A Pebble can go on for a week (longer without smart features enabled). My smartwatch, Fossil Hybrid HR, works for 2 weeks with smart features enabled. They go automatically off with < 10% battery, after which the watch still functions (I would prefer the option to put the smart features off, as well as bluetooth).
I'm in the market for a new watch as I just ditched the Apple Watch after moving back to Android (LinageOS). Not wanting to be locked in yet again to a watch/phone platform, but not knowing how long before PineWatches were back in stock, I didn't know what to look out for.
Missing my Pebbles, this looks like an awesome replacement. Thanks for the link!
I got one of those in between. Extremely limited smartwatch capabilities, and I can't put Bluetooth off. Plus without physical buttons. I want physical buttons during commute/travel.
