Buying notes for this configuration
The right moment for this Spirit of Big Bang is when a black dial needs a deliberate flash of color. Its blue strap pulls the eye away from a purely case-led reading and gives the tonneau profile a cleaner visual rhythm. A rounder 42mm Big Bang Unico on a black strap is the useful alternative: that version is easier to keep neutral, while this one is more memorable because the blue is confirmed and visible from the first gallery frame. The choice is therefore about how much color should remain present after the dial has done its work.
The Hublot Spirit of Big Bang 642.OX.7180.RX earns its place through contrast: a warm-toned angular case, a black openworked chronograph face, and a blue structured rubber strap confirmed for this listing. The blue strap changes the watch from a conventional dark sports configuration into a sharper color-led choice. At 42mm, the case keeps that contrast focused rather than oversized. Buyers choosing this reference should want the strap color to remain part of the watch’s identity, not an afterthought.

Blue is the reason to notice it
The first view should be read as a relationship between the dark openworked dial and the blue strap. The strap does not merely finish the case; it gives the angular Spirit of Big Bang a second visual axis. That matters for a buyer who wants a skeleton chronograph presentation without defaulting to an all-black wrist profile. The warm-toned case supplies the contrast in the center, while blue keeps the composition from becoming visually flat.
How the 42mm profile wears
At 42mm, this is a statement in shape rather than scale. The case architecture announces itself through its curved, tonneau-like outline, but the measured diameter keeps the blue-and-black palette from overwhelming the wrist. The angled images are important because they show how the bezel, case edges, and strap join one another. Select it for a smart-casual setting where the watch can be seen from the side as well as straight on.
The nearby choice is quieter
A black-strap round Big Bang Unico is the closest practical comparison. It suits a buyer who wants the dial and bezel to carry the entire conversation. This reference answers a different brief: the strap should repeat the buyer's preference for controlled color. That distinction is more useful than comparing model names alone, especially when two watches can share an openworked sports vocabulary but create very different first impressions.
What to read in the dial
Look for clean separation between the hands, registers, and the skeletonized architecture. The bezel screws should sit evenly around the case, and the pusher geometry should look intentional from the front and three-quarter views. The blue strap should remain a consistent visual match across the gallery, with no distracting mismatch between its color and the case-side finish. These are the details that make a graphic configuration feel composed.
QC for the blue-strap version
Verify the blue strap color against the final gallery, then inspect case symmetry, the six bezel screws, dial and register alignment, pusher fit, and strap-to-case fit. The inspection should use the front, angled, and strap views together, because this reference is defined by how those parts agree as one visible arrangement.
