Question Best GPS+HR smartwatch?

[MowWow]

Hey everyone,

I'm struggling to choose my next smart watch, I'm counting on you to help me have more clarity.

Here are my needs:

- Accurate build-in GPS, I do a lot of running outdoor (not trail)

- I train a lot (fitness trainings, TRX, stuff like that), so I want a watch that has a good HR accuracy

That's it, I don't care about having cool features, or connectivity stuff, I don't care about paying with my watch or texting or receiving calls or anything like that. Just a good GPS, and a good HR accuracy.

My phone is a Samsung, so I can't buy an Apple watch.

My current watch is a Garmin Forerunner 935, and honestly I'm very disappointed. Not only the GPS doesn't seem to be accurate (I run with friends who have Apple Watches and other good Smartwatches, and I always have to run an extra 100 meters at the end to complete the 5K run lol).

The HR when training is way far from being accurate, sometimes it says that my heartrate is like 50 when in reality I'm like working hard in a training. I noticed that if my arms don't move, the HR is always low.

Budget is around 500$

Thanks for helping me with this!
