Hublot marks a significant evolution in its iconic Big Bang series with the introduction of four new Big Bang Original Unico models. These timepieces, equipped with the brand's proprietary chronograph movement, continue the "Art of Fusion" philosophy established by Carlo Crocco in 1980 and dramatically amplified by Jean-Claude Biver's visionary leadership. This latest collection builds upon the success of the 20th-anniversary editions, offering a non-limited range that embodies Hublot's innovative spirit and mastery of diverse materials.

The new Big Bang Original Unico collection retains many of the distinctive design elements that have defined the series since its inception in 2005. Key features include the intricate multi-layered case construction, the uniquely textured bezel edge, and the rectangular pushers accented with rubber. The bezel is secured by six functional, distinctively placed screws, while lateral protective elements, often referred to as 'ears,' further enhance its robust aesthetic. A hallmark of these models is the mandatory integration of various materials, showcasing Hublot's two-decade commitment to material innovation. All four models share a consistent case size of 43mm in diameter and 13.2mm in thickness, mirroring the specifications of the recent anniversary releases.

The collection introduces a diverse array of material combinations, catering to different preferences while highlighting Hublot's technical prowess. The 'Black Magic' variant features an entirely black ceramic case, a material renowned for its resilience and first introduced by Hublot in 2006. Alongside this, a model combining titanium and black ceramic offers a sophisticated contrast. For those seeking a more luxurious appeal, an eye-catching King Gold and ceramic version is available, utilizing Hublot's exclusive King Gold alloy—a warmer, redder gold fortified with platinum for enhanced hardness. Completing the quartet is a lightweight full-titanium model, emphasizing comfort and durability.

Echoing the design ethos of the original 2005 Big Bang watches, the dials of these new models feature a two-tone checkered pattern, reminiscent of carbon fiber textures. However, a notable departure from the early designs is the adoption of a two-counter layout, similar to the anniversary editions, moving away from the traditional three-counter configuration. This revised layout places a small seconds sub-dial at 9 o'clock and a larger, snailed 60-minute chronograph register at 3 o'clock. The riveted Arabic numerals and indices, while classic, are now enhanced with Super-LumiNova for improved legibility, and the date window maintains its familiar position at 4:30.

At the heart of these chronographs is Hublot’s in-house automatic Unico movement, calibre HUB1280, first launched in 2010. This sophisticated integrated flyback chronograph boasts a column wheel and a dual-clutch architecture, operating at a frequency of 4Hz and offering an impressive 72-hour power reserve. The intricate mechanics of the movement, including its openworked anthracite-colored tungsten rotor, are visible through the sapphire crystal caseback, allowing enthusiasts to admire Hublot's meticulous craftsmanship.

Practicality is also a key consideration, with the Big Bang Unico's 'One-Click' strap-change system enabling effortless customization. The black structured rubber strap, adorned with a lozenge pattern, can be easily swapped, enhancing the watch's versatility. Pricing for these new models varies based on the materials used: the Titanium version is available for CHF 16,900, the Black Magic for CHF 18,900, the Titanium Ceramic for CHF 17,900, and the King Gold for CHF 32,900. These additions represent Hublot's ongoing commitment to pushing boundaries in both design and horological engineering, offering a compelling blend of heritage and modernity to watch aficionados.
