The watch Nico posted, the VC, is better looking than I would have thought, as my feeling about Vacherons is akin to some others- a bit bland, or pedestrian these days. Nothing in their present catalog really moves me (except maybe this PCC). Lange has, for many years now, been my favorite watchmaker. I've evened argued that this brand has surpassed Patek in quality and versatility. But I'm not sure I would choose this option over the 5970. There is something to be said for the pure, iconic status/look of Patek Philippe when it comes to this combination of complications. And quality is, of course, of no concern. Everything I've ever read about the 1518, 2499 and 5970 has been (superlatively) positive.
Well, there is plenty of time to look over all these watches as I am quite new to this stratus. Great choices, and, apparently, plenty to choose from. Thanks for allowing me entree into this Forum with so many thoughtful responses to my original question.
