Short answer
A replica Cle de Cartier in gold is a copy of the watch Cartier released in 2015. The original uses an 18k gold case and an in-house 1847 MC automatic movement. Replica versions use a plated or filled base metal case and a third-party movement. Plating depth, case weight, and movement type set the price. Most replica gold Cle de Cartier watches sell for $150 to $600. Genuine 18k gold models list above $15,000.
What the original is
Cartier named the line after the French word for key. The crown sits flush with the case and takes a key shape. Case sizes are 31 mm, 35 mm, and 40 mm. Gold options are yellow, rose, and white. The 1847 MC movement runs at 4 Hz and holds about 42 hours of reserve. Diamond-set bezels add cost.
Gold on the real watch
Cartier stamps the caseback with 750, the mark for 18k gold. That is 75 percent pure gold by weight. A 35 mm gold Cle de Cartier case and bracelet weigh over 80 grams. The metal value alone runs into the thousands of dollars at spot price.
Gold on replica versions
Replica makers use three methods. Electroplating deposits 1 to 5 microns of gold over brass or steel. Gold-filled wraps a thicker layer. "18k wrapped" is a marketing term with no standard behind it. Plating rubs off at the crown, clasp, and case edges. Wear shows in 6 to 18 months with daily use.
Movement and specs to check
Ask for the movement name before you buy. Common choices:
- Ronda or Seiko quartz. Cheapest. The seconds hand ticks once per second.
- Miyota 9015. Automatic, 28,800 vph, 42 hour reserve.
- Seiko NH35. Automatic, 21,600 vph, 41 hour reserve.
- Cloned or modified automatic with a Cartier-style rotor.
Crystal material matters. Sapphire resists scratches. Mineral glass picks up marks in months. Sapphire with anti-reflective coating on both sides adds cost and cuts glare.
Weight, size, and fit
Replica cases run lighter than solid gold. A plated brass case at 35 mm can weigh 60 grams with the bracelet. A steel case weighs more. Weight does not prove gold content. Only an assay does.
Legal and customs facts
