I have both a Pebble Time Round (dead now) and a standard Pebble Time.
I run them both through gadgetbtidge with custom firmware (you have to use rebble firmware anyway), so the watch has NO internet access, meaning no spying.
Overall though, as cool as it is, smartwatches are still largely pointless devices. The main benefit they offer is slightly more convenient time and notifications, but even then, getting your phone out is easy.
Still, I dig the nice displays on both of the ones I had.
