Starting with the Basics
Identifying your Hublot Big Bang Sang Bleu begins with close attention to its dial pattern, case size, bezel screws and reference markings. These details reveal the precise generation and variation you own.
Begin by examining the case, caseback, engravings and movement. The Big Bang Sang Bleu family is known for its distinctive geometric dial inspired by the work of tattoo artist Maxime Plescia-Büchi. Look at the overall shape of the lugs and the arrangement of the six H-shaped titanium screws on the bezel. These elements help establish whether you have an earlier or later interpretation within the collection.
Note the material of the case, which may be ceramic, titanium or King Gold. The dial features overlapping geometric shapes forming a mandala-like pattern. Count the number of main overlapping circles or observe the finish of the hands and hour markers. These visual cues narrow down the specific model without needing external tools at first.
The size of the watch on the wrist also provides an immediate clue. Case size is worth recording, and the proportions of the crown and pushers can differ subtly between versions. Write down everything you observe before moving to more detailed checks.
The History and Design Story
Hublot introduced the Big Bang Sang Bleu in 2016 as part of its continuing development of the Big Bang line. The collaboration with Maxime Plescia-Büchi brought a bold, graphic aesthetic drawn from sacred geometry and tattoo art. The name Sang Bleu, meaning blue blood in French, comes from Maxime Plescia-Büchi's tattoo studio and brings that graphic language into watchmaking.
The original Sang Bleu established a signature look with its complex dial composed of intersecting lines, circles and triangular forms. Subsequent versions refined this language, introducing new materials and slight adjustments to legibility and finishing. Each iteration maintained the core DNA while responding to evolving collector tastes and technical capabilities.
Over the following years the collection grew to include variations that altered the balance of the dial elements or introduced different case constructions. These changes were never drastic but reflected Hublot's constant experimentation with textures, colours and materials such as titanium and ceramic. The design remains instantly recognisable across all versions.
Identifying the Exact Version
To determine the precise version, first measure or estimate the case diameter by comparing it to known objects or simply noting how it sits on your wrist. Look closely at the dial layout. Earlier models show the original geometric pattern, while later executions such as Sang Bleu II use a more layered construction and may differ in hand luminescence.
Check the bezel carefully. The finish of the six H-shaped screws is worth noting with the other case details. Record the screw finish you see, rather than assuming one standard treatment. The material of the case itself, whether matte ceramic, polished King Gold or a mix, further distinguishes one from another. The strap or bracelet type, its width at the lugs and the deployment clasp mechanism also offer identifying information.
Turn the watch over and study any visible markings on the caseback. Even without opening the watch, the style of engraving or presence of certain inscriptions can point to a particular generation. Combine these observations with the colour of the subdials or the style of the central hands to build a clear picture of which Sang Bleu you own.
Comparing Related Models and Sizes
The Big Bang Sang Bleu family is built around a bold case, and each execution has its own character. The geometric intensity remains consistent, while case proportions and wrist presence shape how the dial is read. The relationship between case size and lug width affects the overall presence and how the bracelet or strap integrates with the design.
Many executions use Hublot's Unico chronograph, which is visible through the caseback. The rotor and its finishing are useful to record alongside the reference and case details. These distinctions separate regular models from limited editions, although the core dial architecture remains consistent.
When comparing your watch to images of known examples, focus on the angle of the bezel edges, the thickness of the case and the way light reflects off the geometric dial layers. These physical traits often prove more reliable than memory alone. Note that strap changes over time can make two similar versions appear different at first glance.
How Condition Affects Assessment
Condition plays a central role in how any watch is evaluated. For the Big Bang Sang Bleu, pay particular attention to the sharp edges of the geometric dial elements, which can show wear under close inspection. The case corners, bezel screws and crown guards should be examined for any loss of definition or surface marks.
The strap or bracelet receives equal scrutiny. Links on metal versions can develop stretch or polish loss, while rubber straps may show creasing or edge wear. The way the watch has been stored also matters, as prolonged exposure to certain environments can affect the finish of the case materials.
Completeness matters too. The presence of the original buckle, any fitted links or correct end pieces helps confirm the version. Even without all accompanying items, however, the watch itself tells the clearest story through its physical state and construction details.
Photography Guidance for Valuation
Clear, well-lit photographs are essential for an accurate initial assessment. Take multiple images of the full watch from directly above, at a 45-degree angle and from the side to show case thickness. Capture the dial straight on so the geometric patterns are perfectly centred and evenly lit.
Include close-ups of the bezel screws, the crown and any visible markings on the case or clasp. Photograph the caseback in its entirety, ensuring engravings are readable. A clear shot of the movement helps confirm the version. Use natural daylight where possible and avoid strong shadows.
Take detailed images of any areas showing wear, however minor. These help us understand the overall condition accurately. Photograph the strap or bracelet both attached and, if possible, laid flat to show its construction and hardware. Several angles of the clasp or buckle complete the set.
Understanding Materials and Markings
The Big Bang Sang Bleu has been produced in a variety of materials, each bringing a different visual weight to the geometric design. Ceramic versions offer a matte or polished finish that contrasts with the dial layers, while King Gold provides warmth and depth. Titanium versions add a lighter, contemporary feel that reads differently under changing light.
Markings on the dial are usually minimal, allowing the pattern to dominate. Look for small text near the bottom of the dial or on the flange. The hands and markers may be finished in different tones or with different coatings depending on the version. These subtle choices distinguish one generation from the next.
On the case and clasp, engravings provide further confirmation. Serial numbers, if present, and any model-specific stamps help verify authenticity and period. The style of the Hublot logo on the dial or clasp can also evolve slightly across the years, offering another quiet identifier.

Questions sellers ask
Can I identify my Hublot Big Bang Sang Bleu without the original papers? Yes. The physical details of the case, dial pattern, bezel screws and markings usually provide enough information to determine the exact version.
What is the most reliable way to distinguish between different Sang Bleu generations? Case material, dial construction and reference markings offer the clearest distinctions between earlier and later versions.
Do small differences in dial colour affect identification? Subtle variations in tone or luminescence can indicate a specific edition. Combined with case details they help confirm which exact model you own.
Why does EncoreLuxe need to inspect the watch in person? Photographs are extremely helpful but cannot convey every surface nuance, material texture or movement detail that becomes apparent upon physical examination.
How should I photograph the geometric dial for best results? Take a perfectly centred, evenly lit straight-on shot so all overlapping shapes and markers are clearly visible without glare or shadow.
What happens if my watch does not match the initial assessment? We discuss any differences with you. If you choose not to proceed we return the watch free of charge and fully insured.
