Short answer
3820BR is a Breguet reference number. It is the rose gold version of the Breguet Type XX Transatlantique chronograph. A search for "fake type xx 3820br" points to replica watches built to look like that model. No replica uses the Breguet movement. US law treats such watches as counterfeit goods.
What the number 3820BR means
Breguet numbers its references and adds a two-letter material code. BR is rose gold. ST is steel. BA is yellow gold. BB is white gold. PT is platinum. The Type XX Transatlantique 3820 entered the Breguet catalog in the mid-1990s and left it in the 2000s. Breguet sells later Type XX models today, not the 3820.
The Type XX name comes from a French military aviation specification from the 1950s. Breguet built chronographs for the French air force under that spec. The Transatlantique is the civilian re-edition.
Genuine 3820BR spec points
- Case: 39 mm, rose gold, sapphire crystal
- Movement: Breguet cal. 582, self-winding flyback chronograph with date
- Dial: engine-turned pattern with Breguet hands and numerals
- Water resistance: 100 m on the original spec sheet
- Caseback: engraved reference, serial number, and material code
What replica 3820BR watches use
Replica cases are steel with gold plating. Plating thickness varies by price. Movements fall into three groups: quartz, hand-wound Seagull ST19 chronographs, and automatic chronograph movements with a decorative rotor. None is a Breguet 582. None has the Breguet flyback mechanism.
Weight is a rough test. Solid rose gold is dense. Plated steel of the same size is lighter. Makers do not publish case weights, so exact figures vary by unit.
Checks on a replica 3820BR
- Crystal material. Mineral glass scratches. Sapphire does not.
- Dial pattern. Real engine-turning shows cut lines. Replicas print the pattern.
- Logo and signature. Replica printing shows thick strokes and soft edges.
- Subdial spacing and date window position against photos of a genuine dial.
- Chronograph pushers. Test start, stop, reset, and flyback.
- Caseback engraving depth and serial format.
- Lume on hands and markers, if present.
Prices
Replica Breguet Type XX listings run from about $120 for quartz to $400 and up for automatic versions. Replica prices do not track gold prices because the cases are not gold. Genuine 3820BR examples sell on the secondary market for several thousand dollars and more, based on condition and papers. Ask a dealer for current figures.
Legal position in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. § 2320. US Customs and Border Protection can seize shipments. A watch that carries a Breguet trademark but was not made by Breguet is a counterfeit, whatever the seller calls it. Terms like "first copy", "1:1", and "mirror quality" are marketing labels, not legal categories.
