Quick answer

The Breguet Reine de Naples is an oval watch. Breguet launched the modern collection in 2002. The shape traces to a watch Abraham-Louis Breguet delivered in 1812 to Caroline Murat, Queen of Naples. Tourbillon references sit at the top of that collection. Fakes run from about $150 to $1,200. Most fakes under $400 do not contain a tourbillon. They contain an open aperture and a balance wheel that does not orbit.

What the original is

Caroline Murat ordered the watch in 1810. Breguet delivered it in 1812. The piece had an oblong case, a silver dial, and a strap worn on the wrist. Breguet and the major auction houses call it the first wristwatch. The modern Reine de Naples reuses the oval case and the off-center dial layout.

Case sizes run small. The 8908 measures about 36.5 mm by 28.5 mm. The case is longer than it is wide and it curves at the lugs. Breguet fits in-house movements with hand finishing, engraved bridges, and silicon escapement parts on current references. Diamond references use cut stones set in gold. The stones go on the bezel, the dial flange, or both.

What fake versions copy

Fakes copy four things: the oval case, the dial, the stone bezel, and the caseback engraving. Most do not copy the movement.

  • Case: plated brass or 316L steel with gold plating. Weight is lower than solid gold. Plating wears through at the lugs inside a year of daily wear.
  • Stones: cubic zirconia or moissanite. A thermal tester separates them from diamond in seconds.
  • Glass: mineral crystal on most fakes under $300. It scratches. The original uses sapphire.
  • Dial: printed pattern instead of hand-turned guilloche. Under 10x magnification the lines are flat and the spacing drifts.

Real tourbillon vs fake tourbillon

A tourbillon puts the balance wheel and the escapement inside a cage. The cage turns 360 degrees once per minute. That rotation averages out rate errors caused by gravity.

You can test one. Time a full turn of the cage against a stopwatch. It should take 60 seconds.

Chinese tourbillon movements from Seagull and Hangzhou exist and the cage does rotate. Replicas built on those movements cost more, often $500 and up. Fakes below that price use one of three tricks:

  1. An open-heart window at 6 o'clock showing a balance wheel that oscillates but never orbits.
  2. A disc driven by the seconds train. No balance and no escapement sit inside it.
  3. A fixed bridge cut to look like a cage. It does not move at all.

Price bands

  • $120 to $250: quartz or low-grade automatic, CZ stones, mineral glass, no tourbillon.
  • $250 to $450: automatic movement, better case finish, CZ or moissanite stones.
  • $500 to $1,200: Chinese tourbillon movement, sapphire glass, gold plating. Some sellers claim solid gold at the top of this range. Verify that with a jeweler.

Checks before you buy

  1. Ask for a macro photo of the caseback. Breguet engraves reference numbers. Laser printing looks dotted under magnification.
  2. Ask for a 60-second video of the tourbillon cage, uncut.
  3. Ask for the case metal and a gram weight.
  4. Ask for photos of the clasp, the crown, and the strap stitching.

Limits

Factory names stay private. Sellers use code letters. No public list maps a code to a workshop. Nothing here verifies a specific seller or a specific listing. A fake carries no Breguet warranty and no Breguet service. Resale value is close to zero.
