How to spot a
fake Hublot
Hublot built its identity on one instantly recognisable detail: the ring of H-shaped screws around a Big Bang or Classic Fusion bezel. That signature is exactly what counterfeiters cannot get right. Get the screws and the movement right and you have answered the authenticity question before you ever look at anything else. This guide leads with that single sharpest tell, then walks through the dial, the ceramic, the serial number and where to buy safely.
The one tell that matters most
Look at the six H-shaped screws on the bezel. On a genuine Hublot each screw is deeply and crisply machined into a clean, symmetrical H, mirror-polished, with no burrs. Crucially, they are not rotated to line up — Hublot deliberately leaves them at random orientations. Then flip to the movement: a Big Bang Unico shows a real in-house UNICO skeleton chronograph with open bridges and a visible column wheel. Fakes botch the H-shape, neatly align the screws to "look tidy," and hide a clone or printed dummy movement with no genuine skeleton finishing. Get those two right and the rest is confirmation.
The bezel screws: Hublot's hardest detail to fake
The Big Bang case is a multi-layer "sandwich" held together by twelve exposed screws, six of which are the signature H-heads visible on the bezel. Counterfeiters can reproduce the round outline of a Hublot in a photo, but replicating six precisely cut, mirror-polished H-slots is expensive and slow, so they cut corners. Watch for three things: the crispness of the H itself, the polish and depth of the cut, and the orientation. A genuine bezel looks intentionally irregular — the H-heads point every which way. A fake often has shallow, soft screw heads that are all rotated to the same tidy angle, which real Hublots never do.
Genuine Hublot H-screws are deep, mirror-cut and deliberately unaligned. Perfectly matched, shallow screws are a replica tell.
The UNICO skeleton movement fakes can't reproduce
On higher pieces — the Big Bang Unico line above all — Hublot fits its in-house UNICO automatic flyback chronograph. The current caliber, the HUB1280 (Unico 2), is a column-wheel chronograph with roughly a 72-hour power reserve and a genuinely skeletonised architecture, and one of its signatures is that the column wheel is visible from the dial side. Through the sapphire dial or case back you should see real depth: open bridges, machined bevels, a moving rotor, and mechanical parts that clearly sit on different planes. A fake usually hides either a cheap clone automatic or, worse, a flat printed graphic pretending to be a skeleton — no true openwork, no depth, no functioning column wheel. Note that not every Hublot is UNICO-powered, so confirm the caliber matches the specific reference.
A genuine UNICO shows layered, openworked mechanics and a working column wheel; a fake looks flat and printed with no real depth.
Six checks that confirm a genuine Hublot
1 · The six H-screws
Deep, symmetrical, mirror-polished H-heads at random orientations. Shallow, mushy, or perfectly aligned screws are the fastest replica tell on the whole watch. Check under magnification if you can.
2 · The movement
On a Unico, expect the in-house UNICO (HUB1280) skeleton chronograph with a visible column wheel and real layered depth. On simpler models, confirm the correct HUB caliber for that reference rather than assuming in-house.
3 · Material heft
The "Art of Fusion" means ceramic, titanium, King Gold, carbon or sapphire. Each has a distinct weight and feel — dense gold, hard scratch-proof ceramic, rigid-but-light titanium. Fakes in coated resin or cheap alloy feel warm, light, or hollow.
4 · Dial & logo printing
The applied "HUBLOT" wordmark and dial text should be razor-sharp with no bleed, fuzz, or uneven spacing. Applied indices and the "Ø" logo should be cleanly finished. Blurry or thick printing under a loupe points to a fake.
5 · Rubber strap & clasp
Genuine natural-rubber straps are supple with an even, distinctive lined texture and integrate precisely into the case lugs. The deployant clasp is solid and clicks cleanly. Stiff, plasticky, or smelly straps with rough edges signal a replica.
6 · Serial & paperwork
A deep, sharp 6–7 digit serial on the case back must match the raised serial on the warranty card. Post-2020 pieces carry Hublot's e-warranty. Verify with an authorised dealer; any watch-to-card mismatch is a deal-breaker.
Where to find and verify the serial number
A genuine Hublot states its identity in two places that must agree: the deeply engraved serial on the case back, and the raised serial on the warranty card. Watches made from 2020 onward add Hublot's digital e-warranty, which uses material micro-structure recognition and blockchain tracking. If the two serials differ, the engraving is shallow or smudged, or the seller can't produce the card, treat it as suspect.
The engraved case-back serial and the raised card serial must be identical. Confirm with a Hublot boutique or authorised dealer.

Scan my Hublot nowRed flags of a counterfeit Hublot
Shallow or perfectly aligned bezel screws
The clearest tell. Soft, poorly cut H-heads — or six screws all rotated to the same tidy angle — mean a fake. Genuine Hublot screws are deep, mirror-polished, and deliberately left at random orientations.
Flat, printed or wrong movement
Through the case back a Unico should show a layered, openworked skeleton with a working column wheel. A flat printed graphic, a plain quartz, or a generic automatic where an in-house caliber belongs is a counterfeit.
Wrong weight or "warm" case
Ceramic and King Gold have a specific density and cool feel; titanium is light but rigid. A watch that feels warm, hollow, or plasticky is using cheap resin or alloy, not genuine Hublot materials.
Fuzzy dial printing
Under a loupe, genuine dial text and the applied logo are crisp and even. Bleeding, thick, or misaligned printing on the dial or bezel ring is a replica giveaway.
Serial mismatch or no paperwork
A shallow, uneven, or missing case-back serial, a number that doesn't match the warranty card, or a seller who can't provide the card at all should stop the sale.
Price too good to be true
A "new" Big Bang or Big Bang Unico at a fraction of retail from an unverified marketplace seller is the classic counterfeit setup. Let the price raise your guard, then confirm with the checks above.

Frequently asked questions
How many screws are on a Hublot Big Bang bezel, and how should they look?
A Big Bang bezel is secured by six H-shaped screws. On a genuine watch each one is deeply and crisply cut into a clean, symmetrical H, machined and mirror-polished so the light reflects evenly with no burrs or tool marks. Fakes almost always give the game away here: shallow, mushy engraving, an H that is slightly off, or visible chatter around the screw heads.
Are the H-screws on a genuine Hublot all aligned the same way?
No, and this trips up a lot of people. Hublot does not rotate the six H-screws to point the same direction. On a genuine Big Bang they sit at seemingly random orientations by design, which is part of the industrial look. Ironically, some counterfeiters try to make the screws all line up neatly because they think it looks more premium, and that uniform alignment is itself a red flag.
What movement is in a Hublot Big Bang Unico?
The Big Bang Unico runs Hublot's in-house UNICO automatic flyback chronograph. The current generation is the caliber HUB1280 (Unico 2), a column-wheel chronograph with roughly a 72-hour power reserve and a skeletonised architecture, with the column wheel visible from the dial side. Genuine finishing shows real depth and openworked bridges; fakes typically hide a cheap clone or a printed dummy movement with no true skeleton work.
Do all Hublot watches have in-house movements?
No. The UNICO chronograph and several other HUB calibers are made in-house, but many time-and-date models are built on outsourced bases with Hublot finishing and modules. For example, some Classic Fusion references use HUB1110 and HUB1112 calibers derived from the Sellita SW300 (itself part of the ETA 2892 family). This is normal and not a sign of a fake, so match the movement to the specific reference rather than assuming everything is in-house.
Where is the serial number on a Hublot, and how do I verify it?
The serial number is a deeply engraved 6 to 7 digit code on the case back, usually alongside the reference number. It must exactly match the serial printed in raised characters on the warranty card. On genuine watches the engraving is sharp and you can feel it with a fingertip. Watches produced from 2020 onward also carry Hublot's e-warranty using material micro-structure recognition and blockchain tracking. Confirm the serial with an authorised dealer or Hublot directly; a mismatch between watch and card is a major warning sign.
What is Hublot's "Art of Fusion," and why does material weight matter?
The Art of Fusion is Hublot's philosophy of combining unexpected materials such as ceramic, titanium, King Gold, carbon and sapphire with natural rubber. Those materials give a genuine Hublot a specific heft and temperature feel: dense King Gold, hard scratch-resistant ceramic, or a surprisingly light but rigid titanium or sapphire case. Counterfeits use cheaper alloys and coated resin, so they often feel too light, too warm, or hollow compared with the real thing.
Which Hublot models are faked most often?
The Big Bang and Big Bang Unico are the most heavily counterfeited, followed by the Classic Fusion, Spirit of Big Bang and King Power. These carry the highest demand and the strongest visual identity, so replica makers focus on them. Whatever the model, buy from a Hublot boutique or authorised dealer, and treat a heavily discounted example from an unverified seller as suspect until every check passes.
