A Cartier Ruban 31mm replica is a counterfeit copy of Cartier's ribbon-profile dress watch, built to a 31 mm case width. Sellers in the first copy tier describe it as their top grade: the same case silhouette, a sapphire crystal, a cabochon crown, and a quartz or automatic movement behind a closed caseback. None of it is Cartier. In the US, importing or selling it is illegal, and no replica carries Cartier's serial registration, warranty, or service support.
Cartier Ruban 31mm Replica Watch Edition Guide
What the 31 mm figure means
31 mm is the case width measured across the watch at the 3 to 9 o'clock line, with the crown excluded. Boutique catalogs, auction records, and seller pages all use that number to separate the Ruban from larger and smaller versions of the same shape. Treat any listing that never states a measured width as unverified, because "same as original" is a claim, not a dimension.
What separates first copy from cheaper tiers
- Case finishing. Better grades show a polished bezel with brushed flanks and a sharp, even break between the two surfaces.
- Dial printing. Cheap copies smear the minute track and crowd the lettering. Top tiers keep spacing consistent under magnification.
- Crown cabochon. Set stones sit flush in a metal collet. Glued ones sit proud and fall out.
- Movement. A named automatic caliber with a decorated rotor costs more than a bare quartz module, and sellers price accordingly.
- Caseback engraving. Laser etching looks flat and grey. Genuine engraving has depth and a bright cut edge.
How to inspect a listing before you consider it
Work through these checks in order. If a seller refuses any single one, stop there.

- Request a photo of the case on a caliper at the 3 to 9 o'clock line, crown excluded.
- Ask for the movement type in writing: quartz, automatic, or hand wound, plus a caliber name if one exists.
- Ask for a macro shot of the dial and check letter spacing, numeral weight, and the crispness of the minute track.
- Request a side profile photo of the crown to see whether the cabochon is set in metal or glued on.
- Ask for the caseback in raking light, then compare the serial format against photos of genuine examples.
- Confirm the return window, the payment method, and whether the seller ships from inside the US.
- Check your own exposure before paying. A US buyer who imports counterfeit goods risks seizure of the watch and loss of the money.
The US legal position
Counterfeit watches are seized at US ports of entry, and trafficking in counterfeit goods is a federal crime that carries criminal penalties. A purchase does not need to be large to be stopped. Customs can hold, seize, and destroy the shipment, and the buyer has no refund route because the transaction itself is not enforceable. Payment platforms also freeze accounts tied to counterfeit sales, which is why so many replica sellers move buyers to irreversible methods.
Cartier Ruban Replica 31mm: What to Check Before You Buy
If you want the design, not the gamble
Pre-owned genuine Cartier watches trade at a fraction of boutique pricing and come with a documented service path, so the Ruban shape is reachable without the legal risk. Cartier itself only services watches bought through its boutiques and authorized retailers, which means a seized or unsupported replica cannot be repaired by the brand at any price. Buyers who want the silhouette at a lower cost are better served by legal dress watches from established makers with 30 to 32 mm cases and clean dials.
