Great watch. The watch and app are great for tracking activities - for hikes it shows elevation, distance, calories, route. For pool swimming, it detects my stroke and times each lap. The sleep metrics seem comprehensive. The watch also has a nice look to it. I probably only use half the functions. The only downside is the battery life, depending upon how active you are. I don't mind charging it for 1 - 1.5 hours per day to keep it going. I chose the 47 mm size as I am a male with a XL size wrist. 47 mm seems a reasonable size that should be okay for most.
A little higher than usual on price but I've always had a good experience with Samsung products. Watch does well and the upgraded features is a nice touch. Battery life can always be better but they are improving.
I like this watch better than the 5 pro it replaced but I still have gaps in my sleep record that I didn't get with my older (non Samsung) watch. I also couldn't adjust the band it came with to fit my wrist and since it uses a different method to attach the band I had to purchase a few aftermarket bands to get one that fit snugly.
The Galaxy Watch Ultra is an excellent watch, and I'm very pleased with the design and functionality. There's only one feature I wish it had - rotating bezel. I didnt deduct on my rating for that, because i knew before purchasing.
The digital version of rotating bezel works well enough, but it is more satisfying (and accurate) with a physical rotating bezel (complete with click-click-click). Maybe on the next flagship watch we'll get that feature back.
