I just pulled my Bangle.js 2 back out to play with making a better reminder system for myself. It works better than any of the other open source watches I’ve had with my GrapheneOS phone. The hardware isn’t open source as far as I know, but their mobile app (fork of gadget bridge) is, as are all the apps that run on the watch, and (I think?) the watch OS.
