I'm looking for a watch which can track my calories spent daily, including resting/at a desk, as well as what I do with my time. I'd like a watch that tracks things like duration, with a readable display and can go from running to the weight room, to the pool seamlessly if I feel like it/sometimes up to high mtn summits(I have a gear s2 currently, don't take this to the mountains). I don't plan on having a bike power meter anymore so these features would be wasted. I dislike touch screens to a degree and consider an interval timer as essential, a built in heart rate monitor would also be essential.

Does anyone have a great recommendation for me? Thanks in advance!
