- Breaking away from conventional designs, Roger Dubuis introduced the Excalibur collection in 2005, showcasing a futuristic and innovative approach. Through the implementation of a skeletonized dial construction, the brand revolutionized their timepieces, presenting a striking departure from their previous designs. Over time, the collection has evolved, incorporating various complications and case materials, further solidifying their position in contemporary watchmaking.

- In addition to their technical advancements, Roger Dubuis has embarked on collaborations with renowned brands, such as Lamborghini Squadra Corse. The Excalibur Spider Monobalancier Huracán houses the RD630 movement, which was specifically developed for this partnership. The caliber structure of the watch resembles that of a high-performance car engine, with strut-bars serving as a distinct visual signature. The inclusion of a super car wheel rim-like rotor adds a subtle yet captivating motorsports aesthetic.

- Encased in ceramic composite fiber, the watch boasts a lightweight and durable construction, complemented by its sleek white appearance. Limited to just 88 pieces, this particular iteration of the Excalibur Spider is an exceptionally rare find in today's market.
