I went in to the Apple Store with the swollen battery issue on my 1st Generation Apple Watch 7000 series, and it was shipped off to Apple's repair facility. When I received the Watch, to my surprise it was no longer a 1st Generation, but they replaced it entirely with a Series 1. I've owned and sent in Apple products for repairs for years going back to my iPhone 4, but I always received the same model of device back that I sent in repair, even if it was a replacement device. Suffice to say, I'm pleasantly surprised that I got a free upgrade from my single core 1st generation watch to the dual core series 1... something I thought Apple would never do. Has anyone else had this experience with their 1st generation Apple Watch repair?
