    Christophe Claret X-TREM-1 Watch

    X-TREM-1, the first of a new generation of timepieces, represents a major technical and aesthetic accomplishment: a flying tourbillon inclined at a 30° angle, mounted on a three-dimensional curvex titanium mainplate, equipped with a retrograde hours and minutes display system that is radically different from existing watchmaking conventions. Two tiny hollowed steel spheres, isolated within sapphire tubes on the left and right sides of the caseband magically move with no mechanical connection thanks to magnetic fields.
