I had original Pebble and even 7 day battery life was a bit annoying, couldn't imagine having to charge my watch every 2-3 days as some modern smartwatches have. Ended up getting just a solar powered casio with no smart features whatsoever...
Garmin makes ones with over 2 weeks of battery life but for the money I can't excuse spending on a watch just to get some gadgets.
I had a earlier Pebble, which was neat, but it mostly just got used for cycling so I could see who was calling without pulling my phone out. It was an interesting proof of concept for the time.
When it died, I tried a couple of things for my "active watch" before settling on a first-gen Apple Watch. It turned out to be so dang USEFUL that I wore it more than I wore my real watches, a trend that continues to this day.
