Short Answer
A replica Reine de Naples diamond watch is a copy of Breguet's oval ladies' timepiece, built with either a quartz or an automatic movement and a bezel set with cubic zirconia, moissanite, or lab-grown stones instead of the graded diamonds used on the original. Three things decide whether a copy looks convincing on the wrist: the case profile, the setting work around the stones, and the dial finish. None of those three depends on the price tag as much as sellers claim.
Before You Start
- A 10x jeweler's loupe for checking stone edges and prongs.
- A kitchen scale accurate to 0.1 g, since weight tells you about the case metal.
- A soft microfiber cloth and a toothbrush for inspecting and cleaning the bracelet.
- Calipers or a ruler with millimeter marks for measuring the case.
What the Original Design Does
The Reine de Naples line takes its shape from an oval pocket watch built for Caroline Murat, Queen of Naples, in the early 1800s. The modern versions keep that cambered oval case, an offset dial that sits low and to one side, a winding crown at 4 o'clock topped with a cabochon, and a bezel that carries a ring of stones. The lines are soft and asymmetric, which is exactly why cheap copies fail: an oval that is squeezed into a round-ish shape, or a bezel that flares wider at one end, reads as wrong from across a table.
Stone Type Comes First
Real versions use diamonds graded by color, clarity, cut, and carat through a recognized laboratory standard. Copies almost never do. Cubic zirconia is the cheapest option, looks glassy under a loupe, and scratches within months. Moissanite throws more rainbow fire than a diamond and often looks brighter than the rest of the watch can support. Lab-grown stones sit closest to the real look because they share the same optical properties. Ask the seller to name the stone. If the answer is vague, assume cubic zirconia.
How to Judge a Copy in Five Steps
- Lay the watch flat and trace the oval outline with your eye from the crown side, checking for symmetry between the two long curves.
- Hold the loupe over the bezel and look at the gaps between stones, since even spacing and tight prongs separate careful setting from glued-in stones.
- Weigh the watch and compare it against the stated case metal, because steel and gold-plated brass differ by tens of grams.
- Tilt the dial toward a lamp and watch how the guilloche or sunburst pattern catches light, since printed flat dials look dull and plastic.
- Rotate the crown and set the time, then feel for grit or looseness in the stem, which shows up fast on low-grade quartz builds.
Movement and Wear
Most copies run on a Swiss-pattern quartz module, which keeps time well but feels light and thin. Automatic copies cost more and add a rotor, and a decorated rotor with a branded engraving is usually the strongest visual cue on the back. Bracelet quality matters as much as the head. Look for solid end links, a clasp that snaps without rattle, and a butterfly or hidden folding clasp consistent with a ladies' dress watch. Water resistance on copies is mostly nominal, so keep the watch away from pools and showers.
Legal Reality in the United States
A watch that carries a brand name it did not earn is a counterfeit good, and trafficking in counterfeit goods is a federal offense. U.S. Customs and Border Protection seizes such shipments, and buying one online does not transfer the risk to the seller. If you want the look without the exposure, unbranded oval dress watches and gem-set fashion watches from legitimate makers give you the same silhouette with no legal problem.
