Mille is very nice, but there are far more exotic as you know. Baumgartner and the watches coming out of his partnership with Hysek is one thought. The Opus watches from HW... Opus V was designed by Baumgartner. The new Laboratory from Jaeger Lecoultre is the first mechanical that doesn't require lubrication... and then there are Oeschler's works for both the indi watchmakers and Nardin... the automaton, Freak, Freak Diamonsil, The famed Trio and many others. My most prized piece is a GP pocket repeater from 1865, all original, triple signed from Le Locle. So yes, it's all relative.
