Hublot marked 20 years of the Big Bang in 2025 with five limited-edition 43 mm watches that pair the collection’s layered case and carbon-pattern dial with the brand’s Unico flyback chronograph. The editions range from black and red ceramic to King Gold and Magic Gold, with announced quantities of 100 to 500 pieces. In January 2026, Hublot followed them with the Big Bang Original Unico, a separate collection release that reworks the original design rather than extending the anniversary capsule.
What the 20th-anniversary collection includes
Hublot’s 1 April 2025 announcement describes five limited editions. Every watch has a 43 mm case and shares the anniversary design and movement; the editions differ principally in case materials, color, and announced quantity.
| Edition | Announced quantity | Material and appearance |
|---|---|---|
| Titanium Ceramic | 500 pieces | Titanium and ceramic case, with a black carbon-patterned dial and red chronograph accents. |
| King Gold Ceramic | 250 pieces | King Gold and ceramic combination. |
| Red Magic | 100 pieces | Bright red ceramic case and carbon-patterned dial. |
| All Black | 500 pieces | Matte and polished black ceramic case with a black carbon-patterned dial. |
| Magic Gold | 100 pieces | Hublot’s 18-karat Magic Gold alloy, with a carbon-patterned dial and gilt hands and markers. |
These are quantities announced by Hublot, not a measure of present-day stock or resale value. Hublot describes Magic Gold as a scratch-resistant 18-karat alloy; that characterization is the manufacturer’s claim.
How the anniversary watches connect the 2005 design to Unico
Hublot dates the Big Bang’s launch to 2005. The design’s original proposition was material contrast: the brand describes combining steel or gold with fibreglass, rubber, and ceramic, alongside a dial patterned to evoke carbon weave. The 2025 watches revisit those visual cues while using the modern Unico movement platform.

Case and dial details
The shared case has a layered construction, pinched lugs, a knurled bezel edge, and rectangular pushers with rubber detailing. The dial replaces a simple printed carbon look with an engraved, carbon-fibre-inspired relief motif. Riveted Arabic numerals and indexes, filled with Super-LumiNova according to Hublot, sit alongside chronograph counters and red accents on selected versions.
Hublot says the anniversary models’ chequerboard-style dial treatment departs from the openworked presentation usually associated with Unico. The result puts the commemorative dial pattern in the foreground while retaining the chronograph layout.

Movement and strap
All five editions use Hublot’s Unico automatic flyback chronograph manufacture calibre and a commemorative gold rotor. On its anniversary collection page, Hublot describes Unico as an in-house automatic movement with 354 components and a 72-hour power reserve; it also says the flyback chronograph mechanism is positioned on the dial side in Unico models. These are manufacturer-published specifications, not independent measurements.
The structured rubber strap uses Hublot’s One Click changing system. The brand describes One Click as a patented mechanism integrated into the case, allowing the wearer to release and change the strap with a single click.

How to compare the five editions
- Start with the material and color: Titanium Ceramic is the mixed-metal option; King Gold Ceramic combines gold and ceramic; Red Magic and All Black make color the defining feature; Magic Gold uses Hublot’s proprietary gold alloy.
- Then consider the announced edition size: Red Magic and Magic Gold are each limited to 100 pieces, King Gold Ceramic to 250, and Titanium Ceramic and All Black to 500 each. Lower announced quantities indicate a smaller edition, not confirmed scarcity in the market or a prediction of future value.
- Do not expect a movement distinction: Hublot presents the Unico flyback chronograph and the principal anniversary case and dial features as shared across all five.
From the original Big Bang to the anniversary
Hublot’s own chronology places the Big Bang within a longer material story. The brand says its founding-era design language paired gold and rubber in 1980; it dates the first Big Bang All Black limited edition to 2006, Magic Gold’s announcement as an 18-karat alloy to 2011, and the unveiling of its first in-house-developed red ceramic to 2018. These dates and descriptions come from Hublot’s 2025 anniversary announcement and are best read as the manufacturer’s account of its design history.
For the anniversary, CEO Julien Tornare called the Big Bang “undoubtedly one of the modern icons of 21st century watchmaking.” He also said Hublot was looking both at what it had achieved through the collection and at its future potential. Those are the CEO’s views, quoted in Hublot’s 1 April 2025 announcement, rather than an independent consensus about the watch’s status.

What changed in the 2026 Big Bang Original Unico
On 19 January 2026, Hublot announced the Big Bang Original Unico as a return to the collection’s origins. It is a follow-on collection release, not a sixth anniversary edition. Hublot listed four versions at launch: Black Magic, Titanium, Titanium Ceramic, and King Gold Ceramic.
The brand says the Original Unico has a 43 mm case, sapphire caseback, refined edges and lugs, rubber-clad crown and pushers, a Unico calibre, and a newly shaped strap with One Click interchangeability. The launch continues the anniversary’s design conversation: a recognizable Big Bang form updated around the current movement and case execution.

Finding a specific anniversary model
For an exact reference to look up, Hublot’s product page identifies the Big Bang 20th Anniversary All Black 43 mm as reference 431.CI.1340.RX. Hublot lists a black ceramic case, HUB1280 Unico manufacture self-winding flyback chronograph, and approximately 72-hour power reserve for that model. These are product-page specifications; the page does not establish current retailer stock or price.
Use Hublot’s official product and boutique channels to identify the model, then assess any retailer listing separately. An indexed retailer result does not prove live availability. Check that a listing gives the same reference, identifies the seller, and provides clear authenticity and warranty information before relying on it.
