My Apple Watch is reading my heart rates too high

my Apple Watch is reading my heart rates too high!! I was out on an easy run and it was saying that it was at 197 bpm which is outrageous, because I have raced at 180 and 185. Also, the pacing was off. On my phone it was saying 9”05 and Whatch was saying 9”54? Should I trust the water or the phone and has the heart rate happened to anyone else?
