"Why my Apple Watch S3 is not working, after replacement screen?" için yanıtThis is a bit of a dated reply but when I replaced a series 3 screen (see my ifixit repair guide) the display worked but I didn’t have touch and I couldn’t pair the watch. I re-opened the watch and reseated all of the ribbon cables. To my delight I was able to get touch and also pair the watch. The issue may be not having all of the ribbon cables seated properly.
