The Breguet Reine de Naples 8918 is an oval dress watch with a grand feu enamel dial, a diamond-set bezel, and a briolette-cut diamond set into the crown at 4 o'clock. The shape is so recognizable that copies are everywhere, from cheap quartz ovals that share only the silhouette to automatic fakes that survive a casual glance. The straight answer: no single photo confirms a real 8918. You confirm it by checking four things in order. The case dimensions, the enamel dial, the crown stone, and the movement behind the sapphire back.
Before You Start
- A 10x jeweler's loupe
- Digital calipers that read to 0.01 mm
- The full reference number from the seller, in writing
- Daylight plus a small LED light
- A phone with macro mode for close photos
Step-by-Step Checks
- Get the complete reference number. An 8918 is never sold as "8918" alone. The letters that follow identify the case metal, for example 8918BB for white gold and 8918BR for rose gold. Ask for a photo of the engraving on the caseback, not the text of the listing.
- Measure the case with calipers. The genuine oval case is roughly 36.5 mm by 28.45 mm and about 10 mm thick. Copies tend to run 1 to 2 mm off in one direction, which changes the whole proportion of the dial.
- Locate the crown and inspect its stone. The crown sits at 4 o'clock and is tipped with a briolette diamond of about a quarter carat, drilled and fully faceted. Fakes use a foil-backed paste stone, a flat-bottomed cubic zirconia, or a glued bead. Under the loupe the difference is immediate.
- Study the dial surface. Grand feu enamel is powdered glass fired onto a metal base. Under a loupe it reads as a deep, glassy, slightly irregular surface with soft reflections. Fake dials are lacquer, resin, or printed film: flat, plastic-looking, and often showing a faint dot pattern from inkjet printing.
- Read the printing. The Breguet signature and the numerals have sharp, clean edges with even stroke weight. Counterfeit printing looks heavier, slightly fuzzy, or raised above the surface.
- Check the hands. Breguet hands are blued steel with hollowed eccentric tips. Fakes are usually painted or black chrome, with blunt tips and the wrong length relative to the chapter ring.
- Examine the bezel setting. Genuine stones are grain set with tiny gold beads, evenly spaced, with no gaps and no adhesive. Copies use fewer and larger stones, irregular spacing, and visible glue at the edges.
- Turn the watch over. Caliber 591C is an automatic movement with roughly 38 hours of reserve. Look for Geneva stripes on the rotor, blued screws, polished bevels, and the Breguet name engraved into the metal. Fakes show a plain rotor, printed markings, and a plastic movement ring.
- Match the serial number to the paperwork. The number engraved on the caseback must match the warranty card and the certificate. If the seller cannot show both, stop.
- Get an expert opinion. A watchmaker or a Breguet boutique can pull service records for the serial. On a watch at this price level, a paid inspection is cheap insurance.
Where Most Fakes Fail
Nearly every counterfeit gets the outside close enough to fool a phone camera. The failures cluster in three places: the enamel, which never has the depth of fired glass; the setting, where spacing and bead work are sloppy; and the movement, which is a generic automatic with no decoration. Case thickness is the fourth giveaway, because the copy houses a thicker movement in a case that should be slim.

Legal Note
Importing or selling a counterfeit watch is illegal in the United States and in most of the European Union. A watch offered far below the secondary market price for an 8918, with vague paperwork and no service history, is a counterfeit regardless of how good the photos look.
