Short answer

A fake Breguet Marine 2000 is a copy of a discontinued gold sports watch that Breguet made around the 2000 model year. Replicas of this model are scarce compared with Rolex and Patek Philippe fakes. Most examples run a Chinese automatic or a quartz movement, use gold-plated steel, and carry a printed guilloché dial instead of a cut one. Prices sit between $80 and $400. Claims of a Swiss ETA inside a Marine 2000 replica have no support.

The genuine watch

Breguet brought the Marine line to market in 1990. The 2000 generation followed with a fluted case band, straight lugs, a screw-down caseback, and a dial with hand-cut guilloché. Two references show up in auction records and dealer stock: the automatic with date, ref. 3400, and the chronograph, ref. 3460. Reference numbers vary across catalogs, so confirm the number on the caseback and the movement bridge before you trust a listing. No Marine 2000 appears in the current Breguet catalog. The model is discontinued.

Point-by-point checks

• Dial: Genuine guilloché is cut into metal with a rose engine. Fakes print the pattern or stamp it shallow, so the lines look flat under a loupe.
• Hands: Breguet hands are blued steel with a hollow eccentric tip. Fakes use painted or plated hands, and the tip shape is wrong.
• Case band: Genuine fluting is machined, then finished by hand, with crisp edges and even spacing. Fakes show soft edges and uneven gaps.
• Numbers: Genuine watches carry a matching serial on the caseback and the movement. Fakes repeat one number across a batch.
• Movement: Replicas use a DG2813-class automatic or a quartz module. Bridges are gold-plated with no perlage and no anglage.
• Metal and weight: Many fakes are plated steel sold as solid gold. A scale reading and a magnet test give more information than photos.
• Date window: Check the aperture position and the font. Both sit off on most copies.

Price bands

Quartz copies sell for $80 to $150. Automatic copies sell for $150 to $400. Anything above $400 tends to be advertised as a Swiss-movement replica. For this model, that claim does not hold up, because no factory produced a high-grade Marine 2000 case set.

What this guide cannot confirm

Photos do not verify a movement, a metal composition, or a serial. A watchmaker with a caseback tool and a timing machine settles those questions in minutes. Treat any listing that blocks an inside view as unverified.
