Hublot Square Bang Unico: Specs, References, and Pricing | Ultimate Watch

The Square Bang Unico is what happens when Hublot takes the Big Bang, its signature round chronograph since 2005, and forces it into a square case without losing a single design cue collectors recognize. Hublot introduced it in April 2022 at Watches and Wonders in Geneva, and it was the first genuinely new case shape from the Maison in years. The case runs 42mm across the flats with a thickness of 14.5mm, water resistant to 100 meters, which is a real engineering flag: a square case is much harder to seal than a round one because you are managing four corners and four straight gaskets instead of one continuous circle. Under the sapphire crystal dial sits the in-house HUB1280 UNICO caliber, a self-winding flyback chronograph with a column wheel and 354 components. Every hard signature is intact: the six functional H-shaped screws around the bezel, the sandwich case construction, the rubber-clad crown and pushers, the exposed movement. We buy and sell these across ceramic, titanium, and King Gold at our counter on 47th Street, and the Square Bang has settled into a clear pattern on the secondary market that is worth understanding before you buy one new. If you have one to sell or you want us to source a specific reference, bring it in or call the shop.
