Hublot has brought its Impact concept back for 2026, this time moving the shattered visual language onto the tonneau-shaped Spirit of Big Bang Moonphase platform.
The new Spirit of Big Bang Impact arrives as three limited editions, each using the same asymmetrical moonphase layout but taking a very different approach to material, texture and price.
The Impact motif works unusually well on the moonphase dial
The original Impact idea appeared in 2016 on a Big Bang model with interlocking diamond forms arranged to look like the watch had fractured across the surface.
For this return, Hublot has chosen the Spirit of Big Bang Moonphase, a less obvious but surprisingly effective canvas because its date, moonphase and running seconds displays already break up the dial.
The result feels more coherent than a simple decorative overlay, with the fragment-shaped appliqués appearing to float over the movement and frame the indications rather than fight them.
All three versions measure 42mm across, with the black ceramic model coming in at 14.6mm thick and the sapphire-cased versions measuring 15.5mm thick.
Black ceramic, sapphire and a rare osmium dial
The most accessible model in the trio is the Spirit of Big Bang Impact All Black, reference 647.CX.0140.RX.IMP26, limited to 100 pieces and priced at $33,700.
Its polished and micro-blasted black ceramic case is paired with mirror-polished black appliqués, giving the watch the strongest frozen-mid-explosion effect of the three.
The Spirit of Big Bang Impact Sapphire, reference 647.JX.0106.RW.IMP26, is limited to 30 pieces and priced at $114,500.
This version places the fragmented dial inside a transparent sapphire case, alternating polished rhodium with crystallized osmium, a metal prized for its rarity, density and pale blue sparkle when crystallized.
It is arguably the most visually compelling of the set because the osmium gives the dial a sharper, more mineral-like brilliance than a conventional gem-set treatment.
Diamond-set sapphire pushes the concept further
The most exclusive model is the Spirit of Big Bang Impact Sapphire Jewelry, reference 647.JX.9000.RW.1904.IMP26, limited to 20 examples and positioned well into six-figure territory.
Its sapphire case carries 54 fancy-cut diamonds on the bezel, while another 91 fancy-cut diamonds continue the fragmented pattern across the dial.
This is a notable technical exercise for Hublot because setting diamonds into sapphire is far more difficult than setting them into metal.
Each stone is unique in size and cut, and the settings use polished gold channels secured within laser-cut mounts between framing strips in the sapphire bezel.
A familiar Zenith-derived moonphase caliber inside
All three models run on the HUB1770 automatic movement, the same caliber used in the Spirit of Big Bang Moonphase.
The 27-jewel movement has 288 components, runs at 28,800 vibrations per hour and delivers a 50-hour power reserve.
Its architecture comes from Zenith, Hublot’s LVMH stablemate, and the quality of the underlying movement is not in question.
The compromise is visual rather than mechanical, since the round movement is visible through the back of a tonneau case, which leaves the rear view less integrated than the ambitious dials suggest.
The black ceramic model offers 100 meters of water resistance, while the sapphire versions are rated to 50 meters.
Each watch is fitted with Hublot’s One-Click strap system, with the black ceramic version on a black textured rubber strap and the sapphire models on white textured rubber straps.
As with many Spirit of Big Bang models, the 42mm tonneau case has real wrist presence, so these are not discreet watches despite the elegance of the moonphase complication.
The Spirit of Big Bang Impact will appeal most to collectors who like Hublot at its most material-driven, especially those drawn to the contrast between a classical lunar display and a dial that looks deliberately fractured.
