  • Great watch!
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
Great watch! Super easy to use, perfect functions for what I wanted, and thus far very durable!

  • My second Garmin
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
Serious into running? This watch has all the analytics you need to run your best race! GPS is super accurate, while other sensors make you aware of the intensity and effort you are putting out. Suggested workouts and top notch sleep tracking. This watch is a must have

  • So happy my Fitbit died.
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
After running a 10K in the rain my Fitbit finally died. After researching a replacement I ended up on this watch. I couldn’t be happier. I appreciate the upgrade from the Fitbit. I love the gps as well as adding races to a calendar. Of course the big selling point was being able to handle water. I also enjoy the morning report. ... show more

  • Sleep measurement not accurate
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
First, the only gripe that I have. When I get a crappy sleep, it says so. When I have a good sleep it states that it was poor. What I like: more features that I’ll need in 2 lifetimes. All sorts of exercise routines-for the data wonk, you can input specific runs. Screen is superb- I came from a 45- it’s like going from ICE to a Tesla. Battery is adequate- I use it with gps & frequent O2 sat, easily get 2 days. The accuracy & gps acquisition is fine. If sleep measurement is important, I’d look elsewhere. If it’s not, I’d give it 5 stars. ... show more

  • Love this watch
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
This watch has new features my old Garmin 935 didn't have, like tracking your overall energy levels with a body battery meter. I also think the heart rate monitor is more accurate with four sensor points instead of one. Garmin continues to knock it out of the park with these watches! Battery life is great at over two weeks. ... show more

  • Long battery life.
Color: Tidal Blue Size: 46 MM Style: Non-Music Pattern Name: Smartwatch
I love all the features this watch has to offer but my favorite is the long battery life. I will go days without charging it. I am a runner and my long distance runs, I am not nervous that it will die.
