I just got an Apple watch S3, Nike and have had disturbing heart rate results. The first was 153 while sleeping (once, most are an average of 59) Then at the gym, on the treadmill, the treadmill reported 117 and the watch said 182.
Yesterday I was driving, not at all agitated and it said 203!. I was not anywhere near an elevated heart rate at that time.

Hello,
For best results
Start with a good fit. Even under ideal conditions, Apple Watch may not be able to get a reliable heart rate reading every time for everybody. And for a small percentage of users, various factors may make it impossible to get any heart rate reading at all. But there are things you can do to help Apple Watch get the most consistent and best heart rate readings possible. Learn what else affects your reading.
