I also had the problem, that my Apple Watch did not pair, after replacing the screen. But it was very strange, since the watch did pair at first. Then I was not able to add my credit card via Apple Pay or update to wOS 5.2.1 (from 5.2) and so I unpaired the watch, hoping that it would work once pairing it again. Unfortunately it would not pair again at all. So I opened it after reading this thread and figured out, that the GPS modules connector was loose and just fell of the display, when I touched the cable. So connecting the (not working) display from another watch made it pair and upgrade again but still I am not able to add Apple Pay. I guess that it recognises the GPS module and since it is wOS 5 it works even though it is not the original GPS module. But I think, because it is not properly connected to all three cables of the display the GPS maybe is not able to fix a location which disables the Apple Pay function out of security or licensing reasons.

I figured out, why the Apple Watch did not pair even though wOS 5 was installed.

Now I think this experiment confirms, that any display will work under wOS 5.2 (maybe even wOS 5), even if it is the display from another Apple Watch.

I have an Apple Watch series 2 with wOS 5.2 and an iPhone 8 with iOS 12.3.1

After installing a new aftermarket display I’ve connected the watch with my phone with out any trouble. But I was not able to update to wOS 5.2.1 Also I added my credit card to wallet on the phone after the repair job, but was not able to add it to the watch.

So I tried to completely reset the watch and try it all again but now I am not able to connect it to my iPhone at all.

I have another Apple Watch 2 that has wOS 5.2.1 and a weak battery and a Digital Crown with ghosting behaviour but still the original display. Might it work to install the original display on the other watch to resolve the connection problems?

Has anybody made similar experiences and any idea/advice what I might do?
