Before you answer, please, take a look at these pictures.

I recently replaced the battery on my S6 Apple Watch LTE following one of the repair guides here.

Everything ok, the watch is working fine.

However! Upon reassembly, I found that brownish/reddish film both on the case, and on the display. On the display side, it was already partially unglued.

So I thought: ook, maybe it's just another adhesive strip I need to peel off... Which I did. I removed both strips from the case and from the display. And replaced everything with only one adhesive strip, the one that came with the battery replacement kit.

Something like this.

So, it was a seal on the display with a brownish/reddish film on top of it, an identical one on the case (you can see it in the picture above), and some glue (the transparent one you can see in the pictures) in between them. Well, it was the same glue on all of them, but yeah.
So:
Seal on the display
Seal on the case
Glue in between the two
And glue under each brown strip.

Now, aside from the fact that the display didn't stick and constantly pops up of the frame, when putting back everything, I noticed the display was sitting a tiny little bit under the edge of the frame. It made kind of a lip of some sort. It's not noticeable unless you look really close, or if you run your finger over it.

Other than that, everything works fine, as far as I can tell.

However, now I wonder:

1. 1. should I have removed those strips (they felt a bit harder to remove, but I just thought it's probably just a harder glue to remove)?
   
   Funny enough, before removing those strips, I asked Google about it, and the first answer was: don't remove it, that's a 3D Touch Sensor. And I was like: what 3D Touch Sensor? Series 6 doesn't have that! And of course, it said: you're right, my bad. So I removed it, and now I'm confused.
2. 2. is there a 3D Touch/Force Touch sensor on the Series 6?! Cause, as far as I know, there isn't!
   
3. And if so, then what the hell are these sellers sell on sites like AliExpress (here), as "3D Force Touch Sensor Gasket For Apple Watch Series 1 2 3 4 5 6 7 SE Gravity Induction Sense Coil Flex Cable 38mm 40mm 42mm 44mm"?
   
4. For Series 1-5, yes, there is a 3D Touch sensor. But with Series 6, as far as I know, there is no such thing. So...what the hell is that?! A wireless sensor? There is no connection to the motherboard! How would that even work? Is it just a simple waterproof gasket....?
   The replacement they're selling seems to be similar to the thing I removed. So I'm thinking it's probably a multi-layer kind of sealant (is it?).

1. 3. do I need that? If so, is that supposed to replace the regular adhesive strip? Do I need to add both? I'm so confused!

What's even more confusing is that the guide I followed didn't seem to have any of that neither on the display side, nor the case side. So I thought: ok, he might have removed it. So here I am, removing it as well and cleaning everything up so that the new seal can properly adhere to the watch.

Can anyone, please, tell me what the hell is going on? Cause I'm completely lost at this point.

EDIT:
Apparently, there are different kinds of adhesive strips. And yes, as far as I can tell from this video here, that is supposed to be a lot thicker than what I got.

EDIT2:

The reason why the display would lift up is because this kind of adhesive strips (both the one that came with the battery, and the double sided one) are meant to be applied with a bit of heat and a bit of pressure. After heating up the watch with a hair dryer for a couple of minutes, and letting it clamped down for a few hours, looks like the issue was fixed.

So yeah, if you only apply the adhesive strip, without heating and keeping the watch pressed down for a while, it will likely not stick properly. I wouldn't be courageous enough to take this to the pool or anything. But at least it doesn't lift up on its own anymore.

I bought Apple Watch (45 mm) Series 7 screen adhesive. After an extremely thorough cleaning of the metal frame and the screen borders where the factory glue was applied, the adhesive appeared to fit perfectly. I clamped the screen and frame with four clamps for 48 hours, and it seemed fully bonded. However, after about two weeks, the bond started failing on one side and eventually the adhesive let go on roughly half the screen.

I removed the failed adhesive and reattached the display using a black gel adhesive commonly used for phone screen replacements. It has held securely for about one month and two weeks so far.

The adhesive I received was branded Tesa. I chose it thinking it would be a cleaner option, but in the end I had to switch to the messier gel method. I originally selected it because I was also replacing the Series 7 battery, and the battery replacement works great. The screen adhesive, though, did not.

I have a Casio A168WE watch that I really love, but I keep running into the same issue: after a few months of use, the metal strap clasp doesn’t close properly anymore. It seems to loosen over time and eventually won’t hold securely, which makes wearing the watch risky.

I’ve even bought several identical models to compare, but the same problem happens every time.

I’d like to know:

• Can I repair the clasp (tighten it, replace a part, adjust it)?
• Or do I need to replace the entire strap?
• Is there a long-term fix to stop this from happening again?

Thanks in advance for your advice

Has anyone successfully opened this watch and replaced the battery? If so, what tools are required, and are there any specific pitfalls (like hidden cables or fragile sensors) I should be aware of? Any advice or photos of the internals would be greatly appreciated!

I ended up buying a charger clip and promised myself to post the pinout to help anyone who needs to charge it without the clip.
