More on the Antikythera watch

Back when there was still a BNB they were working on a wristwatch version of the Antikythera mechanism, a 1st Century BCE mechanical sky map.  Now that they're Manufacture Hublot, that project has been continued and Hublot has shown off the prototype at the Musee des Arts et Metiers in Paris(Previously Mentioned).

The original is flattened, broken and corroded(left), so most of the understanding on the internals is based on CAT scans(right)

The watch movement is not yet finalized, but they've released a rendering (below) and over at thePurists Andrew (219) has some live pics of the protoype from the press reception last night.

I don't usually bother with the full movement specs, but these are not the usual "gear, screw and jewel count":
