The BBF Factory Hublot Big Bang Sang Bleu II 45mm replica is a horological convergence of haute watchmaking and tattoo artistry. Conceived in collaboration with world-renowned tattoo artist Maxime Plescia-Büchi of Sang Bleu studio, this limited-edition timepiece is the second iteration of a celebrated partnership that began in 2016—translating the needle’s indelible geometry into a wearable sculpture. The Sang Bleu II elevates the original with the in-house UNICO automatic flyback chronograph movement in place of a base chronograph, while adding even more radical 3D depth and layered complexity to the geometric motif. The motif now seems to penetrate the case, cut into the bezel, carve through the sapphire crystal, and extend into the interchangeable strap, making every visible surface an extension of the pattern

The fully skeletonized geometric dial is a mesmerizing labyrinth of triangles, parallelograms, and hexagons arranged in multi‑layer, nested structures. Hours and minutes are indicated by the prominent arrow‑like and diamond‑tipped hands positioned at the intersections of these geometric fields—a design that requires a moment of orientation but rewards with an authentic Plescia-Büchi reading experience. The 9 o‘clock small seconds subdial completes the asymmetric layout. At 6 o’clock, the visible column wheel of the replica HUB1240 movement confirms the authenticity of the flyback chronograph function, a signature that distinguishes UNICO calibres from standard chronographs.

The watch is fitted with a structured rubber strap and the One Click quick‑change system, allowing effortless strap swaps without tools. A signed folding buckle (titanium, ceramic‑trimmed, or gold-plated, matching the case material) completes the secure, comfortable setup. For the diamond‑set models (pavé versions), the bezel and case band feature precisely channel‑set stones that mirror the original’s jewel count and arrangement.
