The Breguet 7787BR is a rose-gold Classique with a 39 mm case, a moon phase, and a power reserve display. Replicas of this reference sell for US$150 to US$800. They use plated steel or brass cases, third-party automatic movements, and stamped dials. A replica is not a Breguet watch. Breguet does not service, authenticate, or repair it.

What the reference number tells you

Breguet puts the case metal into the reference code. BA is yellow gold. BB is white gold. BR is rose gold. ST is steel. PT is platinum. So 7787BR is the rose-gold version of the 7787, part of the Classique line. Breguet lists a self-winding Calibre 591 DRL inside, with a power reserve of 38 hours. The dial carries Roman numerals, a moon phase aperture, and a power reserve sector. Retail pricing sits in the five figures in USD.

How copies differ from the original

  • Case metal. Copies use brass or 316L steel with gold plating. Plating wears at the crown and lugs.
  • Movement. Most copies run a Chinese or Japanese automatic at 21,600 vph. The original runs at 28,800 vph.
  • Moon phase. On many copies a 24-hour disc drives the aperture, so the display drifts within days. Original moon phase gearing runs a 29.53-day cycle.
  • Power reserve. On low-tier copies the sector is printed and the hand does not move.
  • Dial. Guilloche on the original is engine-turned. Copies use stamped or printed patterns. The secret signature is missing or misplaced.
  • Case back. Engravings are shallow and serial numbers repeat across units.

Price bands

Entry copies run US$80 to US$200 with mineral glass and a basic automatic or quartz movement. Mid-range copies run US$200 to US$450 with sapphire crystal. The top tier runs US$450 to US$800. Plating is thicker at this level, but the base metal is still steel or brass.

Legal status in the United States

18 U.S.C. Section 2320 makes trafficking in counterfeit goods a federal crime. A first offense carries up to 10 years in prison. U.S. Customs and Border Protection seizes counterfeit shipments at ports of entry. Possession for personal use carries lower risk than sale, but a seized parcel is not returned and the money is lost. A copy has no trade-in value at an authorized dealer and no warranty from Breguet.

What to check before you buy

  • Movement calibre and beat rate. Ask for the calibre number. 28,800 vph signals a higher-grade clone.
  • Plating thickness in microns. Anything under 5 microns wears through in months.
  • Moon phase drive. Ask if the aperture runs on a 29.53-day gear or a 24-hour disc.
  • Crystal material. Sapphire resists scratches. Mineral glass does not.
  • Water resistance. Printed ratings are not pressure tested at the factory.
