During the 15 years+ that I'm interested in watches, I have learned that it is better to get the piece you realy want (and wait for it to happen as financials are always limited
), then always buying new watches you just like. At the end you spend the same amount all together than for the one watch you want. Why do I say this... Some weeks ago, I tried the Zeitwerk WG with black dial a I'm loving it, I want it. Even enough at this price point to take the plunge probably still this year. But, and a big but, then you have this watch (which I never saw in reality though) that I realy adore, I even want more.
But like Francois Xavier said, it is platinum and that equals a super premium at Lange. I must admit that is normaly out of my price range, I (we the family) still have a lot of other hobies 
What should I do: Zeitwerk WG with black dial or wait a few years to get a second hand Zeitwerk "phantom"?
We'll continue the discussion in Paris on the 23th I suppose.
Great pictures btw!
