Apple Watch Not pairing

[Khan Mohammed]

My Apple Watch series 4 used for couple of months after screen replacement but it was very slow booting I erased all data on Watch & unpair from my iPhone
Then while pairing to iPhone it was unpairing automatically
I don’t know what cause it happening

Was this repair done by Apple? If so, contact them about your problem. If it wasn’t done by Apple, I suspect whoever replaced the screen either damaged your watch or used parts / process that may trigger the watch not being a compatible device.

I concur with @BasicGreatGuy : it sounds at first blush that the repair did a number on the watch that’s now preventing it from pairing.

It was replaced by third party
I think he had changed screen without turn off Watch
After he replaced it stuck on apple logo for 1 hour
Several hard reset attempts it was booted
I used for few months then erased my watch & unpair from my iPhone
Then after got this issue
