Over the last few weeks my heart rate although its recording its not correct. For example did a spin class tonight and had a heart rate high of 116, this is not the first time its been incorrect, when checking my heart rate manually its was between 150 - 170. The watch is approximately 8 months old. I wear the watch in the position its recommended and have also cleaned the sensors without success, consequently its not worth wearing as its so incorrect. Can you please advise how I can get this issue resolved?

Eddie
