Brand profile: Blancpain
Blancpain is a Swiss luxury watch manufacturer in the upper price segment (8,000–500,000+ EUR), known for the Fifty Fathoms dive watches and classic complications. Primary counterfeiting targets are the Fifty Fathoms, Villeret, and Léman models. The brand is counterfeited less frequently than Rolex/Omega, but Super Clones of the Fifty Fathoms have increased significantly in recent years.
- Movement finish: Originals use manufacture movements (Cal. 1150, 1315, 1335, 6654) with specific Côtes de Genève, blued screws, and a gold rotor with Blancpain engraving. Fakes typically use ETA/Miyota with printed decorations and poor finish quality.
- Lume: Blancpain uses a special LumiNova in warm beige/cream tones on vintage-inspired models. Fakes often have lume that is too white, too greenish, or unevenly applied with unclean edges.
- Date disc: The original has a specific typeface with a characteristic '4' and '9', perfectly centered in the window with anti-reflective coating on both sides. Fakes often show missing AR coating, the wrong typeface, or alignment errors.
- Crown details: Original crowns feature a finely engraved 'JB' logo (Jehan-Jacques Blancpain) with precise lines and specific knurling. Fake crowns show blurred engravings, incorrect proportions, or overly smooth surfaces.
Serial number format: From the 2000s onward, Blancpain uses a format of 4 digits, hyphen, 4 digits (e.g. 0856-1234). Serial numbers are engraved both on the case (between the lugs at 6 o'clock) and on the movement. Newer models (from ~2010) may feature longer alphanumeric serial numbers. The engraving is precise with uniform depth and sharp edges — never etched or laser-engraved with discoloration. Fakes often show engravings that are too shallow or use the wrong typeface.
