US Retail for the two on the strap is $19.8K. On the bracelet is ~30ishK. I saw them at a trunk show that my local dealer had for UN this weekend. They had both the dial variations, and I have to say that while I liked the black/blue dial, the silver one really stood out for me. I liked the watch more than the Anniv. 160 that they had there (sorry Bernard!) because while it was a beautiful watch, and the movement is truly something special, I really did not like the blue dial. If it was made with a silver dial, that would have pushed it over the top.
I am seriously thinking about the silver dial MP 950 as my first UN watch. I like the fact that it comes with a palladium deployment, not just a buckle.
