Is your Big Bang
the real deal?
The Hublot Big Bang revolutionized luxury watchmaking with its bold "Art of Fusion" philosophy, combining exotic materials like ceramic, carbon fiber, and gold in a single timepiece. Its unmistakable porthole-shaped case and signature H-shaped bezel screws have made it one of the most recognizable watches in the world — and a prime target for counterfeiters. Here's how to tell the real thing.
How to authenticate a Big Bang
6 Visible Bezel Screws (H-Shaped)
The Big Bang's bezel is secured by six visible screws, each with a distinctive H-shaped slot that echoes Hublot's logo. On genuine models, the screws are precision-machined and sit perfectly flush with the bezel. The H slots are symmetrical with crisp, clean edges. Counterfeits often have misaligned H slots, inconsistent depths between screws, or screws that protrude slightly above the bezel surface.
Fusion Materials (Ceramic/Carbon/Gold)
Hublot's signature is combining unexpected materials. Genuine Big Bang watches use high-tech ceramic that feels cool and smooth, carbon fiber with visible layered patterns, or proprietary alloys like Magic Gold. Each material has a distinct weight, temperature feel, and finish quality. Counterfeits use painted plastic instead of ceramic, printed carbon fiber patterns, and gold-plated base metals that wear off over time.
HUB Movement Through Sapphire Back
Most Big Bang models feature a transparent sapphire case back revealing Hublot's in-house HUB caliber movement (such as the UNICO HUB1242). Look for precise finishing on bridges and rotors, proper "HUBLOT" engraving on the rotor, correct Geneva stripes or circular graining patterns, and properly beveled edges. Counterfeits use generic Asian movements that lack the refinement and distinctive layout of genuine HUB calibers.
Rubber Strap Integration
The Big Bang's natural rubber strap is a hallmark of the design. On genuine models, the strap seamlessly integrates with the case using a proprietary attachment system. The rubber should feel supple yet substantial, with a distinctive lined texture on the exterior and smooth interior. The strap should flex naturally without cracking. Counterfeits use stiff, low-quality rubber or silicone that feels plasticky, cracks at bends, and connects poorly to the case.
Chronograph Subdial Alignment
Big Bang chronograph models feature precisely positioned subdials at 3, 6, and 9 o'clock. Each subdial should be perfectly centered within its register, with hands that sit at the correct height and sweep smoothly. The subdial markings should be crisp and evenly spaced. Counterfeits frequently have off-center subdials, misaligned register rings, or hands that don't point exactly to zero when the chronograph is reset.
Crown with H Logo
The Big Bang's crown features a prominent embossed "H" logo and is protected by rubber-clad crown guards. The crown should operate smoothly with distinct positions for winding and time-setting. The H logo should be deeply and precisely engraved with clean, sharp lines. Counterfeits have shallow or blurry H engravings, crowns that feel gritty when turned, and poorly fitting crown guards that leave visible gaps.
Big Bang counterfeit warning signs
Misaligned H-Screws on Bezel
On genuine Big Bang watches, all six H-shaped bezel screws are precisely aligned and uniformly oriented. If the H slots point in random directions, vary in depth, or the screws sit unevenly within the bezel, the watch is almost certainly counterfeit.
Wrong Material Feel and Weight
Hublot uses premium materials with distinctive properties. Genuine ceramic is extremely hard and cool to the touch, carbon fiber has visible layered depth, and titanium is light yet substantial. If the "ceramic" feels warm like plastic, the carbon fiber looks flat and printed, or the watch feels too heavy or too light for its material, it is likely fake.
Cheap Movement Visible Through Case Back
Through the sapphire case back, a genuine Big Bang reveals a finely finished HUB caliber with proper decorative techniques. Counterfeit movements show unfinished surfaces, wrong bridge layouts, missing jewels, and generic rotors without the correct Hublot branding or decoration patterns.
Stiff Rubber Strap and Misaligned Subdials
The genuine Big Bang rubber strap is supple and comfortable from the first wear. If the strap feels rigid, cracks when bent, or has an unpleasant chemical smell, it is a counterfeit material. Additionally, chronograph subdials on fakes are often slightly off-center or have hands that don't reset to exact zero positions.

Frequently asked questions
What are the H-shaped screws on a Hublot Big Bang?
The H-shaped screws are one of the most iconic design elements of the Hublot Big Bang. Six visible screws are set into the bezel, each featuring a distinctive H-shaped slot rather than a standard flathead or Phillips head. On genuine Big Bang watches, these screws are precision-machined from the same material as the bezel (titanium, ceramic, gold, or carbon fiber depending on the model). The H shape should be perfectly symmetrical and uniformly deep. Counterfeit versions often have misaligned H slots, inconsistent depths, or screws that don't sit perfectly flush with the bezel surface.
What is Hublot's Art of Fusion concept?
The Art of Fusion is Hublot's founding philosophy, pioneered by Jean-Claude Biver when he relaunched the brand in 2004 with the Big Bang. It refers to the innovative combination of unusual materials in watchmaking — fusing traditional precious metals like gold with industrial materials like rubber, ceramic, carbon fiber, and titanium. For example, a Big Bang might feature a gold case with a ceramic bezel and rubber strap. This material fusion is a key authentication point because genuine Hublot watches use proprietary materials (like Magic Gold, a scratch-resistant gold-ceramic alloy) that are extremely difficult for counterfeiters to replicate.
What sizes does the Big Bang come in?
The Hublot Big Bang is available in several case sizes to suit different wrists. The standard men's size is 44mm, which is the most common and iconic dimension. There is also a 42mm version that offers a slightly more restrained presence, and a 45mm variant for those who prefer a larger watch. For smaller wrists, Hublot offers a 38mm Big Bang. The Big Bang UNICO, which houses Hublot's in-house chronograph movement, typically comes in 42mm and 44mm sizes. Each size maintains the same distinctive design DNA with the characteristic porthole-shaped case and H-screws on the bezel.
