If you want the Square Bang in its sharpest colorway, this is the one to choose. The brushed King Gold-tone square case, deep blue skeleton dial, and matching textured blue rubber strap give it the high-contrast look that makes this reference stand out instantly. It also offers the Unico-style visual drama many collectors want, with the date ring and chronograph layout left open across the dial. Compared with a darker ceramic execution, this version is warmer, bolder, and far more architectural on the wrist, which is why the details below matter.

The blue and King Gold contrast is what makes this reference

The first thing that lands with the 821.OX.5180.RX is the way the brushed King Gold-tone square case frames the blue skeletonized display. That contrast is the whole point of this watch. The warm case tone gives the Square Bang its weight and presence visually, while the blue dial side and matching blue rubber strap keep it contemporary rather than dressy. If you are considering this model over a darker ceramic version, this is the execution that feels more expressive and more obviously architectural from across the room.

The 42mm square case keeps the profile assertive without losing the compact, integrated look that makes the Square Bang different from a conventional round chronograph. The black side inserts and exposed bezel screws add the industrial edge buyers expect from this design, and the brushed top surfaces help the case read cleanly instead of flashy.

An openworked dial that puts the chronograph display front and center

This watch is all about dial depth. Instead of a closed dial, you get a layered blue skeleton layout with exposed gearing, a visible outer-style date track, and two prominent blue subdials. The chronograph register at 3 o’clock is easy to pick out thanks to its bold blue ring and warm-toned numerals, while the running seconds at 9 o’clock balances the display and adds even more movement to the dial side.

Rose-toned applied markers and broad matching hands keep the watch readable despite the amount of visual information on display. That matters on a watch like this. A fully openworked layout can easily become messy, but here the strong hour markers, distinct subdial rings, and square case aperture create structure. You are buying this reference for spectacle, but it still needs to tell the time at a glance, and this one does.

Clone HUB1280 automatic movement and the appeal of the Unico layout

Inside is a Clone HUB1280 automatic movement with hours, minutes, sub-seconds, date, and chronograph functions. For the buyer who specifically wants the Square Bang because of its mechanical theater, that movement choice matters. The watch is built around the Unico-style idea of showing more of the mechanism from the dial side rather than hiding it behind a traditional face.

The visible date ring and open dial construction are a major part of the ownership appeal. This is not the watch for someone who wants a restrained sports model. It is for someone who wants the mechanics to be part of the design every time the wrist turns. That is why this reference works best for collectors who appreciate modern skeleton chronographs rather than classic three-hand pieces.

Sapphire crystal, textured rubber strap, and quick-release practicality

The crystal is sapphire with anti-reflective treatment, which suits a watch with this much dial depth. You want to be able to look into the layers of the display without constant glare getting in the way. On a skeleton chronograph, crystal quality affects the experience more than many buyers expect, because the watch is meant to be viewed from angles, not just straight on.

The blue rubber strap is another strong point. Its textured grid pattern ties directly into the modern Hublot design language and keeps the watch planted in the sports category even with the gold-tone case. The clasp shown is a deployant style, and the strap integrates cleanly into the case so the watch keeps its square, continuous silhouette. The one-button quick-release system is also part of the appeal for anyone who values easy strap changes without turning the watch into a project.

Why this 821.OX.5180.RX is the Square Bang to buy

Some watches are about restraint. This one is about shape, contrast, and mechanical visibility. The appeal of the 821.OX.5180.RX is that every major element is working toward the same result: the square brushed King Gold-tone case gives it structure, the blue skeleton dial gives it depth, and the matching blue rubber strap keeps it modern and wearable. Nothing here feels accidental.

If you already know the Square Bang line and want the version with the strongest visual separation between case, dial, and strap, this reference makes a very convincing case for itself. It is especially appealing for collectors who want an openworked automatic chronograph with a distinct case architecture rather than just another round skeleton sports watch.
