I've had a few over the years. The first was a Moto 360 2nd gen - I still have it but it doesn't run Wear OS very well anymore. I upgraded that to a Huawei GT2 watch, but the metal on the back began to react with my skin so I had to stop using it. I swapped it with a friend for a Fitbit Versa, and while it's really nice (and has killer battery life) it severely lacks in apps and capabilities that a regular Wear OS watch has, so I went back to the Moto for now.
I'm looking at upgrading it, but I'm having a very hard time finding a watch I like. So far, though, if rumors do hold, Samsung's next watches may be something I will have to look into, especially if the rumors of them going back to Wear OS from Tizen are true.
