My guess is that is a custom made dial, hands, bezel, and dome crystal. More complicated case work and one off custom parts would definitely drive up costs. The project x is only slightly modified using most of the original parts. It would only make sense that these would most likely cost more and if you really study them they should.
If I ever buy another modern watch, I will seriously consider this. I keep coming back to marvel at the pictures. It truly is a work of art.
