New Roger Dubuis Excalibur Spider Limited Edition with White Rubber Strap

Roger Dubuis introduced its Excalibur Skeleton Flying Tourbillon — the technical chef d’oeuvre of its “Year of the Skeleton” — at SIHH 2015. This summer, the Swiss brand introduces a limited edition of the watch, available exclusively at its recently opened New York City boutique.

Roger Dubuis is well-regarded as a pioneer in skeletonized watch movements, opting to design them in an openworked style from the ground up, rather than employing the typical method, used by most brands, of skeletonizing an existing movement. It is also noted for the fact that all of its watch movements are stamped with the prestigious Poinçon de Genève (Hallmark of Geneva), a quality seal awarded by an independent bureau in Geneva that judges movements on 12 criteria.

The Roger Dubuis Excalibur Spider Skeleton Flying Tourbillon takes the openwork motif a few steps further than most watches in the collection, using skeletonization techniques not only on the movement — manual-wind Caliber RD505SQ — but also for the case, flange, and hands. The “Spider” reference is to the movement’s complex, sculptural, spiderweb-like architecture, which also incorporates the off-centered “star” motif that characterizes all Roger Dubuis skeleton calibers. 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 179 parts and holding a power reserve of 60 hours, earns its Geneva Hallmark with an array of high-end finishes, including a circular-grained plate and côtes de Genève decoration. 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 transfer minute scale and Roger Dubuis logo; the gold hands are treated with black DLC. The Excalibur Spider Skeleton Flying Tourbillon Americas edition, which is limited to just 20 pieces, comes on a white rubber strap with titanium folding clasp (the original model was on a black rubber strap), and also distinguishes itself from its predecessor with red and yellow accents on the dial and flange. The watch, available solely at the Roger Dubuis boutique on 545 Madison Avenue in New York, retails for $167,500.
