The Hublot Spirit of Big Bang Tourbillon Carbon White, ref. 645.QW.2012.RW, is a tonneau-shaped tourbillon watch. It sits above the standard Spirit of Big Bang line because it carries a hand-wound tourbillon movement. The carbon fibre case and bezel put it firmly in Hublot's high-performance, fusion-materials tier.
This review comes straight from the desk at Bizak and Co. We cover the case, the dial, the movement, and the ownership questions buyers ask us most. We stock this piece brand new, so every detail here is drawn from the watch in hand.

What the specs mean on the wrist
The case is 42mm and shaped like a tonneau, not a circle. That shape wears closer to the wrist than a round 42mm case would. Carbon fibre keeps the weight low, which you notice the moment you put it on. The bezel is carbon fibre too, so there is no metal rim adding visual bulk. The rubber strap continues that lightweight, sport-luxury feel on the wrist.
The movement is manual wind. You wind it by hand, which is a deliberate choice on a watch like this. A tourbillon is a rotating cage that holds the escapement. It fights the pull of gravity on the movement. On this dial, with its clean white index layout, the tourbillon is part of what you see, not hidden away.
The dealer’s take
Buyers who ask for this reference usually come in one of two ways. Some already know Spirit of Big Bang and want the tourbillon step-up. Others come from round Big Bang tourbillons and want the tonneau shape instead. The carbon-and-white combination draws a specific type of collector. They want the mechanical complexity but they also want something that reads modern, not dress-watch traditional.
The questions we hear most at the desk are about the tourbillon, the carbon construction, and the limited-edition status. People want to know what makes this carbon case different from a metal one. The answer is simple: it is lighter and it has a texture that catches light in a way metal does not. Because this is a limited edition, buyers also ask about availability. Our honest answer is always the same: when these are gone, you wait for the secondary market.
What to check before you buy a Spirit of Big Bang
- Confirm it is brand new and unworn: Ask for the full set: box, papers, hang tags, and any seals. A brand-new piece should have all of them. Check that the warranty card is blank and unstamped.
- Inspect the carbon fibre case and bezel: Carbon fibre can show micro-chips at the edges if a watch has been handled roughly. Look at the case flanks and bezel under good light before you accept delivery.
- Verify the tourbillon cage moves freely: Wind the watch a few turns and watch the tourbillon cage rotate. It should move smoothly and steadily. Any hesitation is worth flagging to the selling dealer before purchase.
- Check the rubber strap condition: On a brand-new piece the strap should show no creasing, cracking, or scent of storage. Rubber can degrade in poor storage conditions even before a watch is worn.
Who the 645.QW.2012.RW is for
This watch is for the collector who wants a hand-wound tourbillon in a lightweight, modern package. The tonneau shape and white dial give it a distinct look that separates it from round-case tourbillons. If you value mechanical craft and contemporary materials in equal measure, ref. 645.QW.2012.RW is built for that brief.
Alternatives worth considering
- Hublot Big Bang Tourbillon (round case references) — Shoppers cross-shop this when they prefer the classic round Big Bang shape over the tonneau.
- Hublot Spirit of Big Bang (non-tourbillon references) — A consideration for buyers who want the tonneau case at a lower complexity level.
