About 5 years ago I bought probably the last watch I'd ever need. It's a solar powered Casio with timezones, and the normal 'digital watch' accoutrements. The little energy-saving details are fantastic. It has analog hands with a small digital screen. Why waste energy on backlighting when you can use glow in the dark paint that charges with the same light as the energy source? Too dark or too still? Turn off the screen until you move the watch. There was a time when it was in a drawer for a couple months while I was traveling, and when I got it out and put it in the sun, it fired right back up, and adjusted the time itself. I've seen it drop into a low charge maybe twice. It feels like it's meant to last forever, and I believe it's probably some of the best 50 bucks I've ever spent.

I've used a Fitbit and a couple friends have Apple watches, but the entire concept of charging an always connected timepiece just makes no sense to me.

I think I have the same watch - a Casio WaveCeptor Tough Solar. It was a 21st birthday present. The complete lack of need to replace batteries is amazing. I have the titanium version, which is astonishingly lightweight. And it is indeed tough - I've gone travelling, swimming, diving with it and it's fully functional. The timezones feature is also extremely useful when travelling, being able to swap between home and local easily. My current apartment makes it difficult to pick up the time signal though.

However, I bought a Pebble a few years ago, and I have to say there is definitely a way to do smartwatches right. The idea of charging a watch regularly is annoying, I can't deny, but Pebble did something right when they prioritised battery life. I routinely get over a week of use out of the Pebble, and that's with an always-on LCD screen (contrary to popular belief, it's not a traditional e-ink display, but a 'memory LCD', which has a refresh rate fast enough to display animations), which for all the watch does is quite acceptable battery life. It can fully charge from USB in an hour. And the ability to have a watch face showing a large amount of information at once (just like the 'complications' on traditional watches) really helps - on the main one I use, I can see the local weather at a glance. Having certain notifications pushed from my phone is also useful. Although sometimes, I do find myself ensuring the watch is exposed to sunlight like my Casio, trying to charge it.

How did it adjust its own time? I'm guessing GPS receiver?

Casio have a brand called WaveCeptor that picks up radio time signals transmitted from around the world; GPS is an enormous power-suck (receiver and processing) so using it for time is impractical on a low-power device.
