The Hublot Square Bang Unico 821.HX.0170.RX sits in Hublot's Square Bang family. It takes Hublot's bold sports-watch DNA and wraps it in a geometric square case instead of the usual round one. White ceramic and a black dial make it one of the most visually distinct pieces in the lineup.
This review covers what we know from handling the watch at our desk. We look at the specs, the case material, who asks for it, and what to check before you buy. Everything here comes from the watch itself, nothing else.

What the specs mean on the wrist
The case is white ceramic at 42mm. Ceramic resists scratches far better than steel or titanium. It also stays cool against the skin and does not discolor over time. The white finish creates a strong contrast against the deep black index dial. The movement is automatic, so daily wear keeps it wound. The rubber bracelet is a practical choice for a sports watch and easy to swap if you want a different look.
The condition is brand new. That means you get the full manufacturer packaging and no prior wear. The ceramic bezel matches the case, so the whole watch reads as one clean architectural object. There are no mixed materials to worry about aging at different rates.
The dealer’s take
At the desk, the Square Bang draws two kinds of buyers. The first already owns round Hublot pieces and wants something that looks nothing like them. The second is coming from a different brand and wants a square case done in serious materials. Both groups ask the same first question: how does ceramic hold up? The answer is simple. Ceramic resists surface scratches well, but it can chip on a hard corner impact, so ask us about that trade-off in person.
The white-on-black color pairing gets attention every time we put it on the counter. People ask whether the rubber bracelet looks too casual. It does not. Hublot designs the bracelet to work with the case, and on a square ceramic watch it reads as intentional, not sporty by accident. The brand-new condition means nothing has been adjusted or worn in, which matters for ceramic because you want to know the original finish is intact.
What to check before you buy a Square Bang Unico
- Ceramic surface condition: Even on a brand-new piece, inspect every edge and corner of the case under good light. Ceramic resists scratches but can chip. Confirm there are no chips before the watch leaves the counter.
- Full box and papers: A brand-new watch should come with all original packaging, hang tags, and a manufacturer warranty card. Verify the reference number on the documentation matches 821.HX.0170.RX exactly.
- Crown and pusher function: Work the crown through every position before you buy. Check that the automatic movement winds and sets correctly. If the watch has pushers, confirm they click and reset as they should.
- Bracelet and clasp: Check the rubber bracelet for any surface marks or deformation. The clasp should open and close with a firm, clean action. On a new piece, any stiffness is normal, but the mechanism should engage fully.
Who the 821.HX.0170.RX is for
This watch is for the buyer who wants a square case in a serious, scratch-resistant material and is comfortable standing out. It suits someone who already understands Hublot's design language or is ready to move away from conventional round sports watches entirely.

FAQ: 821.HX.0170.RX
What is the asking price for the Hublot Square Bang Unico 821.HX.0170.RX at Bizak & Co.?
The listed price at Bizak & Co. is $21,999. The watch is brand new. Contact us directly to discuss availability and any trade-in options.
Is 42mm a comfortable size for everyday wear?
The case measures 42mm. That fits most wrists as a substantial but wearable size. The square shape means the watch wears differently from a round 42mm, so we recommend trying it on if you can.
What type of movement does the 821.HX.0170.RX use?
The watch runs on an automatic movement. Daily wear keeps it wound without any manual winding. No additional movement specs beyond that are listed for this reference.
Is white ceramic a practical choice for a daily-wear watch?
White ceramic resists surface scratches very well and does not discolor over time. The trade-off is that ceramic can chip on a sharp impact at the case corners. For most daily use it holds up better than steel on surface marks, but it rewards careful handling.
