This mostly just reminds me that I really miss my Pebble Time Round watch. Perfect form factor, great battery life.
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.
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.
