Roger Dubuis Excalibur MT

Overview

The Roger Dubuis Excalibur MT is an uncompromising expression of contemporary haute horlogerie. Its open-worked architecture places the mechanical drama at the centre of the watch, revealing the movement rather than concealing it beneath a conventional dial. At its heart is a flying monotourbillon, presented with the sculptural confidence and theatrical design language that define the Excalibur family.

This exceptional example is limited to number 44 of 88, making it a notably scarce collector’s watch as well as a highly distinctive piece for formal wear. Roger Dubuis’s Geneva-made skeleton calibres are central to the identity of the Excalibur collection: every bridge, wheel and finishing detail contributes to a composition that is both technically serious and visually expressive. Priced at £29,950, this watch offers an opportunity to acquire an unusual and technically ambitious Roger Dubuis at a level that reflects its rarity and character.

Within the wider market, the Excalibur MT occupies a compelling position between traditional Swiss watchmaking and avant-garde design. It has the presence expected of a luxury dress watch, yet its exposed movement and prominent tourbillon give it a far more dynamic personality than a restrained classic timepiece. For collectors seeking originality, hand finishing and limited production, this is one of the more individual choices in the category.

Brand and reference history

Roger Dubuis was established in Geneva with a clear ambition: to combine traditional Swiss mechanical watchmaking with a more expressive, contemporary visual identity. Rather than treating the movement as a hidden engine, the brand made it a defining part of the design. This philosophy became particularly visible in the Excalibur collection, where strong case forms, skeletonised calibres and tourbillon constructions created an instantly recognisable alternative to more conservative high complications.

The Excalibur name is associated with some of Roger Dubuis’s most technically ambitious and visually arresting watches. Its design language is built around bold geometry, open-worked movements and a sense of mechanical theatre. The collection has developed over time, but its central idea remains consistent: horological complexity should be visible, engaging and worn with confidence.

This Excalibur MT belongs to the limited production tradition that gives the manufacture’s more complicated watches their particular appeal. Number 44 of 88, it represents a tightly restricted series rather than a mass-produced luxury reference. Limited availability is important here, but so is the character of the watch itself. The combination of a flying monotourbillon, hand-finished skeleton construction and assertive Excalibur styling creates a product that is immediately identifiable without relying on conventional decoration alone.

For buyers interested in the broader category, this watch also demonstrates why the finest dress & classic watches can extend well beyond understated three-hand designs. A dress watch may be elegant, but it can also be technically adventurous, sculptural and deliberately unconventional.

Dial, hands and design detail

Strictly speaking, the Excalibur MT does not present a conventional dial in the usual sense. Instead, the front of the watch is dominated by an open-worked mechanical composition, allowing the wearer to see through the watch and into its architecture. This skeletonised presentation gives the piece its visual depth: bridges, wheels and the tourbillon cage become the principal design elements, while the absence of a solid dial keeps the construction exposed.

The flying monotourbillon is the natural focal point. With its supporting structure deliberately minimised on the visible side, the tourbillon appears to float within the movement, producing a strong sense of motion and lightness. Its rotating cage is not merely a technical device; it is a constantly moving display of the watchmaker’s craft. As the watch is worn, the tourbillon adds life to an otherwise static object, turning the passing seconds into a visible performance.

Hand finishing is essential to the appeal of a skeleton watch, because every surface is exposed to scrutiny. The existing description of this example emphasises that each component is finished by hand, reflecting the work of highly skilled craftsmen in Geneva. Such finishing is not simply decorative. It defines the edges, creates contrast between polished and brushed surfaces, and helps the complex architecture remain legible despite the density of the mechanism.

The overall design is expressive without being random. The bridges and structural elements form a deliberate composition, balancing open spaces with strong lines and carefully placed mechanical components. This is a watch for someone who appreciates the visual language of high horology: the interest lies not only in reading the time, but in examining how the movement has been conceived, assembled and finished.

Case, bracelet and wearability

The Excalibur case is designed to make a statement. Its presence is architectural, with a bold silhouette that frames the skeletonised movement and gives the watch an unmistakable identity on the wrist. Rather than following the discreet proportions of a traditional dress watch, it uses stronger forms and a more assertive profile to support the complexity within.

The case also performs an important practical role. A highly open-worked movement requires protection, while the front of the watch must remain clear enough to appreciate the construction. The Excalibur’s design creates a considered boundary around the mechanism, allowing the flying monotourbillon and hand-finished components to remain the focus. The result is a case that feels purposeful rather than ornamental.

The bracelet or strap configuration should be assessed alongside the individual watch, as the condition, fit and finishing of these elements can have a significant effect on how the piece feels in use. Whatever its exact configuration, the watch is intended to sit as a complete object: the case, attachment points and wearing surface work together to support its sculptural character. A watch of this complexity benefits from a secure, correctly adjusted fit, particularly when the tourbillon and open-worked movement are being worn as the centre of attention.

Although it is categorised as a dress and classic watch, this Roger Dubuis is not limited to the most conservative formal wardrobe. It can complement tailoring, evening attire and elevated business dress, while its modern geometry also allows it to work with a more contemporary style. Its versatility comes from its confidence rather than its neutrality.

Movement and technical specification

The defining mechanical feature is the flying monotourbillon. A tourbillon is designed to place the regulating organ and escapement within a rotating cage, while the flying construction reduces the visible support on one side. This creates the impression that the cage is suspended within the movement. On the wrist, the result is both technically fascinating and immediately recognisable.

Roger Dubuis’s skeleton calibres are manufactured in Geneva and form the mechanical heart of the Excalibur concept. The open-worked construction removes non-essential material to reveal the movement’s underlying structure, but that does not make the watch mechanically simple. On the contrary, skeletonisation demands careful planning, precise machining and a high level of hand finishing because the components are permanently on display.

Every component is described as being finished by hand, placing the craftsmanship of the watchmaker at the forefront. The visible bridges, edges and structural surfaces become part of the finished design, while the moving tourbillon provides a constantly changing point of focus. This is the kind of movement intended to be studied closely, whether under natural light or through a loupe.

Known information for this watch includes the Roger Dubuis manufacture, Excalibur MT designation, flying monotourbillon construction and limited edition number 44 of 88. The supplied details do not specify the case diameter, thickness, water-resistance rating, power reserve, calibre reference or exact case and bracelet materials, so these should be confirmed against the watch and its accompanying documentation before purchase. We do not substitute assumptions for verified technical data.

Sizing and how it wears

The visual impact of this watch is likely to be greater than that of a conventional dress watch because the Excalibur design uses strong lines and an open-worked display. Even without relying on exaggerated decoration, the skeleton movement fills the case with activity. It therefore wears as a focal point, drawing attention through movement, depth and finishing rather than through a simple polished dial.

Wrist comfort will depend on the confirmed case dimensions, the wearer’s wrist and the adjustment of the bracelet or strap. Prospective buyers who usually wear smaller, understated watches should be aware that the Excalibur MT has a deliberately assertive personality. Conversely, those who appreciate large-scale mechanical design will find that its bold profile is central to its appeal rather than an incidental feature.

For formal occasions, the watch provides a striking alternative to a conventional dress piece. The exposed tourbillon and skeletonised bridges introduce a sense of motion beneath evening lighting, while the case gives the watch enough presence to sit confidently alongside a tailored jacket. It is equally suited to collectors’ gatherings, where its technical detail can be appreciated at close range.

When evaluating the fit, attention should be paid to the curvature of the case, the security of the clasp or buckle and the adjustment available in the bracelet or strap. A complicated watch should feel stable and balanced, allowing the wearer to enjoy its movement without it shifting excessively on the wrist. Our team can provide further information on the physical configuration of this individual example.

Collectability and market value

The collectability of the Excalibur MT is supported by several distinct factors. It is a Roger Dubuis limited edition, restricted to 88 pieces, and this example is number 44. It also combines three features that carry strong interest among serious collectors: a manufacture skeleton calibre, a flying monotourbillon and extensive hand finishing. Together, these qualities place it firmly within the high-complication segment rather than the ordinary luxury watch market.

Limited edition numbers matter most when they are attached to a compelling design and credible technical content. In this case, the edition size reinforces the individuality of the watch without being the sole reason to consider it. The Excalibur identity, the Geneva-made movement and the visible work of the craftsmen give the watch substance beyond its production rarity.

At £29,950, the asking price should be considered in the context of its complication, scarcity and original manufacture. Buyers comparing values should look carefully at the condition of the case and movement, the presence of original accessories and documentation, service history, and the exact specification of the watch. These factors can materially influence the desirability of a high-value complicated timepiece.

The Roger Dubuis market rewards buyers who are comfortable choosing character over convention. The Excalibur MT is not intended to be anonymous or universally conservative; its value lies partly in its ability to offer an experience that few watches can replicate. For the collector who wants an expressive, technically serious and limited Geneva-made watch, this is an especially distinctive proposition.

Authenticity, condition and servicing

Authenticity is central when buying a complicated pre-owned watch. The movement, case, markings, finishing and accompanying materials should be assessed as a complete set, with particular attention paid to whether the visible architecture is consistent with the stated Roger Dubuis Excalibur MT specification. A skeletonised tourbillon movement offers many areas for inspection, and its exposed components make quality and originality especially important.

Condition should be judged carefully rather than reduced to a simple description. The case may show signs of previous polishing, the visible bridges may carry light handling marks, and the bracelet or strap can reveal how the watch has been worn. On a piece with extensive hand finishing, small differences in surface definition can be significant. We recommend that buyers request any available condition details and imagery relevant to this individual example.

Servicing is equally important. A flying monotourbillon and skeletonised calibre contain delicate, highly specialised components, so maintenance should be entrusted to an appropriately qualified specialist familiar with high-complication Swiss movements. Service intervals depend on use, lubrication, performance and the recommendations of the servicing workshop. A watch that has been correctly maintained is more reassuring to own and easier to preserve over the long term.

The supplied information does not confirm a current service date, warranty status, serial number or complete set of accessories. Those details should be verified directly before completing a purchase. We believe transparent information is essential, particularly when discussing a limited-edition watch at this level, and we will distinguish clearly between confirmed facts and details requiring further inspection.
