I am ever so slightly embarrassed, feeling a little foolish basically.
I have a Pebble classic (the original one). I stopped using it some time ago because the screen would end up corrupted after several hours of operation. I went out and bought a Garmin but still used the Pebble now and again (for a few hours at a time only).
Fast forward a few years: I decided to try a different watch face. It turns out that there's no problem with the Pebble hardware, only with that particular watch face I had been using! All these years, I've been missing out on using the Pebble.
So I'm back to using the Pebble full time. It's just so much nicer, not just the incredible variety of watch faces I can choose from but especially in terms of the consistency in the user interface compared with the Garmin. Makes me look forward even more to the delivery of the new Pebble Time 2! :-)
The Garmin is relegated to when I need/want the GPS facility.
