The Hublot Big Bang Unico 421.NX.1170.RX.1104 is one of the most compelling expressions of the Big Bang collection, uniting the raw, technical character of a 44mm titanium case with the undeniable glamour of a fully diamond-set bezel. Introduced as the flagship line within Hublot's catalog, the Big Bang has been a defining force in contemporary haute horlogerie since its debut, blending unconventional materials with Swiss mechanical excellence in a way that few brands have dared to attempt.

At 44mm, the Big Bang Unico commands attention on the wrist without crossing into unwearable territory. Titanium — chosen for its exceptional strength-to-weight ratio — gives this reference a featherlight feel that belies its bold, muscular proportions. The H-shaped titanium screws on the bezel, an iconic Big Bang design signature, contrast beautifully with the diamond setting, reinforcing Hublot's philosophy of the Art of Fusion.

The black dial of reference 421.NX.1170.RX.1104 is a masterclass in legibility and drama. A mix of index hour markers and Arabic numerals populates the dial, while the skeletonized movement architecture allows glimpses of the mechanical heart beating beneath. The sub-dials for the chronograph functions are precisely integrated, and the overall layout remains easy to read despite the complexity underneath.

Powering this watch is Hublot's celebrated in-house Unico movement, an automatic flyback chronograph caliber developed entirely within the Hublot manufacture. The flyback complication allows the chronograph to be reset and restarted with a single push of a button — a feature prized by pilots, athletes, and enthusiasts who demand timing precision without interruption. The movement is visible through the exhibition caseback, offering a direct connection to the watchmaking craft within.

The black rubber strap completes the sports-luxury aesthetic perfectly, providing comfort and durability whether worn to a boardroom or poolside. It pairs seamlessly with the titanium case hardware, and the deployant clasp ensures secure, easy adjustment. For collectors seeking a watch that performs as convincingly in casual settings as it does at formal occasions, the Big Bang Unico titanium diamonds strikes an ideal balance.

Bizak & Co. is proud to offer this reference 421.NX.1170.RX.1104 brand new, complete with full manufacturer box and papers, at the best available price. Our team of specialists is on hand to answer any questions, assist with sizing, and ensure your purchase is seamless from first inquiry to delivery. Reach out to Bizak & Co. today and secure this exceptional Hublot Big Bang Unico for your collection.
