Rebuilding the 2000-year-old Antikythera as a watch

NVP3D: The oldest known mechanism to use clockwork gears, called the
Antikythera after the place it was discovered, was found in an ancient
Greek shipwreck more than a hundred years ago. The device, of which only
82 badly corroded fragments remain, not only predicted solar eclipses
but also organized the calendar in the four-year cycles of the Olympiad,
forerunner of the modern Olympic Games. The watchmaker Hublot has now
miniaturized the Antikythera from the size of a shoebox to something
that you can wear on your wrist. This version also tells the time.
