Presented on a rubber bracelet, this reference represents Hublot's Art of Fusion philosophy at its most dramatic — bold geometry, ultra-light materials, and a skeletonised tourbillon complication working in visual harmony.

What sets the 645.QG.5217.RX apart is the rare combination of a tonneau-shaped carbon fibre case, an eye-catching green index dial, and a manually finished tourbillon complication that elevates it well beyond a standard sports luxury watch.

The Hublot Spirit of Big Bang Tourbillon in reference 645.QG.5217.RX is one of the most visually commanding expressions in contemporary haute horlogerie. Where the original Big Bang redefined the round-case sports-luxury category, the Spirit of Big Bang pushes further still, adopting an elegant tonneau silhouette that pays homage to the golden era of case design while framing it in aggressively modern materials. At 42mm, this particular reference occupies a versatile sweet spot — substantial enough to command presence on the wrist, yet refined enough to wear with equal conviction alongside tailored suiting or relaxed weekend attire.

Carbon fibre is the defining material of this build, and Hublot's mastery of the substance is evident in every facet of the 645.QG.5217.RX. The case and bezel are both crafted in carbon fibre, yielding an exceptionally lightweight construction with the kind of structural rigidity that outperforms many metals. The woven texture of the carbon fibre catches light in constantly shifting patterns, ensuring the watch is never the same twice depending on viewing angle or illumination. This is not decorative carbon — it is integral to the watch's identity and engineering.

The green index dial is the colour story that ties the entire piece together. Against the dark, textured backdrop visible through the dial architecture, the vivid green indices create a chromatic tension that is at once sporty and luxurious. The skeletonised construction allows the eye to travel through the dial and engage directly with the tourbillon complication below — a cage rotating continuously to counteract the influence of gravity on the movement's precision. The result is a dial that functions as a stage for mechanical theatre.

The tourbillon complication positions the 645.QG.5217.RX firmly in the upper tier of Hublot's manufacture output. A tourbillon requires exceptional craft to produce and regulate, and wearing one is a statement of appreciation for traditional watchmaking elevated into the twenty-first century through Hublot's material innovation. The rubber bracelet — a Hublot signature since the original Big Bang — completes the watch with the brand's characteristic sporty sophistication, offering comfort and durability alongside the high-complication movement it carries.

Buying a Hublot Spirit of Big Bang Tourbillon 645.QG.5217.RX from Bizak & Co. means acquiring one of the watch world's most architecturally daring tourbillon references. Bizak & Co. specialises in sourcing and presenting exceptional timepieces at competitive prices, and our team of knowledgeable watch specialists is ready to assist with any questions about this reference, financing options, or shipping.

FAQ

1. What makes the Hublot Spirit of Big Bang Tourbillon 645.QG.5217.RX special?
The 645.QG.5217.RX combines Hublot's iconic tonneau-shaped Spirit of Big Bang case with a full carbon fibre construction — both case and bezel — and a tourbillon complication, all unified by a vivid green index dial. This trifecta of exceptional materials, avant-garde geometry, and a high complication makes it one of the most distinctive entries in the Spirit of Big Bang lineup. It is simultaneously a feat of modern material science and traditional haute horlogerie craft.

2. What movement powers the Hublot Spirit of Big Bang Tourbillon 645.QG.5217.RX?
This reference houses a tourbillon movement, a prestigious complication designed to neutralise the effect of gravity on the watch's regulating organ and thereby enhance long-term precision. The skeletonised architecture of the Spirit of Big Bang allows the tourbillon cage to be admired directly through the open dial. Hublot manufactures its tourbillon calibres in-house as part of its commitment to vertical integration.

3. What is the case size of the Hublot Spirit of Big Bang Tourbillon 645.QG.5217.RX?

The 42mm measurement makes it a versatile size suitable for a wide range of wrist sizes, sitting between Hublot's smaller and larger Spirit of Big Bang offerings. Despite the visual drama of the design, the lightweight carbon fibre construction keeps the watch feeling comfortable throughout the day.

4. Is the Hublot Spirit of Big Bang Tourbillon 645.QG.5217.RX suitable for everyday wear?
While this is an ultra-premium haute horlogerie timepiece housing a tourbillon, Hublot's use of carbon fibre and a rubber bracelet gives the 645.QG.5217.RX a robustness and lightness that many dress tourbillons cannot match. It transitions naturally from formal to casual settings and the durable materials are well-suited to active lifestyles. That said, as a tourbillon, it naturally deserves thoughtful care and periodic servicing by an authorised watchmaker.

5. What are the key materials and dial details of the 645.QG.5217.RX?
The case and bezel are both constructed from carbon fibre, a material prized for its extremely high strength-to-weight ratio and striking woven visual texture. The dial features green indices set against an open, skeletonised architecture that reveals the tourbillon movement beneath. A rubber bracelet — a hallmark of the Big Bang family — completes the build, reinforcing the watch's sporty yet luxurious character.
