cool, seems like the ideal device for something like Circa Solar as watch face https://www.circa.bio/ Although as far as I can tell, Circa Solar isn't open source. But maybe there's another similar thing that is? I always liked the idea of an "apparent solar time" watch face, and never did find a way to do that with Apple Watch.
