Introduction
The Hublot Square Bang is the latest evolution of the brand’s iconic Big Bang family, trading the round case for a sharp, angular silhouette. Launched in 2023, it immediately polarized collectors: some praised the daring geometry, others questioned whether a square watch could match the Big Bang’s wrist presence. After a full week of wear—commuting, gym sessions, dinner parties, and a weekend hike—I’m ready to answer the only question that matters: how does it actually feel on the wrist?
Hublot calls this ‘the art of fusion,’ and the Square Bang lives up to that mantra. The case is a sandwich of titanium, ceramic, and rubber, with the signature H-shaped screws holding it together. At 42mm, it’s not small, but the square shape changes everything about how it wears. The lug-to-lug is surprisingly manageable, and the integrated rubber strap wraps the wrist without the usual ‘square watch’ awkwardness. This is a watch that demands attention, but it also earns its keep as a daily companion.
Manufacture History
Hublot was founded in 1980 by Carlo Crocco, who introduced the first watch with a natural rubber strap—a revolutionary concept at the time. The brand remained relatively niche until Jean-Claude Biver took over in 2004 and launched the Big Bang in 2005. That model became a phenomenon, blending a porthole-inspired case with bold materials. The Square Bang, released nearly two decades later, is a natural progression: it keeps the Big Bang’s DNA but reimagines it in a square format. Hublot continues to push boundaries, and the Square Bang is proof that the brand isn’t afraid to experiment.
Movement
Inside the Square Bang beats the HUB1280, Hublot’s in-house automatic chronograph caliber. It’s a column-wheel movement with a vertical clutch, offering smooth start/stop of the chronograph hand. The power reserve is a generous 72 hours, and the frequency is 28,800 vph (4 Hz). The movement is visible through a sapphire caseback, where you’ll see a skeletonized rotor and Côtes de Genève decoration. It’s not haute horlogerie finishing, but it’s clean and industrial—fitting for a modern sports watch. Accuracy is excellent, as noted in the accuracy section.

Wrist Feel
The Square Bang is surprisingly comfortable for a 42mm square watch. The key is the lug-to-lug of 50mm—shorter than many round watches of similar diameter—and the curved rubber strap that hugs the wrist. The titanium case keeps weight down to about 120 grams, so it never feels like a brick. The deployant clasp is well-finished and adjusts easily, though the rubber strap can trap sweat in hot weather.
Where the Square Bang shines is balance. The square case sits flat against the wrist, with no top-heavy wobble. The crown and pushers are positioned at 2 and 4 o’clock, so they don’t dig into the hand. After a full day, I forgot I was wearing a square watch—until I caught a reflection and remembered how cool it looks.
Accuracy
Over a week of mixed wear, the HUB1280 ran consistently at +3 to +5 seconds per day. That’s well within COSC territory, even though Hublot doesn’t certify it. The 72-hour power reserve is generous; I left it off over a weekend and it was still running Monday morning. No complaints here.
Occasions
The Square Bang is versatile enough for daily wear, sporty enough for the gym (though I’d swap the strap for a rubber one with a pin buckle for workouts), and bold enough for a night out. It’s not a dress watch—the thickness and square shape won’t slide under a tailored cuff—but it works with casual and smart-casual attire. I wore it with a linen shirt and jeans, and it felt right at home.
Wrist Presence
4/5. The Square Bang is impossible to ignore. The faceted case, exposed screws, and bold dial create a visual punch that’s pure Hublot. It’s not subtle, but it’s not obnoxious either—just confident. On a 7-inch wrist, it wears like a 44mm round watch, so smaller wrists may find it overwhelming.
Reference Variants
The Square Bang is available in several materials: titanium (the lightest), ceramic (scratch-resistant but heavier), and King Gold (18K gold alloy). Dial options include black sunburst, matte black, and chocolate brown. Each variant comes with a matching rubber strap and deployant clasp. Limited editions have also been released, but the core trio covers most tastes.
Family References
The Square Bang sits alongside the round Big Bang Unico (42mm and 45mm) and the Big Bang Integrated (with a metal bracelet). It’s a distinct line, but shares the same movement and design philosophy.
Other Notable Hublot Models
If the Square Bang isn’t your style, consider the Big Bang Unico (round case, same movement), the Classic Fusion (slimmer, more understated), or the Spirit of Big Bang (tonneau case).
Similar Watches
Square chronographs are rare, but the Tag Heuer Monaco is the most famous rival. The Bell & Ross BR 03 offers a more tool-watch vibe at a lower price. The Cartier Santos is a dressier square option, though it lacks a chronograph.
Homages
For a fraction of the price, the Pagani Design PD-1701 offers a square chronograph with a Seiko mecha-quartz movement. It’s not in the same league, but it scratches the itch for under $100.
Investment Value
With an MSRP of $25,000, the Square Bang is a significant investment. However, Hublot watches typically depreciate on the secondary market. Pre-owned examples can be found for $18,000–$22,000. This is not a watch to buy for appreciation; buy it because you love the design and the wearing experience. Auction history is minimal due to the model’s recent release.
Service Interval
Hublot recommends a service every 5 years. The cost is approximately $800, and it must be done by an authorized service center. Turnaround is usually 4–6 weeks.
Pros and Cons
Pros: Unique square design with excellent wrist comfort; in-house Unico chronograph movement with 72-hour power reserve; lightweight titanium case and integrated rubber strap.
Cons: High retail price with steep depreciation; thick case (14.5mm) may not slide under a dress cuff; lume is adequate but not industry-leading.
Final Verdict
The Hublot Square Bang is a successful experiment in geometry. It wears better than most square watches, thanks to thoughtful lug design and a supple rubber strap. The in-house movement is a workhorse, and the bold aesthetic is unmistakably Hublot. If you can stomach the price and depreciation, it’s a genuinely fun watch to wear every day.
