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.
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.

Well, thanks watch-master. Deserved criticism I guess.
Great video!
🙏 Thank you!
Great video, thank you so much!
You are welcome! Enjoy your watch!😎
Thanks, man. I would have lost it on the AC to - part.
You are welcome! Enjoy your watch! 🤩
Nice video.
You are welcome! Enjoy your watch!😍
Great video! Do you have any recommendations on what type of grease to use if the gasket needed some care?
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.
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
