Short answer
The Cartier Rotonde de Cartier Large is a 42 mm round dress watch. Genuine examples use a silvered opaline dial, Roman numerals, blued-steel sword hands, and a Cartier automatic movement. A fake copies the shape, not the case profile, dial print, or movement. Three checks catch most fakes: case thickness with a caliper, the date window, and the secret signature inside the VII numeral.
Genuine specs to use as a baseline
Steel reference W1556256 is the model most replica listings name. Cartier lists the case at 42 mm across and 9.4 mm thick. The crystal is sapphire. The crown carries a synthetic spinel cabochon. Water resistance is 30 m. The strap is alligator with a steel folding clasp. Caliber 049 runs at 28,800 vph, 21 jewels, with about 42 hours of power reserve.

Tells on a fake
- Case thickness. Fakes of this model land at 11 mm to 13 mm because of the movement inside. The genuine case measures 9.4 mm. A caliper answers the question in one measurement.
- Date window. Genuine sits at 3 o'clock with a frame and a date font that matches the dial. Fakes show a wider aperture or a date wheel that sits off center.
- Secret signature. Cartier hides part of the brand name in the stroke of the VII numeral. Fakes omit it, or print it as a smear at 10x magnification.
- Dial print. Genuine print is thin and raised. Fake print looks flat and fills in at the edges under a loupe.
- Hands. Genuine hands are blued steel with sharp bevels. Fakes are painted blue and measure thicker.
- Cabochon. Genuine is a smooth synthetic spinel dome seated flush in the crown. Fakes use glass or plastic and sit proud of the metal.
- Caseback. Check engraving depth and serial numbers. Fakes reuse the same serial across many units.
- Strap. Real alligator has visible scale pores. Most fakes use embossed cowhide.
Movement classes and price
Fakes ship with three movement types. Quartz fakes are thin but have a ticking seconds hand. Asian automatics use a Miyota 8215 or a 2824 clone. Listings that claim a Swiss ETA 2892 sit at the top of the price range. Genuine caliber 049 beats 8 times per second, so the seconds hand sweeps.
Replica listings run about $100 to $400. A $150 watch does not contain a Swiss ETA 2892. Used genuine steel examples sell in the four-figure range, and price moves with box, papers, and service records.
