Hublot Big Bang Original Unico Coal Blue Titanium 43mm 431.NX.717B.RX

The Hublot Big Bang Original Unico 431.NX.717B.RX is one of the most visually commanding expressions of the Big Bang family, presenting a 43mm titanium case wrapped in a deep coal blue personality that distinguishes it from more conventional sporty references. Since its debut in 2005, the Big Bang has redefined what a contemporary luxury sports watch can look like — aggressively architectural, materially sophisticated, and unmistakably Hublot. This particular reference, finished in titanium with a coal blue dial, captures that spirit at its most wearable and refined.

The 43mm titanium case of the 431.NX.717B.RX is engineered for both lightness and toughness, making it an ideal daily companion for the active collector. Titanium offers exceptional strength-to-weight ratio, meaning the watch sits comfortably on the wrist for extended wear without the density of steel or precious metal alternatives. The case architecture stays true to the signature Big Bang design language: bold multi-part construction, exposed screws at the bezel, and pronounced lugs that command wrist presence without becoming unwieldy.

At the heart of the dial, the coal blue finish creates a rich, layered depth that shifts between slate and midnight depending on the light source. Index and Arabic numeral markers are distributed across the dial with purposeful clarity, providing legibility that matches the watch's sporty intent. The combination of a titanium bezel and the blue dial creates a tonal harmony that feels both restrained and luxurious — a balance Hublot executes with particular confidence in this reference.

Powering the 431.NX.717B.RX is Hublot's automatic Unico movement, the in-house caliber that elevated the Big Bang Original to a new tier of horological credibility. The Unico is visible through the exhibition caseback, offering collectors a direct view of Hublot's integrated column-wheel flyback chronograph architecture — a movement developed and manufactured entirely within the Hublot manufacture in Nyon, Switzerland. It represents the brand's most significant statement in movement mastery and is a key reason why this generation of Big Bang commands serious collector attention.

The black rubber strap completes the package with Hublot's signature fusion philosophy, pairing high-tech materials with luxurious finishing. Rubber straps on Hublot watches are not afterthoughts — they are engineered for comfort, durability, and a precise fit, and they reinforce the sporty-luxury duality the Big Bang has always embodied. Swapping straps is straightforward with Hublot's one-click system, giving owners the flexibility to customize their wearing experience.
