Wristwatch collectors out there?

[Footbag]

Seems like a good place to post this... I've got the bug for a celestial calendar watch. Something with a true celestial complication, i.e. moving Milky Way. I'm a big fan of Patek, but this one is a little bit out of my price range. Looking for something similar, but would like to save a few hundred thousand.

Has anyone come across any other brands making this complication?
