For a buyer who wants the Sang Bleu II for its case architecture rather than just the name, this is the one to focus on. The deciding details are the multi-faceted grey ceramic build, the openworked geometric display with the date at 4:30, and the integrated grey-and-black rubber strap that keeps the design coherent on the wrist. Against simpler steel-based alternatives, this execution stands out for its true ceramic construction and dial-side UNICO-style chronograph layout. The detailed description matters here because this watch is all about structure, movement display, and how those elements actually work together.
The grey ceramic case is the whole point
This Big Bang Unico Sang Bleu II makes its case immediately through shape. The 45mm body is built around sharp geometric planes, alternating brushed and polished surfaces, and a faceted grey ceramic bezel secured with H-shaped screws. That matters because this reference lives or dies by its architecture. On the wrist, the muted grey tone gives the watch a cooler, industrial look than black ceramic, while the crisp edges keep the Sang Bleu design from looking soft or over-styled.
BBF is worth noting here for one specific reason: this reference depends on a complex 12-piece ceramic case construction. That execution is what preserves the deep angles, separate facets, and sculpted transitions that make the Sang Bleu II different from an ordinary Big Bang. If you are comparing versions, that is the practical reason to choose this one over cheaper interpretations that flatten the case or replace ceramic with coated metal.
The dial stays dramatic without losing function
From the front, the watch is unmistakable. The skeletonized display layers white geometric disc hands over a dark grey openworked base, with visible gearing and the date ring set into the lower-right portion of the dial at 4:30. The contrast is strong enough that the angular display remains readable once you understand the layout, and the open dial gives the watch the mechanical depth this design needs.
This is not a conventional chronograph face with clear subdials doing all the visual work. Instead, the Sang Bleu II approach uses geometry as both design and display. The result is much more architectural than a standard sports chronograph, which is exactly why collectors tend to choose this reference in the first place. If your interest is in unusual dial structure rather than a safe everyday Hublot, this piece delivers the right kind of visual complexity.
Clone HUB 1240 makes this version relevant
Inside is the clone HUB 1240 automatic flyback chronograph with approximately 36 hours of power reserve. The key appeal is not just the name of the movement, but the way it supports the watch’s visible layout. You get a fully functional 60-minute timing module, a horizontal clutch visible around 8 o’clock on the dial side, and a functioning calendar ring that reads through the 4:30 aperture. Those details are important because they preserve the UNICO-style character that knowledgeable buyers look for in this model.
The movement also has enough torque to drive the heavy geometric display system, which is a real consideration on this design. That makes this watch a much stronger choice than generic chronograph builds used in less accurate alternatives, especially if your priority is getting the visual mechanics and operating feel closer to what this reference is supposed to offer.
The integrated strap finishes the watch properly
The strap is a structured integrated rubber design in grey with black outer framing, and it follows the case lines cleanly instead of looking like an afterthought. That continuity is important on a Sang Bleu II because the watch relies on uninterrupted geometry from lug to clasp. The clasp itself is a deployant style, and the visible Hublot-signed top section keeps the closure in line with the rest of the design language.
This is also a large-format watch with a broad, assertive stance, so it suits buyers who want the full sculptural effect rather than a toned-down interpretation. If that is your goal, this reference makes sense because every visible component, from the faceted bezel to the integrated rubber strap, contributes to one consistent idea instead of mixing a dramatic dial with a generic case or bracelet.
Who this watch suits best
This piece is best for the buyer who already understands that the Sang Bleu II is about design tension: sharp case geometry, exposed mechanics, and a display that feels closer to wearable industrial art than to a standard chronograph. The grey ceramic execution keeps that concept refined and technical rather than loud. If you want a Hublot that stands apart even within the Big Bang family, this is one of the clearest expressions of that brief.

Buyer Q&A
Questions about this Hublot watch
How is the time displayed on this Sang Bleu II?
The watch uses rotating geometric disc hands rather than conventional baton hands. The angular white display elements sit over the skeletonized dial and are designed around the Sang Bleu layout.
Does this watch have a working date display?
Yes. The date is shown through an aperture at 4:30, and the dial layout also reveals the calendar ring within the openworked design.
What makes this version worth choosing over simpler alternatives?
Its appeal is the combination of a 12-piece grey ceramic case and the clone HUB 1240 flyback chronograph architecture. That gives this reference the sharp faceted case structure and dial-side mechanical layout that define the Sang Bleu II.
