The Hublot Big Bang Original Unico Reinterprets A Modern Icon

Hublot continues the evolution of its most recognizable collection with the introduction of the Big Bang Original Unico, a model that revisits the core design principles of the Big Bang while incorporating updated proportions, refined ergonomics, and the brand’s in-house chronograph movement. Although the Big Bang marked its 20th anniversary in 2025, this release looks ahead, reinterpreting the original concept rather than serving as a commemorative edition.

Updated Case Proportions and Design

One of the most notable changes comes in the form of a newly sized 43 mm case, positioned between the 41 mm and 44 mm formats previously used across the Big Bang range. The case architecture has been subtly revised, with softened contours and more pronounced curvature in the lugs to improve comfort on the wrist. Transitions between brushed and polished surfaces have been refined, and a newly introduced beveled edge adds definition to the multi-layered case construction, lending the watch a more streamlined and cohesive appearance while preserving the unmistakable Big Bang identity. Water resistance is rated at 100 meters, aligning the Big Bang Original Unico with the expectations of a modern luxury sports chronograph.

Material Choices and Case Variants

Staying true to Hublot’s “Art of Fusion” philosophy, the Big Bang Original Unico is offered in four distinct material configurations, each highlighting a different aspect of the brand’s material expertise. The titanium version features a lightweight case with alternating satin and polished finishes, complemented by rubber-capped pushers and crown, and is priced at CHF 16,900.

The Black Magic variant is crafted entirely from black ceramic, offering enhanced scratch resistance and a monochromatic, technical aesthetic, and retails for CHF 18,900.

For those seeking contrast, the Titanium Ceramic reference pairs a titanium case with a black ceramic bezel, combining lightness with durability, and is priced at CHF 17,900.

At the top of the range sits the King Gold Ceramic model, which uses Hublot’s proprietary King Gold alloy for the case, again matched with a black ceramic bezel to enhance wear resistance and visual depth. This version retails for CHF 32,900.

Across all versions, the watches are fitted with Hublot’s integrated structured rubber strap, a defining element of the Big Bang collection.

The Unico Manufacture Chronograph Movement

Inside the Big Bang Original Unico beats the MHUB1280 Unico Manufacture caliber, an automatic flyback chronograph developed and produced in-house by Hublot. The movement is built around a column wheel and a dual-clutch architecture, ensuring precise chronograph operation and smooth engagement. It offers a power reserve of approximately 72 hours, allowing the watch to run for three days on a full wind. A skeletonized tungsten rotor is visible through the sapphire crystal caseback, offering a clear view of the movement’s architecture and reinforcing the watch’s technical character.

The openworked dial further emphasizes the mechanical nature of the watch, allowing glimpses of the chronograph components while maintaining legibility.

A Measured Evolution of the Big Bang

With the Big Bang Original Unico, Hublot delivers a refined interpretation of its flagship chronograph. The updates focus on proportions, ergonomics, and material execution rather than radical design changes, ensuring continuity within the collection while subtly modernizing its appearance. The result is a watch that remains instantly recognizable as a Big Bang, while benefiting from incremental technical and aesthetic enhancements.
