This is the Sang Bleu II to choose if the case geometry is what pulled you in. The sharp green ceramic faceting, the openworked dial with geometric time display, and the correctly integrated black rubber strap give this piece its whole identity. Compared with standard Big Bang executions from other factories, the BBF build matters here because this reference depends on crisp edges rather than simple round case finishing. Read the full description for the details that decide whether this 45mm case will suit your wrist and taste.
The green ceramic case is the entire point of this watch
One look at the faceted green ceramic case tells you whether the Sang Bleu II belongs in your collection. This is not a conventional Big Bang with a familiar round-bezel personality. The appeal sits in the angular architecture: hard transitions, deep planes, and a bezel that changes character as light moves across brushed surfaces and polished edges. On this BBF edition, that geometry is the reason to pay attention, because this reference only works when those lines stay crisp and properly defined.
The 45mm case is built in green ceramic with a multi-piece construction, and that matters both visually and on the wrist. Ceramic gives the color a solid, uniform look that suits the tattoo-inspired design language of the Sang Bleu line. If you are considering this piece, the decision is usually less about brand recognition and more about whether you want a watch that reads like wearable industrial sculpture from across the room.
The dial trades classic legibility for strong visual character
The dial is skeletonized and layered with geometric forms rather than traditional hands and markers. Green accents tie the display back to the case, while the open structure keeps the watch from feeling flat or overly heavy in appearance. At 3 o’clock, the 60-minute chronograph counter remains present, and the skeletonized calendar ring is visible through the dial architecture. That combination gives the watch mechanical depth without cluttering the face with standard chronograph styling.
This is a piece for someone who appreciates visual tension more than instant readability. The geometric display is part of the attraction. It gives the watch a distinctly architectural feel that separates it from more conventional skeleton chronographs. If you already own round, balanced sports watches, this is the one that adds a very different voice to the rotation.
Why BBF matters on the Sang Bleu II
Factory talk is usually secondary, but on this reference it does help explain the value. BBF has earned its reputation here because the Sang Bleu II case is unusually demanding. The sharp ceramic facets, the multi-piece structure, and the specific dimensional relationships between bezel, mid-case, and lugs are harder to execute than a standard Big Bang format. That is why knowledgeable buyers often treat BBF as the benchmark for this particular model rather than simply another option in the category.
The movement is the clone HUB 1240 automatic chronograph with an approximately 36-hour power reserve. It supports the functional 60-minute counter and the skeletonized date layout while carrying the unconventional geometric display. That is a meaningful point for a buyer deciding between watches that are visually similar in photos but differ in how faithfully they handle the dial architecture and operating layout.
The strap and clasp keep the watch visually disciplined
The black integrated rubber strap is the correct choice for this model. It gives the vivid green case a clean boundary and keeps the design from becoming visually overloaded. The geometric channels in the strap echo the case language, and the deployant clasp preserves the structured, technical feel when the watch is off the wrist as well. The clasp visible in the photos is dark-toned, which suits the watch better than a brighter metallic interruption would.
This also helps explain who the watch suits best. The Sang Bleu II has substantial wrist presence, and the rigid lug structure means it is better for someone comfortable with a bold 45mm case. If you want your statement watch to come from shape and finishing rather than from gemstone excess or bright metal flash, this reference gets there in a much smarter way.
A specialist choice, not a safe one
The best reason to buy this watch is that it does not try to please everyone. The green ceramic, the faceted bezel with H-shaped screws, the sculptural dial, and the visible caseback together create a watch that feels deliberate at every angle. It is for the collector who already understands the usual sports-watch formulas and wants something that breaks them with purpose.
If that is your lane, this Sang Bleu II makes a strong case for itself. It offers the unusual case architecture that defines the reference, a correctly matched black rubber strap, and the kind of visual depth that gives you something new to notice each time it is on the wrist.
