Hublot announced two 42 mm Big Bang Unico Winter watches on 24 November 2025: the Winter Sapphire, limited to 30 pieces, and the Winter Titanium Ceramic, limited to 200. Their main difference is the case construction; both share the HUB1280 UNICO movement and One Click strap system. The available information is Hublot’s announcement, not a hands-on assessment, so it does not establish how either watch feels or performs on the wrist.
What separates the two Winter Editions?
The clearest distinction is material and scarcity. Hublot describes one model as a sapphire-cased watch and the other as a titanium-cased watch with a white ceramic bezel. Both measure 42 mm, but their production limits differ substantially.
| Model | Case and bezel | Size | Edition limit |
|---|---|---|---|
| Big Bang Unico Winter Sapphire | Sapphire case; bezel material not stated in Hublot’s announcement. | 42 mm | 30 pieces |
| Big Bang Unico Winter Titanium Ceramic | Titanium case with white ceramic bezel | 42 mm | 200 pieces |
The limits and dimensions above are manufacturer-announced specifications from 2025, not independently verified production or market figures. Hublot calls the titanium case “featherlight,” but the announcement gives no case weights or comparative measurements. It also does not support a durability ranking between the materials.
What movement do they use?
Both watches use Hublot’s HUB1280 UNICO movement. The brand describes it as an in-house movement with five patents and says its snowflake-shaped oscillating weight can be seen through the caseback. Hublot presents the snowflake as a seasonal design cue as well as a signature of the movement.

The announcement lists these movement mechanisms: dual oscillating horizontal clutches, an anti-trembling system, a zero-friction ratchet-wheel blocker, a constant-pressure minute-wheel friction system, and a balance-wheel fine-adjustment mechanism. These are manufacturer descriptions; the announcement does not provide independent testing or performance comparisons.
Straps and changing them
Each watch is supplied with two interchangeable rubber-lined calfskin straps, one white and one ice blue. Hublot says they attach using its One Click system. The announcement does not specify third-party strap compatibility, so check fit with Hublot or an authorized retailer before buying a replacement.

Availability, price, and what is not established
Hublot said the editions would be available at selected points of sale. Its 24 November 2025 announcement does not state a retail price, reference numbers, current inventory, or availability in a particular region. Contact Hublot or an authorized retailer for current stock, local pricing, and exact references; the limited-edition quantities alone do not establish demand or resale value.
Hublot CEO Julien Tornare framed the releases as a celebration of winter, referring to settings from Zermatt to Aspen. That is the brand’s promotional positioning, rather than an independent assessment of the watches.
