The Zenith Chronomaster for $10k.

Or if your budget isn't quite up to the Zenith, this Baume et Mercier is pretty awesome, even if it's at the low end (i.e., $2400) and doesn't have a skeleton face.

But if you really want to go crazy, the 2010 Special Edition Panerai (with the full skeleton face) will do nicely for $160k.
