. . . is overshadowed by the Skeleton, which is one of very few to compete with my affection for what I consider to be the most compelling design of all, namely, the Omega central tourbillon. The Skeleton strikes me as a counterpoint to the Omega in aesthetic terms, with a focus on rational design derived from empirical observation accentuated by the revelation of skeletonization, as opposed to the ethereal appearance of the Omega with it's symbolically laden construction, mimicking a cosmological 'music of the spheres' with it's centrally located tourbillon and enhanced by the seemingly floating sapphire hands. One represents reason, the other, faith . . . both powerful statements of design. Here are a few photos, courtesy JLC BH:

The decision to skeletonize the movement without adding decoration strikes me as an inspired move, as the aesthetic effect is curiously enhanced . . . I found myself wondering had Da Vinci designed a wristwatch, would this be the direction he would've taken? The absence of script is another inspired touch, in my opinion, as it lends an air of authority by it's silence.
