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.

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
Thank you kindly! I followed along and all went well. I would have been lost on the hand alignment without your amazing video.
You are welcome! Enjoy your watch!😍 See you in the next video!
Never heard of this channel, but you talked me through changing the battery which was more complicated than I had imagined!

thank you! (FYI, for getting back to 0:00/SUB mode press ADJUST button for 6 Sec)
You are welcome! We have tutorials for hand adjustments, etc as well.
Great video! Do you have any recommendations on what type of grease to use if the gasket needed some care?

my watch has a foggy screen after battery replacement. how do I sort this?
Does it affect water resistance?
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
@@mooooooooooomooooooooooomo6829 Mine lasted 3 years, 4 months and 22 days, same model with the video
I bought this exact watch in early 2020 and the just died this morning, so nearly 4 years from the stock batteries.
Muchas gracias, me ha sido de gran ayuda.

Well, thanks watch-master. Deserved criticism I guess.
Great video!

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

Thanks, man. I would have lost it on the AC to - part.
You are welcome! Enjoy your watch! 🤩
Thanks so much, this is exactly what i needed!!
You are welcome!😎 Enjoy your watch and hope to see you around on the channel. Have a great day!🤗
how does the watch know what day of the week it is
They have introduced all the years inside the watch's memory.
Thank you🤙
You are welcome! Did you manage to replace the battery by yourself?
Great video, thank you so much!
You are welcome! Enjoy your watch!😎
Nice video.
You are welcome! Enjoy your watch!😍
What is the battery code number used?
2 SR726W Batteries: amzn.to/42rkiXV
Why do you have to reset the watch? Can't I just put in new batteries and be on with my day?
That is what G shock recommends in order to eliminate all possible errors.
Bought july 2021... Battery just died... August 9,2024
I thought it would last for 10 yrs😂
Not on this one. You have the ones with 10 year battery.
