Seen these advertised lately, and while I've given up on collecting (yeah, that's why, not the 'price tag') - trying instead for a more "Zen" and less possessive approach to life, there's still something to be admired:
#1) Van Cleef & Arpels Midnight Planetarium Poetic Complication: https://www.youtube.com/watch?v=sw5S2-T-Ogk
and
#2) Jacob & Co Astronomia Sky Watch: https://www.2luxury2.com/captivating-watch-complications-jacob-co-astronomia-sky-with-celestial-display-in-three-dimensions/jacob-co-astronomia-sky-watch/

#3) Christiaan Van Der Klaauw Planetarium: https://www.youtube.com/watch?v=H_fuu8vMjgo
That's only the beginning, but it's enough. They are beautiful.
