Hublot BIG BANG UNICO SKY BLUE 441.EX.5120.RX

42mmSuper Clone Watch

Original price was: $1,450.00.Current price is: $1,129.00.

This is the right pick if you want the Big Bang Unico look with real visual punch but without stepping up to the bulkier 45mm case. The deciding details are the solid sky blue ceramic case and bezel, the open-worked Unico-style dial with visible column wheel architecture, and the white-lined blue rubber strap with Hublot’s One-Click system. Compared with older steel-based colored versions, this watch stands out for its full ceramic construction and sharper case presence. The detailed description matters here because this reference lives or dies by execution.

Hublot

Sky blue ceramic is the whole point of this reference

The first thing that decides this watch is the color execution. On the 441.EX.5120.RX, the sky blue case and matching bezel are not a small accent against a standard sports watch shape; they are the identity of the piece. Here that matters because the case is specified as solid pigmented ceramic rather than color-coated steel, so the appeal is not only visual. You get the cooler feel of ceramic on the wrist, the scratch-resistant surface buyers expect from this style, and a color tone that makes sense across the case rather than reading like a surface treatment.

Just as important, the 42mm format keeps the Big Bang profile assertive without drifting into the sheer size of many 45mm examples. If you like the angular Hublot case, exposed H-screw bezel layout, and the layered architecture of the Unico line, but want a version that is easier to place into regular rotation, this is the more balanced size.

The dial gives you the mechanical theater buyers looking for from a Unico

This watch is visually driven from the dial side. The skeletonized layout opens up the movement architecture immediately, with the chronograph works and dial-side mechanical detail left in view instead of hidden under a solid face. The floating hour markers, broad hands, and blue chronograph register create enough contrast to keep the display readable, while the open central section gives the watch the technical look that makes the Unico family appealing in the first place.

The movement fitted here is the custom HUB1280 clone, built to present the dial-side column wheel in the way enthusiasts expect on this reference. That distinction matters. Earlier alternatives in this category often delivered the color and shape, but not the same mechanical layout from the front. If your eye goes straight to what is happening under the hands and around the counters, this version has a stronger reason to exist.

Why BBF matters on this specific watch

Factory names only matter when they solve a real problem, and on this reference they do. BBF’s advantage is tied directly to two things that are easy for an informed buyer to care about: the use of solid colored ceramic and the correct dial-side presentation of the Unico-style chronograph architecture. That makes this watch a more compelling choice than older colored versions that relied on steel with a coated finish or more generic chronograph foundations.

You are also getting a fully functional chronograph and date, supported by an approximate 36-hour power reserve. That gives this piece substance beyond color alone. It still wears like a statement sports chronograph, but one with enough mechanical interest to justify close inspection from the front and back.

The strap and caseback complete the character

The rubber strap suits the watch exactly as it should. From the front, it shows a structured blue upper surface with white side framing that ties into the bright case tone cleanly. The One-Click strap system is part of the appeal because this is a watch that works best when worn often and changed around easily, not treated as a static display piece. The visual contrast between the blue exterior and white underside keeps the watch feeling sharp and intentional rather than monochromatic.

Turn it over and the display back keeps the technical story going. The movement remains visible through the rear crystal, framed by the blue caseback surround and white rubber underside. It is the kind of detail that matters on a skeletonized chronograph: if the front of the watch invites inspection, the back should reward it as well.

Who should choose this one

This is the version to buy if you want a summer-weight color concept without giving up the aggressive, mechanical identity that makes the Big Bang Unico line interesting. The 42mm case is the practical argument, the ceramic construction is the quality argument, and the open-worked chronograph layout is the enthusiast argument. Put together, they make this one of the more convincing modern Hublot references for someone who wants color, structure, and visible movement design in the same watch.
