The Hublot Big Bang Unico Summer 2025

Hublot has a new Summer 2025 limited edition of the Big Bang Unico, and its orange case and sky blue bezel capture the theme perfectly. The collection is known for high-tech ceramic cases fused with interesting colours, such as orange and dark green, although more muted colours like Mint Green and Petrol Blue offer an understated vibe (not that the Big Bang can be considered understated). Although this new colour palette evokes the summer evening’s golden hour and blue water, it does have a close resemblance to Gulf Oil’s iconic racing colours (not that we’re complaining).

The overall design is classic Big Bang Unico, but new colours can make all the difference, and this offers a more interesting summer theme than the Sky Blue model from 2023. The case is 42mm in diameter and 14.5mm in height, so bold without being overbearing. It’s high-tech, micro-blasted ceramic with a deep orange hue, while the ceramic bezel with six H-shaped titanium screws is sky blue, flanked by two dark blue case extensions with two screws (each) that match the dial’s main plate.

A sapphire crystal protects the dial, while a sapphire exhibition case back displays the in-house automatic. Both sapphire crystals have anti-reflective coatings. Water resistance is rated at 100 metres. There are the usual twin chronograph pushers at 2 and 4 o’clock and a large crown at 3 o’clock. Three rubber straps with a titanium deployant clasp come standard – orange, dark blue and sky blue (all with a white lining). Hublot’s patented One-Click strap system also allows for quick changes.

The dial is skeletonised with Arabic numerals and indices mounted over the visible date wheel. These numerals, indices and partially skeletonised hour/minute and sub-dial hands have white Super-LumiNova inserts. The central chrono seconds hand is yellow. The dial-side movement main plate, bridges and date wheel are dark blue, while the 60-minute sub-dial at 3 o’clock is sky blue. Of course, there must be some orange present, and the perimeter minute/chrono seconds track, small seconds, and 60-minute counter frames are all case-matching orange. A date window sits within the sub-dial at 3 o’clock. In classic Hublot style, the dial is loud and intricate in the best possible way.

Powering this Big Bang Unico is the HUB1280 Unico Manufacture flyback column wheel chronograph, first launched in 2018 (update to the original from 2010). The column wheel is clearly visible on the dial side at 6 o’clock. This 354-piece movement has 43 jewels, beats at 28,800vph (4Hz) and comes with a 72-hour power reserve, and also features a silicon escapement. Functions include central hours, minutes and flyback chronograph seconds, small seconds at 9 o’clock, 60-minute counter at 3 o’clock and date. The flyback function allows the chronograph to be stopped, reset and restarted with one press of the 4 o’clock pusher. Seen from the exhibition case back, the movement and rotor are finished in dark blue, creating a rear colour combination of this dark blue centre, sky blue outer case back secured via six screws against the orange main case.

The Hublot Big Bang Unico Summer 2025 retails for CHF 28,500, EUR 32,600, USD 31,300 or GBP 26,900 and is limited to 100 pieces.
