CHRISTOPHE CLARET. AN UNUSUAL 18K WHITE GOLD AND TITANIUM LIMITED EDITION SEMI-SKELETONISED TOURBILLON WRISTWATCH

X-TREM-1 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. The manually wound movement contains 419 parts and has a power reserve of about 50 hours.

Limited to only 8 examples ever produced, the present lot offers a very exciting opportunity for collectors.
