Short answer
A Breguet 3358 replica does not run a Breguet movement. Most copies use a Chinese tourbillon caliber or, in cheaper builds, an open aperture that hides a plain balance wheel. The visible gaps sit in case thickness, tourbillon cage finish, dial engraving, and case metal. Two replicas from different factories can differ more from each other than either differs from the photos in a listing. Measure the watch, do not read the listing.

The genuine reference
Breguet filed the tourbillon patent in 1801. Reference 3358 belongs to the Classique line: a round case in yellow gold or white gold, tourbillon at 6 o'clock under a sapphire bridge, fluted caseband, hand-wound movement. Case diameter sits near 35 mm to 36 mm. Breguet does not publish full measurements for this reference today, so confirm diameter, thickness, and caliber number against an auction catalog before you compare. Exact thickness and caliber number are not confirmed in this guide.

Tourbillon carriage
On the genuine watch the cage turns one time per minute. The carriage screws are polished, the bevels are drawn out by hand, and the balance sits inside the rotating cage. Replica tourbillons from Seagull and Hangzhou also turn near one minute per rotation, but the cage arms are thicker, the screws are unpolished, and the balance staff often sits off center. A fake tourbillon shows a static aperture with a balance wheel that does not rotate as a cage. Watch the opening for 60 seconds and count.

Case and dial
Genuine cases are 18k gold. Replicas use gold plating over steel, PVD, or a thin gold wrap. A solid gold case is heavier than a plated steel case of the same size, so a scale and a caliper settle the question in one minute. Breguet cuts even grooves into the fluted caseband; copies show shallow or uneven cuts near the lugs.

Genuine dials carry hand-turned guilloche. Replica dials are stamped, and the pattern loses depth under a loupe. Breguet used a secret signature on some dials starting in 1795; replicas either omit it or print it too dark. Blued steel hands on the genuine watch show heat color; many replicas paint the hands blue.
Inspection checklist
- Measure case diameter and thickness with a caliper.
- Watch the tourbillon cage for 60 seconds.
- Weigh the watch head on a kitchen scale.
- Photograph the caseback engraving and serial format.
- Ask for a photo of the movement and the caliber stamp.
- Compare dial print against a reference photo of the genuine dial.
Price bands
Replica tourbillons sell for about $400 to $900. Plated automatic copies with a fake aperture sell under $150. An 18k gold Breguet tourbillon of this period sells in the tens of thousands of dollars at auction. Check recent sale results for current figures.
What is not known
Production years for the 3358 and its caliber number are not confirmed here. Breguet archive pages for discontinued references are thin. Treat any listing that quotes a caliber number as unverified until a catalog or the brand confirms it.
