I've had my Apple Watch (42mm) for a month now. I've been slowly raising my daily move calorie goal each week. Suddenly yesterday my watch started giving me move calories without any work. Today same thing. During a 3-hour car ride where I didn't move at all, the watch said I'd burned lots of calories - later I even laid it on the couch for a while and the calories still increased by one, all by itself! Something is definitely off... The only thing I can think of is that I rode on a 4-wheeler a bit yesterday, not very fast and not for a long time (15 mins). But can't see how that would suddenly make the watch start over-counting move calories? Surely the watch should be able to withstand that? I have restarted the watch and the Activity app, but it's still 'giving' calories without any work (while seated, etc.). Before yesterday, I definitely had to earn those move calories, so I'm baffled at this new problem. Any ideas how to go about troubleshooting this? Anyone else experiencing similar issues?
