NF Roger Dubuis Excalibur Spider Carbon RDDBEX0508 Tourbillon Replica Watch

Excalibur Spider Carbon RDDBEX0508 – Dark Skeleton Drama on the Wrist

This NF Roger Dubuis Excalibur Spider Carbon RDDBEX0508 tourbillon replica brings the radical, openworked spirit of the original Excalibur Spider Carbon into an ultra-light, stealthy all-black package designed for everyday wear. [1]

New Factory (NF) has focused this V4 edition on real multi-layer carbon construction, an upgraded skeletonized movement architecture and a fully functional flying tourbillon placed at 7 o’clock, echoing the visual signature of the authentic reference. [1]

The result is a high-impact 1:1 homage that captures the visual language, wrist feel and bold presence of the original RDDBEX0508, while remaining clearly positioned as an independent replica piece with no official brand affiliation. [1]

Authentic Reference Context & Design DNA

The genuine Roger Dubuis Excalibur Spider Carbon RDDBEX0508 is part of the brand’s Excalibur Spider family, known for openworked cases, skeletonized movements and avant-garde use of materials such as carbon and titanium. [1]

On the authentic model, the case is executed in layered carbon with a notched Excalibur bezel, integrated skeleton lugs and a dramatic skeleton dial with the brand’s signature astral star bridge and a flying tourbillon dominating the lower left of the display. [1]

Typical specifications for this reference include a case diameter around 42 mm, a thickness just under 14 mm, a sapphire crystal front and back, and a manufacture hand-wound skeleton tourbillon calibre that emphasizes three-dimensional depth and architectural bridges. [1]

This NF homage respects that overall blueprint: a 42 mm multi-layer carbon case, notched carbon bezel, black skeletonized bridges, and a manually wound flying tourbillon movement with hours and minutes, delivering a similar on-wrist impression and visual complexity. [1]

Key Specifications at a Glance

Carbon Case, Skeleton Architecture & Wrist Presence

The star of this NF V4 edition is the genuine multi-layer carbon fiber case, carved from a solid block rather than molded plastic, giving each watch a unique organic grain pattern reminiscent of wood or forged composites. [1]

This construction dramatically reduces weight compared to steel or titanium, creating a “barely there” sensation on the wrist while still delivering the thick, sculpted Excalibur silhouette and aggressive notched bezel. [1]

The fully skeletonized dial reveals a dual-layer movement layout, with a black PVD astral star bridge floating above the mainplate to create a deep, three-dimensional effect when viewed from different angles. [1]

At 7 o’clock, the functional flying tourbillon cage provides constant animation as it completes a full 360-degree rotation every minute, acting as both a technical focal point and the visual heartbeat of the watch. [1]

Paired with a black natural rubber strap and DLC-coated titanium folding clasp, the watch hugs the wrist securely and comfortably, making the radical design surprisingly wearable for extended daily use. [1]

Wear, Styling & Everyday Versatility

Despite its high-concept movement and skeletonized construction, this Excalibur Spider Carbon homage has been designed as a versatile piece that can move between casual and evening environments. [1]

The all-black carbon case, black bridges and black rubber strap give it a stealthy, monochromatic look that pairs easily with streetwear, technical outerwear or minimalist monochrome outfits. [1]

At around 42 mm in diameter, it offers serious wrist presence without overwhelming most wrists, while the low weight of the carbon and flexible strap keep it comfortable enough for all-day wear. [1]

In low light, the sculptural forms of the skeleton bridges and tourbillon cage catch reflections from the AR-coated sapphire crystal, giving the watch a subtle depth and intrigue even when the technical details are not fully visible. [1]

For collectors who already own more traditional steel sports watches or dress pieces, this model adds a dramatically different, ultra-modern counterpoint to the collection, emphasizing architecture and material innovation over conventional dial layouts. [1]

Performance, Movement & Handling

Inside this NF Roger Dubuis Excalibur Spider Carbon RDDBEX0508 replica is a custom, manually wound flying tourbillon movement built specifically for openworked presentation and visual impact. [1]

The movement is skeletonized to create a dual-layer effect, with key components exposed on both the dial and caseback sides, and the tourbillon cage precisely aligned at 7 o’clock for balance and symmetry. [1]

Being a mechanical tourbillon calibre, it rewards regular interaction: winding the crown becomes part of the ownership ritual, and watching the cage rotate once per minute offers a constantly changing view of the escapement in motion. [1]

The watch is tuned for reliable daily use, but as with all tourbillon mechanisms, it should be protected from strong shocks, drops or high-impact sports to preserve accuracy and longevity. [1]

With a water resistance rating of 3 ATM, it is suitable for everyday splash exposure such as handwashing or light rain, but it should not be worn for swimming, showering or water sports to avoid moisture ingress through the complex skeleton case structure. [1]

Premium 1:1 Homage – Compliance & Transparency

This timepiece is a high-quality 1:1 homage replica inspired by the Roger Dubuis Excalibur Spider Carbon RDDBEX0508 and is not an official product, not manufactured, endorsed or authorized by Roger Dubuis or any related entity. [1]

All branding style, design cues and specifications are used purely to describe the aesthetic and functional inspiration behind this independently produced watch, allowing enthusiasts to enjoy the look and feel of the original concept at a more accessible level. [1]

The use of genuine multi-layer carbon fiber, a functional flying tourbillon and a fully skeletonized architecture distinguishes this NF V4 edition from lower-tier replicas that rely on printed patterns or non-functional decorative movements. [1]

Buyers should understand that movement architecture, finishing standards and materials, while premium for a replica, are different from the proprietary components used in the genuine manufacture model and are not represented as being identical. [1]

Positioned honestly as a homage replica, it offers a compelling way to experience the radical design language of the Excalibur Spider Carbon on the wrist while remaining transparent about its independent origin and replica status. [1]
