Hublot Big Bang 418.CX.1114.RX.MXM20 Black Skeleton Dial 45mm

Hublot Big Bang Unico Sang Bleu II All Black 418.CX.1114.RX.MXM20

The Hublot Big Bang Unico Sang Bleu II All Black is the result of a distinctive collaboration between Hublot and Swiss-French tattoo artist Maxime Plescia-Buchi, founder of the Sang Bleu creative collective. Known for his geometric tattoo language and architectural design style, Plescia-Buchi reinterpreted the Big Bang platform through sharp lines, layered structures, and angular forms.

This particular reference, 418.CX.1114.RX.MXM20, is part of a limited production of only 200 pieces, making it one of the more exclusive interpretations within the Sang Bleu series. The watch embraces Hublot’s well-known “All Black” concept, where materials, finishes, and components are unified in a monochromatic palette to emphasize form, depth, and structure rather than color contrast.

The result is a chronograph that feels almost sculptural. Instead of a traditional dial and case design, the watch presents an architectural composition where bridges, hands, and movement elements become part of the visual identity.

Case Design and Black Ceramic Construction

The watch features a 45mm case made from black ceramic, finished with alternating satin-brushed and polished surfaces. Ceramic is widely appreciated in modern watchmaking due to its high resistance to scratches, long-term durability, and ability to maintain a consistent deep color over time.

Despite its bold dimensions, ceramic also contributes to a relatively lightweight feel compared with traditional steel cases of similar size.

The bezel continues the same black ceramic theme and is secured by six H-shaped titanium screws, coated in black to maintain the monochromatic aesthetic. This construction not only reinforces the structural design of the watch but also remains one of the defining elements of the Big Bang watches.

The overall result is a case that feels technical and architectural rather than decorative.

Geometric Skeleton Dial

One of the most distinctive aspects of the Sang Bleu II design is its skeletonized dial structure, which exposes much of the underlying movement architecture.

Instead of traditional circular chronograph registers, the dial uses angular bridges and geometric cutouts inspired by Sang Bleu’s tattoo language. Lines intersect, shapes overlap, and layers create depth across the dial surface.

The hands themselves follow this geometric theme. Rather than simple straight hands, they adopt polygonal shapes that align with the visual language of the case and dial.

Even with the skeletonized design, readability remains strong. Luminous treatment on the hands and markers ensures the time can still be read clearly in most lighting conditions.

HUB1240 Unico Manufacture Movement

Inside the case is the HUB1240 Unico manufacture movement, an in-house automatic flyback chronograph developed by Hublot for sale. This calibre represents one of the brand’s most technically advanced chronograph movements.

The movement consists of approximately 330 individual components and operates at a frequency of 4 Hz, ensuring stable timekeeping and smooth chronograph operation.

One of the key mechanical features is the column-wheel flyback chronograph system, which allows the chronograph to be reset and restarted instantly with a single push. This function is often appreciated by collectors due to its mechanical sophistication and practical usability.

The movement also offers an impressive 72-hour power reserve, allowing the watch to run for roughly three days when fully wound.

Through the sapphire case back, the movement architecture and rotor are visible, giving collectors a clear view of the mechanical complexity behind the design.

Strap and Wearing Experience

The watch is fitted with Hublot’s black rubber strap, a material the brand has long been known for integrating into luxury sports watches. Rubber provides flexibility, durability, and comfort during extended wear.

The strap integrates seamlessly with the case and is secured by a deployant buckle crafted from black ceramic and black-plated titanium, maintaining the full monochromatic identity of the watch.

Despite the bold geometry and complex dial architecture, the watch remains wearable thanks to the combination of ceramic construction and the flexible rubber strap.

Limited Edition and Collector Appeal

This reference is produced in a limited run of only 200 pieces worldwide, adding an additional layer of exclusivity for collectors.

The Sang Bleu II series represents a unique intersection between watchmaking, contemporary art, and tattoo culture. Rather than simply applying decorative elements, the collaboration integrates artistic geometry directly into the structural design of the watch.

For collectors who appreciate unconventional watch design, the Big Bang Unico Sang Bleu II All Black stands apart from more traditional chronographs. It emphasizes architecture, mechanical exposure, and monochromatic design while maintaining the performance expected from Hublot’s Unico chronograph platform.
