There's an Apple watch face called "solar dial" that's pretty similar, and I've seen others like this.
To me this is the most logical watch face — everything else just confuses matters.

Love your app btw, I made a similar clock years ago but with just sunrise and sunset times. I've just updated it with suncalc.js to add twilight times also, so thanks.
