Cartier's watch is part of the 'Clash [Un]limited' collection, which is rooted in precision - its development required over 3,000 hours of study, followed by 880 hours of prototyping. Made from 18-karat yellow and violet gold - the latter made specifically for the Maison - it has a unique bracelet comprised of studs, rotating beads and clous carrés. The sapphire glass crystal is faceted 16 times for an angular, geometric look.
