Hublot’s Spirit of Big Bang Impact is back with a sharper material story and a more technical approach to decoration.
The new 42mm tonneau-shaped collection arrives as a trio of limited editions, using sapphire, crystallized osmium, black ceramic and diamonds to revisit one of the brand’s most recognisable contemporary design codes.
It also gives the Nyon manufacture a new gem-setting milestone, with diamonds set directly into sapphire for the first time in its watchmaking.
At a glance
- Hublot has introduced three limited-edition Spirit of Big Bang Impact models in sapphire, sapphire with diamonds and black ceramic.
- The standout piece features 145 fancy-cut diamonds set across the bezel and dial, including diamonds placed directly into sapphire.
- The editions are limited to 20, 30 and 100 pieces, with each watch covered by Hublot’s 5+5 warranty for up to ten years.
A sharper evolution of the Impact Bang pattern
The collection marks ten years since the debut of Hublot’s Impact Bang pattern, a fractured, architectural motif that sits naturally within the brand’s Art of Fusion vocabulary.
Rather than using the design as surface decoration alone, the new Spirit of Big Bang Impact watches build the pattern around the dial architecture, bezel and moon phase display at 6 o’clock.
The effect is intentionally dynamic, with the dial appearing to break outward from the moon phase indication in a controlled burst of angular forms.
Each decorative element is positioned by hand, which matters here because the design depends on alignment, proportion and light rather than simple symmetry.
Sapphire and osmium take the collection into rare territory
The Sapphire edition leans into transparency, using a sapphire crystal case that exposes the mechanical and architectural layers of the watch.
Its distinctive accent comes from crystallized osmium, a material prized for its rarity and bluish reflections.
Within Hublot’s material-led universe, that combination makes sense because it avoids treating sapphire as a purely invisible shell.
Instead, the clear case becomes part of a broader study in light, reflection and depth.
The Sapphire Jewellery edition pushes the concept further with a polished sapphire case and 145 fancy-cut diamonds across the bezel and dial.
The technical talking point is the diamond setting itself, as Hublot has set stones directly into sapphire, a particularly demanding material because of its hardness and brittleness during machining.
That makes the Jewellery model more than a high-jewellery variation of the same watch.
It becomes a showcase for how far the brand can take gem-setting within non-traditional watchmaking materials.
All Black keeps the drama in ceramic
The third model turns away from transparency and gem-setting in favour of Hublot’s long-running All Black language.
Its black ceramic case combines polished and microblasted surfaces, creating contrast without relying on colour.
That restraint gives the Impact pattern a different character, with the fragmented geometry appearing more graphic and shadow-led.
For collectors who prefer Hublot’s darker, sportier side, this is likely to be the most wearable interpretation of the trio.

The HUB1770 keeps the display intentionally theatrical
All three versions use Hublot’s self-winding HUB1770 in-house caliber, a skeletonized movement made from 288 components.
The display is deliberately asymmetrical, with central hours and minutes, a small seconds sub-dial at 9 o’clock, moon phases at 6 o’clock and a large date positioned at 1 o’clock.
That layout suits the case and dial treatment because it gives the eye multiple points of tension rather than a conventional central hierarchy.
The movement offers around 50 hours of power reserve, which keeps the watch practical enough for regular rotation despite its highly expressive construction.
Each model is fitted to a textured rubber strap using Hublot’s One-Click interchangeable system, reinforcing the collection’s blend of technical watchmaking and everyday sport-luxury usability.
With the three editions capped at 20, 30 and 100 pieces, the Spirit of Big Bang Impact is aimed squarely at collectors drawn to Hublot’s most experimental side.
It’s a confident anniversary evolution, not because it simply adds precious materials, but because it uses sapphire, osmium, ceramic and diamonds to make the collection’s fractured architecture feel newly relevant.
