Short answer: a watch sold as a "1:1 fake Cartier Baignoire 2717" is a counterfeit, and there is no authorized version of that product to compare it with. The number 2717 is a Cartier case reference stamped inside genuine Baignoire watches from one production period, and counterfeiters reuse it on generic cases to borrow that credibility. If your goal is to avoid a bad purchase, the question worth answering is how to confirm that a Baignoire in front of you is genuine.
What the 2717 reference actually is
Cartier marks its watches with a case reference and a serial number, usually inside the caseback and repeated on the accompanying paperwork. A reference such as 2717 identifies a case and movement configuration from a specific era of Baignoire production. It is not a model name, and it is not a quality grade. A stamp reading 2717 tells you only that someone put those four digits on the metal. On counterfeit watches the engraving is often shallow, uneven, or cut with a laser rather than struck with a die, and the surrounding text and hallmarks do not line up with the geometry of the case.
Red flags on a supposed Baignoire 2717
- Caseback engraving that looks printed or lasered rather than struck, with soft edges and inconsistent depth.
- Lettering that departs from Cartier's house fonts, most often on the oval case where counterfeit profiles run slightly too wide or too flat.
- A cabochon that is glass or colored resin rather than a smooth synthetic sapphire set into the crown.
- Hands that are painted rather than blued steel, or that show tool marks near the pivot.
- A movement visible through the back that is a generic automatic with no Cartier finishing or numbering.
- Box, papers, and serial numbers that do not match each other or the case.
- A price far below the range that genuine examples in comparable condition trade for.
Authenticated pre-owned versus a counterfeit
Buying an authenticated pre-owned Baignoire
- Pros: it holds value, Cartier and independent watchmakers will service it, it can be insured, and it is legal to own and resell.
- Cons: the entry price is higher, availability for one specific reference is limited, and condition varies from piece to piece.
Buying a 1:1 replica
- Pros: the purchase price is lower.
- Cons: importing or selling counterfeit trademarked goods is illegal in the United States, the brand will not service the watch, there is no resale channel, and the shipment can be seized in transit.
How to verify a Baignoire before you pay
- Ask the seller for the case reference and serial number, then have an independent watchmaker open the case and compare the movement and caseback stamps.
- Request the original invoice or a Cartier service record, and call Cartier with the serial number to ask what its records show.
- Compare the case profile, lugs, crown, and dial printing against photographs of known genuine examples of the same reference.
- Weigh the watch and measure the case. Counterfeits usually miss on dimensions and mass.
- Pay in a way that allows a dispute, and use an escrow or authentication service when the seller will not meet in person.
Bottom line
A fake Cartier Baignoire 2717 is not a shortcut to a Baignoire. The reference number is one small piece of a larger authentication puzzle, and the counterfeits that carry it tend to fail on case geometry, engraving, movement, and paperwork. If you want the look of the Baignoire at a lower entry point, an authenticated pre-owned example or a serviceable vintage piece from a reputable dealer is the route that keeps your money recoverable and the watch wearable.
