Short answer
A Reine de Naples replica with a mother of pearl dial and complications copies the oval case shape of the Breguet Reine de Naples line. Prices sit between about $150 and $600. The dial is often a shell composite, not nacre cut from a shell. Subdial functions vary. Small seconds and date often work. Power reserve and moon phase often do not. The movement is a stock or modified caliber from a third party factory, not a Breguet caliber.
What the original watch is
Caroline Murat, Queen of Naples, ordered a wristwatch from Abraham-Louis Breguet in 1810. Breguet delivered it in 1812. The case was oblong and sat on a wrist strap. Watch historians list it as the first wristwatch made to order.

Breguet relaunched Reine de Naples as a collection in 2002. The case is an oval, wider than it is tall. Common models measure about 36.5 mm by 28.45 mm. Smaller versions sit near 33 mm by 24.95 mm. Cases come in 18k white, rose, or yellow gold, and in steel for a few references. Bezels and lugs carry round diamonds.

Mother of pearl dials on the genuine models are cut from nacre, the inner layer of oyster or abalone shells, in slabs near 0.3 mm to 0.5 mm thick. The iridescence comes from aragonite layers in the shell. Each dial differs in pattern.

Complications in the line include small seconds, date, power reserve, moon phase, minute repeater, and tourbillon. Minute repeater references sell above $300,000. Gold models with a small seconds and a mother of pearl dial list between about $25,000 and $40,000, based on year and market. Retail numbers for every reference are not verified here.
Mother of pearl in a replica
Three materials show up on replica dials: dyed shell veneer, acetate with a pearl print, and plastic film over a metal plate. Shell veneer looks correct at arm's length. Print looks flat under a lamp, because the pattern does not shift with the angle of light. Genuine nacre shifts color as the wrist turns.
Check the dial edge under a loupe. A printed dial shows a hard line at the subdial cut. A shell dial shows layered grain at the cut edge.
Which complications work
- Small seconds: works on most replicas. It runs from the same gear train as the hour and minute hands.
- Date: works when the movement has a date mechanism. Check that the date flips between 11:50 pm and 12:10 am, not at a random hour.
- Power reserve: a printed scale with a hand that follows the winding stem, or a hand that does not move at all. Test it.
- Moon phase: often a 24 hour disc or a printed aperture. One lunar cycle takes 29.53 days. Time the disc if it matters to you.
- Minute repeater: replica versions use a lever that triggers a stamped sound plate. The strike pattern does not match hours, quarters, and minutes.
- Tourbillon: an open aperture with a balance wheel, not a rotating carriage. A real carriage turns once per minute. Watch for a full minute and count.
Checks before you buy
- Ask for the movement name and origin.
- Ask for the case metal: 316L steel, brass with plating, or gold filled. Plating of 0.5 to 3 microns wears off at the lug tips and crown.
- Weigh the watch. A gold original weighs more than a steel replica of the same size. Ask for a scale photo.
- Check crown action. It should set the hands and date without grinding.
- Read the caseback text. Replica engravings differ in font and depth from the original.
Limits
A replica is not a Breguet. It has no factory service, no warranty, and resale value near zero. Water resistance claims above 30 m on a replica do not hold. Gold plating wears at contact points within a year of daily wear. Complication parts on replica movements are the first to fail.
