Pairing issues after screen replacement

Pairing issues after screen replacement

Hey guys, I'm unable to pair Apple Watch 3 GPS only version with any iphone. I tried to reboot iphone, delete network settings, try another phone, reboot watches. I've replaced the screen on the watches, they’re 1OO% unpaired and deleted from icloud. Phone starts pairing the watches but when it comes to activating the watches the iphone will stop the pairing and starts canceling the pairing process. Any recommendations?
