Approach S62 Issues

The step counter has stopped working, The Heart Monitor has stopped working. When playing a round of golf the distance calculator to measure my drives etc. has stopped working. The GPS is a little inconsistent. I have only had this watch for two months and all of a sudden these issues have cropped up. Extremely frustrating for what is a high end Golf watch. I have tried multiple hard and soft resets but nothing seems to work. Please help
