Original price was: $1,600.00.Current price is: $1,280.00.

If you want the loudest Big Bang Unico in this size, this is the one to buy. The rainbow baguette bezel, gem-set case, and openworked Unico-style dial give it the full visual impact, while the flyback chronograph and skeletonized date keep it interesting once the novelty wears off. Compared with simpler rainbow executions, this BBF version stands out for pairing the exposed HUB1280-style layout with a display back. The detailed description matters here because the strap and visible finishing differ from the usual expectation for this reference family.

Rainbow bezel first, then the rest of the watch catches up

The deciding feature here is the way the rainbow setting is handled across the entire front of the watch. You get a bezel set with rectangular multicolor stones, then a second ring of smaller stones inside it, followed by a gem-set upper case section that carries the color gradient onto the lugs. That layered approach gives this 42mm Big Bang Unico a denser, more deliberate look than versions that stop at the bezel. On the wrist, it reads as a full jewelry-sport watch rather than a standard chronograph with a colorful insert.

The case is finished in king-gold-tone plating over 316L steel, with the familiar H-shaped screws and broad, angular Big Bang architecture. That matters because the geometry is what keeps a watch this decorative from becoming soft. The hard edges, exposed screws, and dark composite side sections still give it the industrial stance collectors expect from a Unico.

The dial keeps the watch technical, not just flashy

This piece uses an openworked dial with the mechanics left in view, and that is important for this model. A rainbow Big Bang only works when there is still enough visual contrast in the center to remind you it is a Hublot chronograph, not just a gem-set case. Here, the black and grey movement-side background, applied rose-gold-tone markers, and skeletonized date ring give the face real depth.

The subdials are clearly laid out, with the running seconds at 9 and the 60-minute chronograph register at 3. The central chronograph hand and broad main hands remain easy to pick out against the busy dial, and the hands show luminous fill for low-light legibility. If you are comparing this with a closed-dial rainbow variant, that open display is one of the strongest reasons to choose this reference style: it gives you much more to look at once the watch is on your wrist.

Why the BBF execution is the right fit for this reference

This model is offered with a custom HUB1280 flyback chronograph featuring a working horizontal clutch and approximately 48 hours of power reserve. For a buyer who knows the Unico line, that is the technical point worth caring about. The appeal is not just that the watch looks right through the dial side; it is that the movement architecture is chosen to support the visible layout and the chronograph function this model is supposed to deliver.

There is also a practical reason this version makes sense against simpler alternatives. Many rainbow watches deliver the stones but lose some of the mechanical theater. This one keeps the openworked date display, visible chronograph layout, and sapphire display back, so the watch still feels like a Unico first and a gemstone piece second. That balance is what makes it easier to justify if you already own more restrained chronographs and want this one to occupy a clearly different place in the collection.

Strap, caseback, and wear profile

The strap shown here is a black rubber-backed strap with a colored upper surface rather than a plain black band. That changes the character of the watch more than you might expect. A plain strap would visually isolate the case; the colored top keeps the rainbow theme running past the lugs and makes the whole watch feel intentional. From the rear, the display back reveals the movement side, with BBF marking visible on the caseback sticker and engraved Big Bang text around the perimeter.

Scratch-proof sapphire with anti-reflective coating helps because this dial has a lot happening underneath the crystal. Without decent clarity, an openworked chronograph can look muddled. Here, the crystal is part of why the layered dial, date ring, and subdial framing remain readable enough to enjoy. Water resistance is offered as splash and rain proof for daily cautionary use, which is the sensible way to treat a complex chronograph like this.

For the buyer who already understands what a Big Bang Unico should feel like, this watch succeeds because it combines three things that do not always come together in one piece: a properly aggressive 42mm case shape, a genuinely dramatic rainbow setting, and a visible flyback chronograph layout that keeps the watch mechanically interesting every time you pick it up.

Buyer Q&A

Questions about this Hublot watch

What makes this rainbow version different from a standard Big Bang Unico?

The watch combines a rainbow baguette-set bezel, additional gem-setting on the upper case, an openworked dial, and a skeletonized date display. That gives it a much fuller jewelry-sport look than a standard Unico with a plain bezel.

Does this watch have a display back?

Yes. The rear sapphire caseback shows the movement, rotor, and internal chronograph-side architecture from the back of the watch.

What chronograph layout is visible on the dial?

The dial shows a running seconds register at 9, a 60-minute chronograph register at 3, a central chronograph hand, and a visible date display integrated into the openworked layout.
