TAG Heuer has previewed an updated version of its iconic Monaco watch, the V4 Tourbillon, which can lay claim to being the world’s first belt-driven tourbillon. The amazing watch features a black titanium carbide case features a partially skeletonized dial that reveals the unique belt-driven movement that powers the watch. Completing the stealthy look is a beautiful hand-stitched black alligator leather strap with a black titanium carbide clasp.
