Introdução
Use this guide to replace the Force Touch gasket in your Apple Watch Series 4.
In order to replace the Force Touch gasket we recommend to remove the display first. However if you’re feeling confident, it’s possible to remove the Force Touch gasket without removing the screen.
Make sure to update your Apple Watch to watchOS 5 or later (and the paired iPhone to iOS 12 or later) to avoid pairing issues after a display replacement.
Replacing the display can cause issues with Apple Pay. If possible, to reduce the likelihood of problems, delete all your Apple Pay account info before the replacement, and then re-enter it with the new display installed.
This guide shows the procedure on the standard, GPS-only version of the watch, but the cellular/LTE version is similar.

Before starting repairs, take your watch off the charger and power it down.

If your touchscreen is broken and prevents powering off the watch, use this alternate method to power it down.

Because the gap between the screen and watch body is so thin, a sharp blade is needed to separate the two. Read the following warnings carefully before proceeding.
-
-
-
Prepare an iOpener (or use a hair dryer or heat gun) and heat the face of the watch to loosen the display adhesive.
-
Leave the iOpener on the watch for at least two minutes to fully heat the screen and soften the adhesive holding it to the case.
-
-
-
Place the edge of a curved blade into the thin gap between the display and the outer case. Start at the short side of the display, closest to the digital crown.
-
Press firmly straight down into the gap.
-
Once inserted, tilt the blade to pry the display open slightly.
This part is REALLY hard! Even after using the iOpener to warm the watch I had to use A LOT of force to get the blade in between the glass and the case. Be very careful when prying the display. I applied way too much force and my blade shot into the case under the display. I don’t think I damaged anything, but I did replace the force touch gasket to be sure.
I have a stainless steel case, not sure if that makes a difference, and was unable to do this without breaking the screen. Be very careful. Followed instructions but could not get the screen to release no matter how hot I got the watch.
I am moderately experienced at opening Apple devices having replaced batteries in several iPhones, iPods, and an iPad. I could not get the watch open with the x-acto knife blade as shown. I found other sites showed using a 0.1mm thick tool. I bought one and found it relatively easy to open the watch. It has the advantage of going in horizontal rather than vertical so it went between the glass and the force sense gasket. Force sense gasket wasn't disturbed at all. iFixit should add this type of tool to their offering.

It's likely that the Force Touch sensor will stick to the display frame instead to the watch's body. In this case, insert an opening pick under the display and carefully separate the Force Touch gasket from the display.
-
Slide the pick around the display to separate the adhesive between the Force Touch gasket and the display.
This impossible for me. I just left the force touch gasket attached to the display side. I was able to bend the display back with the gasket still in place.
See first the instructions for replacing the force touch gasket to familiarize yourself with parts that need separating. These instructions will seem unclear if you don't know what the force touch gasket looks like.

-
Open the display at max. to an 45° angle, and use tweezers to peel off the adhesive between the display and the Force Touch gasket.
-
Thread the adhesive around and behind the display cables to get it off completely. Since the adhesive needs to be replaced anyway, you can cut it if that makes removal easier for you.
-
-
-
Carefully fold the screen to the back until you get enough space to pry out the battery.
-
Insert an opening pick between the battery and the Taptic Engine.
If you are just replacing the screen then there is no need to remove battery.
When removing the screen I tore the two outer cables attached to the lcd screen. What are their purpose? I read somewhere they are just some sort of shield. Will my watch function normally without them?
thanks

Remove the battery.
When installing the new battery be aware that the sidewall of the watch directly above the contacts and cover screw hole is magnetized. This was shock to me and a little frustrating. Every time I attempted to place the cover with a tweezers it was pulled toward the sidewall. I pushed the plate in place with a spudger, then attached the screw to the tip of the screwdriver. I was then able to insert the screw with minimal disturbance to cover plate.

Apply a little bit of high isopropyl alcohol (>99%) to a Q-tip and apply it to the black adhesive foil. Let it penetrate the adhesive for about two minutes.
-
Alternatively you can place an a heated iOpener on top of the screen to loosen the adhesive. Apply the iOpener at least for two minutes.
-
-
-
Use a pair of blunt nose tweezers to peel up the sides of the black foil which adheres the cable to the rear side of the screen.
Be very careful not to damage the copper-colored ribbon cables at either end of the display flex cable. I found it impossible to remove the black foil without tearing these ribbons, and as my repair was ultimately unsuccessful, I have no doubt that this mistake was the cause of my failure. I wish this step had emphasized how difficult removing the foil could be. If you make the same mistake as I did, it will require advanced soldering to replace the display flex cable. That's a bridge too far for me with a 5+ year old watch, so it's off to the trash bin for it. Shame...

I have an Apple Watch SE 40mm that had a very cracked screen after falling on a tiled floor. Gift from my daughters for father's day, ouch!
Reputable service wanted 140.00 to replace the screen. I got cheap and got a kit on Amazon that had a screen with digitizer. Looked at videos on Apple Watch SE screen replacements on YouTube. Some great, & some bad. Watched over and over again the good ones.
Was able to get the screen off using heat gun. Released the latches and gently removed the three ribbon cables. Removed the adhesive strip that was kind of clear in appearance. Saw a light brown strip in the channel around the base of the watch. Thought it was part of the adhesive and pulled it out. Then I thought, sh*^t, was that the Force Touch Gasket! To make matters even worse the two ribbon cables on each side tore. I think they insulate the signals?? Looks like my beloved SE is toast thanks to me being a bone head! Should have sent it in for 140.00!
Do I need to replace the Force Touch gasket even though it isn‘t used anymore sine WatchOS 7?
I mean while replacing a display glass do I need to keep the Force Touch intact?
Yes because you need to glue and fix the Display. It’s also for the water resistants. :)
Is the adhesive supplied with a new Force Touch gasket to be used for subsequent screen removal and replacement? It appears the new Force Touch gasket has some adhesive after removal of the protective foil, is this correct?
Production of the force touch gasket varies (sometimes with sometimes without adhesive). So if it should not come with adhesive, use the separate adhesive to close the watch. And yes, when already equipped with adhesive the extra can be used for subsequent openings.
There is no mention of the adhesive, but the kit comes with 2 adhesive sheets.
How are those installed? One on the glass and one on the watch frame? Sandwiching the Force Touch sensor? Any considerations or tips?
What does the LCD adhere to? Does it adhere to the rim of the frame, or to the force touch sensor?
I would criticize this guide for one thing only, and that is the suggestion to remove the screen in the first place. The gasket and adhesive both can be fitted around the screen, and I found out the hard way that the ribbon connectors will NOT go back in their place easily, in fact, all I did was to push the connectors back in their place and try to push the plastic bar down, and the plastic broke before even light pressure. DO NOT remove the ZIF connectors, it is unnecessary and very risky.
Hi. I changed the screen on an apple watch series 4, now the screen works, whcih is great, but when I charge it, the green snake comes on but never charges. It heats up the bottom, gets very warm. Could it be the battery itself? Maybe needs a new one? Is rthere anything else that woudl be causing the battery to not charge and or heat up on the bottom when chaging the screen?
