Is your Aluminium
the real deal?
The Bulgari Aluminium is a sporty, lightweight icon that combines aluminium and rubber in a design first introduced in 1998 and relaunched to great acclaim in 2020. Its accessible price point and striking Italian design have made it hugely popular — and a frequent target for counterfeiters. Here's how to authenticate yours.
How to authenticate an Aluminium
Aluminium-Rubber Construction
The genuine Aluminium features a matte aluminium case middle with a smooth rubber bezel and rubber-clad case back. The aluminium has a distinct satin-matte grain, and the rubber components integrate seamlessly with no gaps or adhesive visible. The watch weighs only 62 grams. Counterfeits often use painted steel or plastic that lacks the correct texture and weight.
BVLGARI BVLGARI Bezel Engraving
The rubber bezel features the iconic double "BVLGARI" engraving repeated around the circumference. On genuine models, the lettering is deeply and evenly embossed into the rubber with consistent depth, spacing, and font. Counterfeits show shallow, uneven engraving with inconsistent letter spacing or a font that doesn't match Bulgari's proprietary typeface.
Dial Details & Luminescence
The Aluminium dial features bold Arabic numerals (on most variants) or applied indices with bright luminous fill. The "BVLGARI" logo at 12 o'clock and "ALUMINIUM" text should be sharply printed. The date window at 3 o'clock should have a clean, beveled frame. Counterfeits show misaligned text, weak luminescence, and poorly finished date windows.
Case Back & Serial Markings
The rubber-wrapped case back on the modern automatic version features a sapphire display window showing the Caliber B77 movement. The reference number (e.g., 103382), serial number, and "SWISS MADE" are engraved around the perimeter. On genuine models, engravings are laser-precise and perfectly legible. Counterfeits have blurry or shallow markings.
Rubber Strap Integration
The rubber strap connects to the case via integrated rubber-covered lugs that form a continuous visual line. The strap has a smooth, premium feel with the Bulgari logo embossed on the deployant clasp. Counterfeits use cheap rubber that feels sticky or stiff, and show visible gaps where the strap meets the case.
Crown Design
The crown is made of aluminium with a rubber cap featuring the Bulgari logo. It should screw down smoothly for water resistance (100m on the modern version). The crown guard shoulders should be clean and symmetrical. Counterfeits have stiff or loose crowns, missing rubber caps, or poorly engraved logos.
Aluminium counterfeit warning signs
Incorrect Weight
The genuine Bulgari Aluminium weighs approximately 62 grams — noticeably lighter than a steel watch but heavier than plastic. If the watch feels too heavy (steel counterfeit) or too light (plastic), the materials are wrong.
Shiny or Polished Case Surface
Genuine Bulgari Aluminium cases have a distinctive matte, slightly grainy texture created by the sandblasted aluminium finish. If the case appears shiny, polished, or painted, it is not authentic aluminium construction.
Uneven BVLGARI Bezel Text
The double "BVLGARI" text on the rubber bezel must be evenly spaced around the full circumference with consistent depth. Any variation in letter size, spacing, or depth is a telltale sign of a counterfeit.
Cheap Rubber Feel
Bulgari uses a proprietary rubber compound for the bezel, case back, and strap that feels smooth and slightly warm to the touch. Counterfeit rubber feels sticky, plasticky, or has a chemical smell. It may also crack or discolor quickly with wear.

Frequently asked questions
What movement does the Bulgari Aluminium use?
The modern Bulgari Aluminium (relaunched in 2020) uses the Caliber B77, an automatic mechanical movement based on a reliable Swiss ebauche. It features a 42-hour power reserve and operates at 28,800 vibrations per hour. The original 1990s Aluminium collection used quartz movements, so the movement type can help date the watch. The modern automatic version is housed in a 40mm case and features a transparent case back where the movement is visible.
What is special about the Bulgari Aluminium case construction?
The Bulgari Aluminium uses a unique hybrid construction combining an aluminium case middle with a rubber bezel and rubber-wrapped case back. This gives the watch its distinctive lightweight feel (the 40mm model weighs just 62 grams) and sporty aesthetic. The aluminium has a matte, slightly grainy finish, while the rubber components are smooth and seamlessly integrated. This unusual material combination is one of the hardest aspects for counterfeiters to replicate accurately.
How much does the Bulgari Aluminium cost?
The standard Bulgari Aluminium with automatic movement (Ref. 103382) retails around $3,450, making it one of Bulgari's most accessible mechanical watches. Limited editions and special collaborations (such as the Steve Aoki or Gara Roccia editions) command premiums. The watch's accessible price point, combined with strong brand recognition, has made it popular but also an attractive target for counterfeiters producing fakes that sell for $50-200 online.
