The Roger Dubuis Excalibur Spider Skeleton Flying Tourbillon takes the openwork motif even farther, using skeletonization techniques not only for the movement — manual-wind Caliber RD505SQ — but also for the case, flange and hands. The “Spider” reference is to the complex, sculptural, spiderweb-like look of the movement, which also incorporates the familiar star shape. Another design motif of the Roger Dubuis Excalibur line is also present, namely the tourbillon carriage in the shape of a Celtic cross. The movement, made up of 165 parts and holding a power reserve of 60 hours, also boasts high-end finishes including a circular-grained plate and côtes de Genève decoration; it has also earned the Geneva Hallmark.The flying tourbillon, placed near the 7 o’clock position, makes one rotation per minute.
The titanium case is 45 mm in diameter and water-resistant to 50 meters. The black flange features a white transfer minute scale and Roger Dubuis logo; the gold hands are treated with black DLC. The watch comes on a black rubber strap with titanium folding clasp.
Prices start at 54,000 Swiss francs for the Roger Dubuis Excalibur Automatic Skeleton and 135,000 Swiss francs for the Excalibur Spider Flying Tourbillon.
