Roger Dubuis Excalibur Spider Skeleton Automatic

Synonymous with the contemporary outdoor, automobile-inspired vibe embodied in the Roger Dubuis ‘Technical Skeletons’, the Excalibur Spider Skeleton Automatic is a fresh blue/black/red expression of the talent and ingenuity deployed by the ‘pioneer of contemporary skeletons’, showcasing its ability to raise this workmanship to the rank of a contemporary art form.

Leveraging the expertise acquired over the years through its avant-garde movements revealing its own unique vision of this principle, the generous 45 mm titanium case is interpreted according to the Spider concept that extends skeletonisation beyond the movement to include the case, flange and hands.

Enhancing visibility and promoting transparency, this principle forms powerful architectural and sculptural effects that highlight the unique beauty of these sophisticated mechanisms. The original case construction and the use of ‘disruptive materials’ such as titanium also serve to ensure a super-light and pleasing feel on the wrist.
In this new Excalibur Spider Skeleton Automatic version, cool colour contrasts are the keynote, achieved by DLC treatment of the case, and crown, vulcanised rubber details on the bezel, crown and container, along with red accents provided by the ring, crown, hand tips and strap stitching.

The theme of contrasts is also expressed through finishing textures, notably including polished chamfers and satin-brushed sides. To ensure optimal readability by night and day, the applied screws on the flange as well as the tips of the hands sweeping across the dial are enhanced with Superluminova.

The multi-material strap with its black rubber base and blue calf leather inlay is secured by a DLC-treated titanium folding buckle. This ruggedly handsome model is driven by Calibre RD820SQ – which in 2015 became the first Roger Dubuis automatic skeleton movement.

It typifies all that is bold and beautiful about the in-house practice of open working the parts of the calibre before assembling them, rather than the common practice of skeleton working a pre-existent movement.

All faces of its 167 components are meticulously hand-crafted in accordance with the stringent quality criteria and prestigious finishing governing the “Poinçon de Genève” certification.

The design and height of the famous Roger Dubuis micro-rotor – a first in a skeletonised automatic Roger Dubuis movement – effectively enhance the spectacular 3D effect favoured by the Manufacture, as does the raised position of the signature Astral Skeleton decor.

It offers a fresh interpretation of the distinctive multi-layer approach to watchmaking. Typifying the blend of formal aesthetics and useful functionality adopted by the Maison, the instantly recognisable star shape features tips pointing to hour-markers, thereby enhancing both clarity and legibility.

Issued in an 88-piece limited edition, the Excalibur Spider Skeleton Automatic is a vibrant microcosm of the traditions, innovation and expertise cultivated and perpetually enriched by the specialist of technical and architectural mechanics.
