A fake Vacheron Constantin Métiers d'Art Les Cosmos is a replica of an enamel-dial art watch. The genuine watch sells for six figures. Replicas sell for $200 to $900. The gap sits in the dial, the case metal, and the movement finish.

What the genuine watch is

Métiers d'Art is Vacheron Constantin's craft line. Dials use Grand Feu enamel, cloisonné wire, hand engraving, or guilloché. Enamel work means 20 or more kiln firings near 800 degrees Celsius. One dial can take 70 hours or more. Cases come in 18k white gold, rose gold, or platinum. Diameters run 39 mm to 41 mm. Movements carry the Hallmark of Geneva. Output per design is small. Some designs stop at 20 pieces or fewer.

What replicas copy

Replica makers copy the case shape, the crown, the lugs, the strap, and the printed layout of the dial. Photos on seller sites look close at thumbnail size. At 3x magnification the dial loses the depth of fired enamel.

Where replicas differ

  • Dial: transfer print or pad print on a metal or plastic base. No vitreous layer. No kiln.
  • Engraving: laser or die stamp. Edges look uniform. Hand engraving leaves tool marks and small depth changes.
  • Case: 316L steel with gold plating in most listings. Weight lands near 90 g. Platinum genuine pieces run past 150 g.
  • Movement: Asian automatic, often a Miyota 9015 or a decorated clone. Rotor engraving is shallow.
  • Caseback: generic text. No Geneva Seal stamp. No per-piece number that matches the case.

Numbers to check

  • Thickness: replicas run 0.5 mm to 1.5 mm thicker.
  • Lug width: 20 mm or 21 mm on genuine. Replica listings vary.
  • Crystal: sapphire on both. Replica anti-reflective coating shows a blue or purple cast.
  • Caseback screws: slotted on genuine, Phillips on many replicas.

Market notes

No replica holds value. Resale of a $500 replica lands near $200 or lower. Genuine Métiers d'Art pieces appear at auction houses and keep more of their price. Service on a genuine enamel dial is limited. Few watchmakers touch fired enamel. A cracked replica dial cannot be repaired, only replaced.

Ask the seller for a macro photo of the dial at 5x and a shot of the caseback. Ask for the movement caliber. Ask about the dial base material. Sellers who answer in detail are rare.
