And a good article on Hodinkee today: http://www.hodinkee.com/blog/hands-on-with-the-new-omega-speedmaster-co-axial-1957-live-pics-pricing-specs
I have to say, this is one hell of a good looking Omega. Only 41.5mm as well with the Cal. 9300 movement. I am glad to see that they can fit the 9300 movement into a much smaller package.
The purists will probably not like the date function but I must admit I did a double take when I saw the images in this article. Still, $30,000 for the yellow and rose gold versions means they'll be competing in tough territory, IMHO.
