I can tell you from personal experience they will not repair Apple Watches - they recycle them and charge a pretty hefty replacement fee if you do not have AppleCare+. I had a Stainless Steel Apple Watch Series 6 just outside the 1 year warranty. The display came dis-attached from the frame, either because the adhesive failed, or the battery had swollen. Like, literally I was just driving down the road and the display started hanging off the watch from its flex. The Apple Store wanted $400 to replace it - would not even evaluate a repair.
