Made for the Only Watch 2013 charity auction, this Piaget watch shattered another record for thinness, a skill for which this brand is well-known. The watch contains in-house Caliber 1200S, the world’s thinnest automatic openworked movement (2.40 mm thick). In this unique piece, Piaget has treated both the movement and the 18k white-gold case with a black PVD finish. The watch, with a case measuring only 5.34 mm thick, is the most slender in the world equipped with an automatic skeletonized movement.
Roger Dubuis introduced a watch combining a skeletonized movement with a flying tourbillon. The Roger Dubuis Excalibur 42 Skeleton Tourbillon, which houses a skeleton tourbillon, features 165 components and is powered by the RD505SQ caliber. The white gold version (seen here) retReails for $164,500, while the rose gold version retails for $153,500.
