Garmin Fenix! The new ones are very expensive ($1000), but I picked up a used Fenix 5X a few years ago when it was the most recent model for $350 and I love it! Battery charge lasts about 3 weeks on mine and 6 weeks on the newest ones. It has sports tracking activities for just about anything you'd ever do, a great phone app interface, doesn't need to be charged for weeks at a time, and has GPS topo maps that you can use while backpacking, cycling , jogging, or even driving. I was able to track how far I paddled in my kayak thanks to the GPS. Anyways, it's a great watch if you're looking for a fitness tracker as well as a smart watch to give you phone notifications, music controls, and that sort of thing. The only drawback is that the screen resolution isn't great on the older ones since they use eInk screens instead of fancy screens. The new one uses OLED, so it's supposed to look better. Oh, and they're not touch screens. That was a little clunky for me when I first got it, but it doesn't bother me now.
