The short answer
If you want one replica of the Breguet Reine de Naples 8917, pick the top-tier version first. The oval case, the curved profile, and the mother-of-pearl dial are the whole point. A cheap copy gets the shape wrong, and the watch stops looking like a Reine de Naples from across the room. The best replica I would choose has a 316L steel case with rose gold plating, a curved sapphire crystal, a correct crown at 4 o'clock with a synthetic cabochon, and a dial that uses real mother-of-pearl or a convincing composite with depth. It should measure about 36.5 mm by 28.45 mm and sit near 10 mm thick.
The movement is not a 591C. No replica at this price is. What matters is a smooth automatic with a decorated rotor and a caseback that does not look like a tin can. A Miyota 9015 or a well-finished Seagull is fine. The Breguet signature on the dial should be crisp, not a blob. If the version you pick has a date, the cutout should be clean and aligned.
Why the 8917 is hard to copy
The Reine de Naples is not a round watch with a different dial. The case is an oval with a curve that wraps the wrist. The lugs are part of the case, not welded on. The dial sits under a domed sapphire. Replica makers that can do a Submariner often fail here because the case profile is visible from the side. I look at three things first: the curve of the caseback, the gap between the crystal and the bezel, and the crown. A bad replica has a flat caseback and a crown that sits too high.
Best overall: top-tier 1:1
This is the one I would buy. The case is cut from 316L steel and plated in rose gold at a thickness that does not wear through in a month. The crystal is sapphire with an anti-reflective coating. The dial has a mother-of-pearl layer with visible iridescence, not a printed scan. The hands are properly proportioned, and the crown has a cabochon that matches the case tone. The strap is alligator-grain leather with a signed buckle. Expect to pay more than the mid-tier, but less than a used gen by a wide margin. The movement is a decorated automatic, often a Miyota 9015, which is reliable and easy to service.
Option two: mid-tier
The mid-tier copy usually gets the outside dimensions right and the details wrong. The case is thicker, the crystal is mineral glass, and the dial is a flat print with a plastic sheen. The mother-of-pearl effect is a sticker. The crown is often in the right place but too large. The movement is a basic Chinese automatic with a stamped rotor. It looks acceptable in a photo and weak on the wrist. If you only wear it for a dinner, it can pass. If you care about the 8917, it will bother you.
Option three: budget
The budget version is a different watch with a Reine de Naples picture on the dial. The oval is too wide, the caseback is flat, and the lugs are wrong. The dial printing is thick. The hands are painted, not polished. The crown is a plain button. The movement is noisy. I would skip it. The money is better spent on a good strap for the top-tier version.
What to check before you buy
- Case size: about 36.5 mm by 28.45 mm. Ask for caliper photos.
- Thickness: near 10 mm. A 12 mm copy looks like a hockey puck.
- Crystal: sapphire, not mineral glass. Check for a slight dome.
- Dial: mother-of-pearl should shift color as you turn it. A flat white print is wrong.
- Crown: set at 4 o'clock with a smooth cabochon.
- Caseback: correct engravings, sapphire window, decorated rotor.
- Strap: leather with a signed buckle, not plastic.
Verdict
Pick the top-tier replica of the Breguet Reine de Naples 8917 first. The case shape and dial are the reason to own this watch. The mid-tier and budget options save money and lose the point. Buy one good copy, keep it on a decent strap, and skip the false economy of the cheap versions.
