Quick answer
A Cartier Rotonde small replica is a copy of the Rotonde de Cartier small model, a round watch with a 35 mm case. Replica versions sell from about $45 to $900. Three factors set the price: case size accuracy, movement type, and strap material. No replica carries a real Cartier 1847 MC caliber. Cartier does not sell that movement as a spare part.
The genuine reference
Cartier lists the Rotonde de Cartier small model at 35 mm in diameter on its product pages. Confirm the number on the live page, since Cartier retires references each year. The case comes in 316L steel or 18k pink gold. The movement is the 1847 MC, an automatic caliber with 23 jewels, 28,800 vibrations per hour (4 Hz), and about 40 hours of power reserve. The crystal is sapphire, and some references add a sapphire case back. The dial uses Roman numerals, a railway minute track, and sword-shaped hands. The crown holds a blue cabochon made of synthetic spinel or sapphire. The strap is alligator leather with a folding clasp.
Replica Cartier Rotonde Small Seconds: Real vs Fake Guide
Price tiers
- $45 to $120: quartz movement, mineral glass, plated brass or 316L steel, 34 mm to 36 mm case, PU or bonded leather strap. The seconds hand ticks once per second.
- $150 to $400: automatic movement, most often a Miyota 9015 or a Seiko NH35, 316L steel case, sapphire crystal on some units, leather strap. A 9015 beats 8 times per second; an NH35 beats 6.
- $400 to $900: decorated or clone movements, case thickness close to the original, anti-reflective coating, calf or alligator strap, engraved rotor.
Checks before you buy
- Case diameter. Ask for a caliper photo. The genuine small model is 35 mm.
- Case thickness. A thick case is the most common tell. Compare the number to Cartier's published spec.
- Movement name and beat rate. A seller who cannot name the caliber is a seller to skip.
- Crystal material. Sapphire resists scratches; mineral glass does not.
- Crown cabochon. Glass and dyed plastic show up on low tiers.
- Strap. Real alligator has a visible scale pattern and a matte finish.
Movement reality
Listings that claim a "genuine 1847 MC" are false. Common calibers inside replicas are Chinese quartz, Miyota 9015, Seiko NH35, and ETA 2824 clones with a rotor stamped to look like Cartier. Miyota and Seiko movements are reliable and serviceable. A quartz replica keeps time well but has no sweeping seconds hand. Most US watchmakers will work on a Miyota or an ETA clone. Few will touch a no-name Chinese automatic, and none will order Cartier parts for a fake.
US legal status
Counterfeit watches are illegal to import and to sell in the United States. Trafficking in counterfeit goods falls under 18 U.S.C. 2320 and carries prison terms of up to 10 years. Customs and Border Protection can seize and destroy shipments, including a single watch sent by mail. Buying for personal use does not make the item legal to import. A seized watch is not returned, and the seller rarely refunds the money.
Cartier Rotonde Small Replica: Sizes, Movements, and Checks
What a replica does not match
- Movement finishing. Cartier decorates bridges and plates; replicas print or stamp them.
- Case profile and lugs. The curve and polish differ under close inspection.
- Dial printing. Roman numeral weight and the Cartier signature vary.
- Weight. Gold models feel heavier than steel replicas that copy the look.
- Resale. A replica has no market value and no service record.
