mechanism. They should have two tiny balls on both sides so you can use one standard tool to push from both sides and lift the strap up. This way, you don't damage the lug holes in the long run. Otherwise, eventually one hole is going to get bigger than the other. Not only that, if you take a look at those lug holes on a microscopic level, you will see tiny scratches that are caused every time you lift it up. 2 - Screw Removal (Your Fault): You don't know how to drive a screw with a screwdriver properly. You angle it like crazy and don't hold the watch case properly while doing that. This causes the screw hole to get a tiny bit bigger in the long run. If you take a look inside the screw, you'll see there are so many scratch paths due to the wrong angle handling. So, try to keep it steady at 90 degrees and don't angle it. Sometimes you may have seen when you remove a screw from a plastic material, the screw threads come out with a little bit of plastic of the material. In that case, don't mix the screws even though they are the same screws. In this case, it doesn't really matter due to the Casio carbon core case. 3 - Don't Leave Your Fingerprints (Your Fault): Once you remove the case back, don't touch the other side of the metal as it has gasket grease on it. Look at the case now; grease is on the watch case everywhere. 4 - Insulating Rubber Pad Removal (Your Fault): The way you lift that insulating rubber pad on the circuit board is also wrong; you forced from one side and angled to lift the whole thing up. 5 - Metallic Battery Holder Plate Removal (Casio's Fault): They should have done a great engineering job to make it more user-friendly for the battery removal process. That watch doesn't deserve to get poked by tweezers to remove that metallic holder plate. I like the closing mechanism where you have to push it down to lock the battery in place, but I don't like the way it needs to be unlocked. They should have one pressure point to unlock it easily when pushed. It must be engineered and designed carefully so the battery doesn't get removed when the watch falls and the shock goes through them.
After changing the batteries and reassembling the watch I noticed a thin circular plastic ring that looks like a washer, whitish in color, about the same diameter as the battery, on the table where I did the procedure. Did this come from the inside of the watch?
Yes, the watch has been working fine, but I saved the little plastic washer pending finding out if was actually in the watch. I thought perhaps it might have been packed with the new batteries that I put into the watch, since it is approximately the same diameter as the battery.

Never heard of this channel, but you talked me through changing the battery which was more complicated than I had imagined!

Thanks, man. I would have lost it on the AC to - part.
You are welcome! Enjoy your watch! 🤩
Thank you 🙏 is it still water proof?
Yes, if the gasket was placed the right way, the screws all the way down, everything should be fine.
@@vintageradar thank you so much man💪🏼
My pleasure! Enjoy your watch@@Rally_0492
how does the watch know what day of the week it is
Great video! Do you have any recommendations on what type of grease to use if the gasket needed some care?

Well, thanks watch-master. Deserved criticism I guess.

What model do you have? Some might have an extra gasket, but as you can see for this one it did not appear.
GA-2100

how long does the first battery last? typically? i don't use the light
They say 3 years but usually it lasts longer on G-Shocks.
@@vintageradar what have you personally seen lasting? or heard?
Mine lasted around a year only.@@mooooooooooomooooooooooomo6829
