Replica movement options

Most replica 1538420 watches use a modified ETA 7750 or a Chinese clone of the 7750. Some high-end replicas use a custom clone of the calibre 759. The clone movement has a 40-hour power reserve. The genuine movement has a 65-hour reserve. The clone movement has a noisy rotor. The date change on replicas can be slow. The moonphase on replicas is a 24-hour disc, not a true 29.5-day cycle.

Visual differences

  • Subdial spacing: replicas place subdials too far apart or too close.
  • Moonphase disc: replicas show a sun and moon that rotate once per day.
  • Case finishing: replicas have softer edges on lugs and bezel.
  • Dial printing: replica text is thicker or thinner than genuine.
  • Hands: replica hands are too short or have wrong shape.

Price ranges

Low-end replicas cost $100 to $300. These use a 21-jewel movement and mineral glass. Mid-tier replicas cost $300 to $500. These use a 7750 clone and sapphire glass. High-end replicas cost $500 to $800. These use a custom clone movement and better finishing. No replica matches the genuine watch in movement finish or accuracy.

Legal status

Counterfeit watches are illegal to sell or import in the United States. U.S. Customs and Border Protection seizes counterfeit goods. The penalty for trafficking counterfeit goods can be up to 10 years in prison and a $2 million fine for a first offense. Buying a replica for personal use is not a federal crime in most cases, but the item can be seized.

Identification tips

  1. Check the subdial spacing. Genuine subdials sit at 3 and 9 o'clock with correct spacing.
  2. Check the moonphase. Genuine moonphase advances once per day. Replica moonphase advances once per day but shows a 24-hour cycle.
  3. Check the caseback. Genuine caseback has a sapphire crystal and a correct reference number.
  4. Check the movement. Genuine calibre 759 has a gold rotor and Côtes de Genève finish.
  5. Check the price. A genuine 1538420 sells for $12,000 to $15,000 on the secondary market.
