The Hublot Square Bang Unico Ceramic Magic Gold 42mm Chronograph 821.CM.0130.RX combines bold contemporary design with Hublot’s signature material innovation. The 42mm × 42mm square case is crafted from microblasted and polished black ceramic, giving the watch a lightweight yet durable structure. Its bezel is polished 18K Magic Gold, a proprietary scratch-resistant alloy of 24K gold fused with ceramic, secured by six H-shaped black-plated titanium screws.
The skeletonized sapphire crystal dial showcases the in-house HUB1280 UNICO Manufacture self-winding chronograph movement. This calibre features a flyback function and a visible column wheel on the dial side, composed of 354 components, providing both mechanical sophistication and visual depth. The movement offers an approximate 72-hour (3-day) power reserve. With water resistance rated to 100 meters (10 ATM) and a black structured rubber strap with black ceramic and black-plated titanium deployant buckle, the watch balances sportiness with luxury finishing.
