I have been getting a lot of erratic heartrate reads lately on my Series 0 apple watch, and my watch face is getting a bit beat up. I notice the back where the sensor is is also a bit beaten up. I got Applecare+ and am thinking about using it. I'm wondering if anyone has used it after the Series 1/2 launch, and if by any chance they got a nice surprise and happened to get a Series 1 back from Apple, since everything is the same except processor? I just am wondering if they are still stocking Series 0 for service purposes or if they are consolidating on Series 1. It doesn't matter in the end - I will need to use my applecare either way, but I'm a little curious as to what I might expect.
