The Hublot Moonphase Impact 2026 marks one of the boldest releases of the year. It arrives as part of the famous Spirit of Big Bang family. However, this time the news goes well beyond a styling refresh. In fact, the collection introduces a technical first. No Hublot has ever achieved it before. Moreover, the new lineup comes in three limited editions. They differ dramatically in materials, finishing, and price. This makes it a release every serious watch enthusiast should follow. In this article on gearsme.com, we break down all three references. We also cover their technical specifications and official prices. Plus, we give you an honest take on where each one sits in the market.
A Quick Look at the Spirit of Big Bang Collection
First, it is worth remembering the roots of this line. The Spirit of Big Bang was launched under Jean-Claude Biver. It was the first entirely new case shape from Hublot after the original Big Bang. Since then, the brand has replaced the octagonal case with a tonneau silhouette. The lateral rubber bumpers stayed. So did the signature H-shaped bezel screws. The skeletonised dial also remained, revealing the movement underneath.
Consequently, the Hublot Moonphase Impact 2026 builds on that legacy. However, it pushes the volume much higher. The new collection revives the visual identity of the 2016 Big Bang Impact Bang. Moreover, it adds a fresh layer of technical innovation. This is especially true when it comes to setting diamonds directly into sapphire crystal.

What Sets the Hublot Moonphase Impact 2026 Apart?
First, all three references share the same core DNA. It defines the collection and includes:
- 42mm tonneau case with the signature H-shaped screws on the bezel
- Rubber strap with a titanium deployant clasp
- HUB1770 automatic skeletonised calibre, beating at 4Hz with a 50-hour power reserve
- Big date at 1 o’clock and a moon phase display at 6 o’clock
However, the differences between the three editions are more interesting than the shared platform. In particular, they diverge in materials, gem-setting, and dial treatment. In addition, Hublot has pushed the complications into a supporting role. The moon phase and big date let the visual design take centre stage. On the other hand, each reference has its own personality. As a result, the trio feels like three different readings of one concept.
The Three Hublot Moonphase Impact 2026 References
1. Spirit of Big Bang Moonphase Impact Sapphire Jewellery
First up is the most technically ambitious piece in the collection, and genuinely a first in Hublot’s history. For the very first time, diamonds have been set directly into a sapphire crystal case. Moreover, the bezel carries 54 fancy-cut diamonds (non-round stones with countless facets that sparkle like a disco ball), seated in polished gold channels and inserted into laser-machined mounts within the sapphire. Additionally, the dial adds another 91 fancy-cut diamonds, arranged to mimic shards flying outward from a point of impact.
However, because the gem-setting almost completely covers the dial, Hublot added a strip of Super-LumiNova to the hour, minute, and small seconds hands to keep the watch legible. On the other hand, the big date and moon phase become barely visible, which some buyers will see as a pure design statement rather than a functional compromise.
- Case thickness: 15.5mm
- Water resistance: 50m
- Reference: 647.JX.9000.RW.1904.IMP26
- Limited to: 20 pieces
- Price: CHF 450,000 / EUR 532,000
2. Spirit of Big Bang Moonphase Impact Sapphire (Osmium)
Second, this reference keeps the sapphire crystal case but replaces diamonds with a material that is arguably even rarer: crystallised osmium. In fact, osmium is widely considered the rarest stable element on Earth. Furthermore, it is denser and harder than platinum, and it carries a natural bluish shimmer that sets it apart visually. Since osmium is unstable in its raw form, Hublot partnered with Swiss scientists in the Valais region to develop a crystallisation process that makes it suitable for use in fine watchmaking.
In addition, the dial and bezel alternate sharp osmium shards with rhodium-plated counterparts, producing a cooler, more scientific interpretation of the impact theme. As a result, this edition is clearly aimed at collectors who value rare materials over traditional gemsetting.
- Case thickness: 14.25mm
- Water resistance: 50m
- Reference: 647.JX.0106.RW.IMP26
- Limited to: 30 pieces
- Price: CHF 95,000 / EUR 112,200
3. Spirit of Big Bang Moonphase Impact All Black
Finally, the third reference celebrates 20 years of Hublot’s legendary “All Black” concept, an idea built around trading easy legibility for a purely monochromatic, texture-driven aesthetic. Consequently, the case, bezel, and dial are all executed in black ceramic. Furthermore, the bezel is engraved with the impact motif, while the dial uses black-plated polished appliques and black hands filled with black Super-LumiNova, which preserves the all-black look even in low light.
On the other hand, this is also the most wearable of the three, and by a significant margin the most accessible in terms of price. In addition, it offers the highest water resistance in the trio, making it the most practical option for daily use.
- Case thickness: 14.6mm
- Water resistance: 100m
- Reference: 647.CX.0140.RX.IMP26
- Limited to: 100 pieces
- Price: CHF 28,000 / EUR 33,100
Inside the Movement: The HUB1770 Skeletonised Calibre
All three Hublot Moonphase Impact 2026 models run on the same engine: the HUB1770 automatic skeletonised calibre with a moon phase function. Specifically, the movement contains 288 components and 27 jewels, beats at 28,800 vph (4Hz), and delivers a 50-hour power reserve. Moreover, the functions include hours, minutes, small seconds, big date, and moon phase.
However, this is not a brand-new calibre, but the choice still makes sense here. In reality, its skeletonised architecture allows the dial to “breathe” and showcases the impact motif without visual noise. In addition, the HUB1770 has already proved itself across several previous releases in Hublot’s limited edition watches catalogue, which reinforces its reliability.

Who Is the Hublot Moonphase Impact 2026 For?
Honestly, this collection does not try to be subtle, and it does not pretend to be. Therefore, the Sapphire Jewellery edition is clearly aimed at the collector who already owns serious Hublot pieces and is looking for the “next technical flex” to add to the watch box. On the other hand, the osmium version speaks to buyers who care far more about material rarity than carat weight. In contrast, the All Black ceramic model remains the most realistic option for daily wear, and the only one priced below the CHF 30,000 mark.
In addition, anyone considering a purchase should factor in wrist presence. For example, the 15.5mm thickness of the Sapphire Jewellery reference might feel substantial on smaller wrists, while the All Black model sits more comfortably for everyday use.
Availability and Official Prices
All three references are confirmed limited editions and will be distributed through Hublot boutiques and authorised retailers. For more information, you can visit the official Hublot website. In addition, based on how past Spirit of Big Bang releases have performed, the Sapphire Jewellery edition is expected to be allocated quickly, particularly in the Middle East and Asian markets, where high-jewellery watches tend to move fast.
Final Verdict: Is the Hublot Moonphase Impact 2026 Worth It?
Ultimately, the Hublot Moonphase Impact 2026 reinforces the brand’s identity built on “fusion of materials,” but it also delivers a genuine technical milestone: diamonds set directly into sapphire crystal for the first time. However, whether you read the design as daring or as over-the-top depends entirely on personal taste. Regardless, this release is easily the most ambitious Spirit of Big Bang in years. As a result, it deserves attention from any serious watch enthusiast, even from those who would never wear a Hublot on their own wrist.
