What is a fake Clé de Cartier automatic?
A fake Clé de Cartier automatic is a replica of the cushion-case Cartier dress watch introduced in 2015, fitted with a copied automatic movement instead of the in-house 1847 MC caliber. The genuine watch runs a 23-jewel Swiss automatic with a 42-hour power reserve, while replicas usually carry a decorated Seagull ST2130, a Miyota 9015, or a cloned ETA 2892. The differences show up in the key-shaped crown, the caseback engraving, and the finish on the dial and hands, not in the name printed on the dial.
What gives a fake Clé de Cartier away?
- Crown. The genuine crown is shaped like the head of an old-fashioned key, with a sapphire or spinel cabochon set into the flat face. Replicas often mold the crown too wide, sit the stone too high, or glue a plastic cabochon in place.
- Case proportions. Genuine Clé de Cartier cases measure 31mm, 35mm, and 40mm across. Copies often run slightly wider and feel light in the hand because the steel walls are thinner.
- Dial and hands. The real dial uses a silvered opaline or sunray finish with printed Roman numerals and blued steel sword hands. Copies show thicker printing, painted blue instead of heated blue, and numerals that crowd the date aperture.
- Caseback. Genuine engraving is deep and crisp, with the reference number, serial, and Swiss Made aligned along the edge. Replica engraving looks shallow or laser-etched, and the serial font shifts between batches.
- Movement finish. On display-back models, the 1847 MC shows Geneva stripes, blued screws, and a signed rotor. Copies show coarse perlage and a rotor that spins with an audible rattle.
What movement does a replica Clé de Cartier automatic use?
Most replicas run one of three movements: the Seagull ST2130, a Chinese take on the ETA 2824, the Miyota 9015, or a cloned ETA 2892 in the pricier builds. All three keep time well enough for daily wear, and none match the finishing or the 42-hour reserve of the 1847 MC. The Miyota 9015 beats at 28,800 vibrations per hour, the same rate as the genuine caliber, so a beat-rate check alone will not separate them.
Which Clé de Cartier models get copied most?
Replica makers focus on the steel automatic references, since those sell in the highest volume and the case finishing is easiest to fake. Two-tone and gold-plated versions appear next to them on the same storefronts. Solid 18k rose or yellow gold pieces are rarely matched, because plating wears through at the crown and lugs within months of daily wear.
What should you check before buying a replica Clé?
- Ask for macro photos of the crown and caseback, not studio renders.
- Request a movement photo or a short clip with the rotor turning.
- Compare the stated weight against the seller's spec sheet, since thin cases come in noticeably light.
- Confirm the water resistance claim. Most replicas are splash resistant at best, and the crown gasket is the weak point.
- Check the strap or bracelet font on the clasp, where cheap engraving shows first.
Frequently asked questions
Is the Clé de Cartier automatic a real Cartier model?
Yes. Cartier launched the Clé de Cartier in 2015 and fitted the automatic versions with the 1847 MC, an in-house Swiss caliber built for volume production.
How much does a fake Clé de Cartier automatic cost?
Replica prices run from about $150 for basic builds to $600 for high-end copies with cloned movements. Genuine steel automatics retail far above that, and pre-owned examples trade below original retail.
Will a jeweler notice a replica Clé de Cartier?
A trained watchmaker will, usually within seconds. The crown shape, the engraving depth on the caseback, and the rotor finish carry details that copies do not reproduce.
