The fake Cartier Ruban 34mm is a counterfeit version of Cartier's 34 mm Ruban, a women's watch whose case and lugs are shaped as one continuous ribbon. Copies of this model are far less common than Tank, Santos or Ballon Bleu copies, because the ribbon profile is expensive to reproduce. The fakes that do circulate split into two groups: quartz pieces that read correctly from a few feet away, and automatic copies that get the bracelet right but miss the case curve. Neither is a Cartier product. In the United States, importing or selling one is illegal.
Prerequisites
- 10x jeweler's loupe
- Digital calipers that read to 0.01 mm
- Bright, diffused light and a clean cloth
- A reference photo of a genuine Ruban 34 mm
- Awareness that buying, importing or reselling a counterfeit watch violates US law
What the genuine Ruban 34 mm looks like
Cartier builds the Ruban around a case that bends like folded ribbon, so the lugs and the case body form one unbroken arc with no visible seam. The dial is clean, with Roman numerals or a plain variant, and the crown carries a blue spinel cabochon. The 34 mm width is measured across the case at its widest point, excluding the crown. Casebacks are engraved, not printed, and the bracelet flows into the case line instead of sitting on top of it.
How to inspect a suspected counterfeit Ruban 34 mm
- Measure the case across its widest point with calipers and confirm it reads 34.0 mm; copies often land at 33 mm or 35 mm.
- Run a fingertip along the joint between the case and each lug and feel for a step, ridge or gap.
- Examine the crown cabochon under the loupe; genuine stones show depth and a polished dome, while fakes show bubbles, a flat top, or dye that pools at the edge.
- Study the dial signature at 10x and compare stroke weight and letter spacing against your reference photo.
- Angle the caseback under light and check whether the engraving has crisp cut edges or a shallow raised look from a stamped or laser etched copy.
- Inspect the bracelet links and clasp for stamped hallmarks, screw heads with clean slots, and even polishing.
- Ask the owner for service papers or a movement photo; a quartz movement or a battery hatch under the caseback ends the question at once.
- Compare the watch weight against the published weight for the same case metal; copies feel light for their size.
Price tells
A genuine Ruban 34 mm sits in the four and five figure range depending on metal and condition. Listings that price it at a small fraction of that figure, or that ship from a wholesale replica seller, are counterfeit by definition. A discount alone never proves a watch is fake, but a steep discount on a current Cartier model with no service history is a strong signal.
US legal reality
US Customs and Border Protection treats counterfeit watches as prohibited merchandise and can seize shipments at the border. Selling a counterfeit Ruban as a Cartier watch is trademark counterfeiting and can carry civil damages and criminal penalties. If you already own a copy, do not resell it as genuine. A jeweler or a Cartier boutique can document what you have, and disclosure protects you from a fraud claim later.
