A search for "replica watch Rotonde 4004" mixes two things: a copy of a Cartier Rotonde de Cartier, and a four digit code used by sellers. The code is not part of the Cartier reference system. Cartier references for the Rotonde line use letters plus digits, such as W or CRW followed by a number. When a listing leads with "4004" and no full reference, that number is a seller tag: a batch, factory, or stock code. Ask the seller for the reference number engraved on the case back of the genuine model before you compare anything else.
Counterfeit Watch Rotonde 4004: A Comprehensive Guide
What the Rotonde line is
Rotonde de Cartier is a round case family. Case sizes in the line run from roughly 35 mm to 45 mm depending on the model. Genuine versions use in-house Cartier calibers, with chronograph, tourbillon, and simple three hand variants. Dials are usually silvered opaline, guilloche, or flinque enamel, and many models carry a blue sapphire cabochon in the crown.

What "4004" covers in listings
Factories that make copies do not publish catalogs. Codes like 4004 pass between dealers and shift meaning over time. Treat 4004 as a label for one production run, not a quality grade. Two sellers can both say "4004" and ship different watches. If a seller cannot name the movement, the case material, and the case diameter, the code tells you nothing.
Fake Watch Rotonde 4004: What the Number Means
Movement options in copies
- Quartz: thin, accurate, wrong sweep on the seconds hand.
- Asian automatic, often a 2824 or 2892 clone: correct sweep, louder rotor.
- Decorated automatic: plates and rotor engraved to look like an in-house caliber.
Ask for a movement photo and a photo of the case back. Genuine Rotonde case backs carry the reference, the serial, and the caliber number. Copies often carry a serial that repeats across units.
Price bands
Listings for Rotonde style copies run from about $60 to $500. Under $120 buys a quartz watch with a plated case. From $200 to $400 the case is usually 316L steel with a sapphire crystal. Above that, sellers claim 904L steel and cloned movements. Price does not prove quality on its own.
Checks before buying
- Measure the case. State the honest diameter in mm.
- Check the crystal. Sapphire resists a scratch from a steel pin. Mineral glass does not.
- Read the dial print under magnification. Look for bleeding edges and uneven spacing.
- Check the date window alignment against the dial and the chapter ring.
- Weigh the watch. A steel Rotonde style case at 40 mm and a leather strap lands near 75 g to 95 g.
- Look at the crown cabochon. A glued glass dot falls out. A set stone does not.
Legal note for US buyers
Trafficking in counterfeit goods is a federal offense in the United States under 18 U.S.C. 2320, and U.S. Customs and Border Protection seizes counterfeit watches in inbound mail. Buyers in the US face shipment seizure and no refund in most cases.
Short answer
Rotonde 4004 has no fixed meaning. Match the listing to a real Cartier reference, confirm the movement type and case size in writing, and treat any seller tag as marketing until the photos support it.
