The Hublot Big Bang Original is widely regarded as the watch that redefined the luxury sport category when it was introduced. Built around the concept Hublot calls the Art of Fusion – the deliberate marriage of contrasting materials, eras, and aesthetics – the Big Bang fuses precious metals, advanced ceramics, elastomer rubber, and high-grade alloys into a single cohesive design statement. Reference 431.NM.1370.RX is a particularly compelling expression of that philosophy, pairing a satin-polished titanium case with a scratch-resistant ceramic bezel and crown guards to create a watch that is simultaneously technical and elegant.

At 43mm in diameter, the Big Bang Original occupies what many collectors consider the sweet spot of the family. The case is large enough to command attention on the wrist yet stops short of the oversized proportions that can feel unwieldy in daily wear. The multi-part case architecture – with its exposed six H-shaped titanium screws on the bezel, integrated lug system, and layered case flanks – gives the 431.NM.1370.RX a distinctly three-dimensional appearance that photographs cannot fully capture until you see it in person.

The black dial of reference 431.NM.1370.RX strikes an ideal balance between legibility and luxury. Index hour markers and Arabic numerals work together to ensure instant readability while reinforcing the watch's sporting pedigree. Applied luminous markers and hands provide low-light performance, and the overall layout reflects Hublot's commitment to purposeful design rather than decoration for its own sake.

Powering the Big Bang Original is an automatic movement consistent with Hublot's long-standing commitment to in-house and manufacture-level calibers. The movement delivers reliable, self-winding performance appropriate for an active lifestyle. The rubber strap – an element Hublot pioneered in pairing with precious and technical-material cases – reinforces both the comfort and the sporty character of the reference, and can be swapped via Hublot's One Click system should the owner wish to explore different strap options.

From an investment and collector standpoint, the Big Bang Original in titanium and ceramic occupies an important position in the modern luxury watch market. Titanium's exceptional strength-to-weight ratio means the watch wears noticeably lighter than a comparably sized steel or gold piece, while the ceramic bezel resists everyday scratches and retains its deep, matte appearance over time. These are not merely cosmetic choices – they reflect genuine material science applied to wearable horology.

Our team of knowledgeable specialists is available to answer any questions, confirm current pricing, and assist with secure shipping anywhere in the United States.
