Short Answer

Rotonde de Cartier is a round-case line from Cartier. The code 4061 is a case reference, not a model name. Dealers put it in listings to point at a Rotonde automatic. Cartier does not publish a public table that maps 4061 to one dial color, case size, or metal, so the code alone tells you little. A fake Rotonde 4061 is a replica built to copy that reference.

Genuine Specs to Compare Against

  • Case: round and polished, in steel or gold. Most Rotonde automatic cases measure 40 mm to 42 mm across.
  • Crown: fluted, set with a blue sapphire cabochon in a polished collet.
  • Dial: Roman numerals, blued steel sword hands, guilloche or opaline finish.
  • Movement: Cartier caliber 049 on many automatic versions. It has 21 jewels, runs at 28,800 vph, and is based on the ETA 2892-A2.
  • Crystal: sapphire with an anti-reflective coating.
  • Caseback: reference number, serial number, Swiss Made, and a water resistance rating.

Where Replicas Differ

Replica batches change between sellers. Photos on a listing page may not match the shipped watch. The points below show up on most replicas of this line.

  1. Cabochon. Genuine sapphire has a deep blue tone and a smooth dome. Replica stones are glass or resin, with a flat top or a glue line at the collet.
  2. Dial print. Genuine Roman numerals have sharp edges and even stroke width. Replica print looks heavier, and the Cartier signature sits too high or too low.
  3. Hands. Genuine hands are blued steel. Replicas use painted or coated metal. At 10x magnification the coating flakes at the edges.
  4. Date window. Genuine date discs have a matte finish and a set font. Replicas show a glossy disc and off-center numerals.
  5. Caseback. Genuine engraving is cut into the metal. Replicas laser-etch, so letters look shallow and grey.
  6. Weight. A gold or steel case carries mass. Replicas with plated brass cases or thin casebacks land lighter on a scale.
  7. Movement. On models with a display back, check the rotor. Genuine caliber 049 rotors carry the Cartier name and caliber number. Replicas often use a Seagull ST2130, a Miyota 9015, or an unbranded 2824 clone.

Price Signals

Steel Rotonde automatics on the resale market list from about $4,000 to $8,000, based on year, metal, and condition. Gold versions run higher. Replica listings sit between $150 and $600. A watch sold as genuine below $3,000 with box and papers is a warning sign. Asking prices mislead. Compare completed sales.

Checks You Can Run

  1. Ask for a macro photo of the caseback with the serial readable.
  2. Ask for a movement photo with the rotor turned to show the caliber engraving.
  3. Request a timing-machine printout. Caliber 049 runs at 28,800 vph. Rate and amplitude should hold steady.
  4. Book an appointment at a Cartier boutique or an authorized service center. Staff can check the serial against Cartier records.
  5. Wind and set the watch. Genuine crown threads engage with light pressure and no grit.

Legal and Service Facts

In the United States, trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. US Customs and Border Protection seizes counterfeit watches at ports of entry. Cartier does not service replicas. Many independent watchmakers decline the work as well, because parts for replica movements do not come through normal supply channels. A replica sale carries no warranty.

Swiss Made on a dial has a legal meaning. The movement must be Swiss, and at least 60 percent of production costs must be incurred in Switzerland. A replica marked Swiss Made does not meet that standard.
