The short answer
A Breguet 3358 tourbillon replica with moon phase is a hand-wound style dress watch that copies the Classique layout: compact gold-tone case, guilloché dial, exposed one-minute tourbillon near 6 o'clock, and a moon phase aperture. Expect about $180 for a decorative fake and $700 to $1,200 for a version with a working Chinese tourbillon and a moon phase that advances on a real cycle. The gap between those two ends is not the case. It is whether the cage rotates and whether the moon disc keeps time with the moon.

What the original reference does
The real Breguet 3358 family sits in the Classique line: a small gold case in the mid-30mm range, slim lugs, a hand-wound tourbillon movement, and a dial covered in engine-turned guilloché. Moon phase versions put the aperture where the dial design allows, often balanced against a power reserve or small seconds. Casebands are fluted, hands are blued steel, and the movement is visible through a sapphire back. Those are the details a replica is trying to imitate, and they are also the details that expose a cheap one.
The moon phase is where most fakes fall apart
I check the aperture before anything else. On a good replica the moon is a stamped or applied disc behind a cut window, and it moves slowly enough that you cannot see it shift. On a bad one it is printed onto a flat plate, or the disc jumps in visible steps every few hours.
- Moon disc color should be deep blue or midnight enamel with gold stars, not flat navy paint.
- The window edges should be crisp and beveled, not drilled through a sticker.
- Advance rate should be slow and even. If it clicks forward once a day, it is a calendar wheel, not a moon phase.
- Printed stars look fuzzy under a loupe. Applied ones catch light.
Tourbillon cage: working or decorative
A true one-minute tourbillon makes one full rotation per minute. Watch it for 60 seconds against a second hand. If it does not complete exactly one turn, or if it stutters, you are looking at a decorative cage over a hidden quartz or automatic movement. On better replicas you will see the balance, the escape wheel, and the cage bridge all sitting inside the rotating carriage. That level of detail is the single biggest reason to pay more.
Breguet 3358 Tourbillon Replica Watch: Best Features to Check
Dial, case, and the small stuff
Guilloché should show a turned pattern with slight depth, not a stamped texture that flattens out at the edges. Blued hands should shift color between blue and near-black as you tilt the watch. The fluted caseband should feel cut, not cast. Check the lug shape, the crown size, and the engraving on the caseback, which on cheap replicas is either shallow or misspelled.
Price tiers worth knowing
- Under $200: faux tourbillon, printed moon phase, mineral glass. Skip it.
- $300 to $600: real tourbillon movement, moon phase module, sapphire front, sapphire back on some.
- $700 and up: better finishing on the cage and bridges, accurate moon disc, correct case proportions, decent alligator-style strap.
Wear and sizing
These are small watches. Most sit between 35mm and 37mm, which wears like a vintage dress piece, not a modern sports watch. A 6.5 inch wrist handles it well. Strap width is usually 18mm or 20mm, so plan on swapping the stock strap for something softer if you wear it often. Hand-wound movements also mean you set and wind it yourself, and you should expect 40 hours or more of reserve on the better versions.
Quick checklist before you pay
- Ask for a video of the cage rotating for a full minute.
- Ask how the moon phase advances and over how many days.
- Confirm the crystal material on both sides.
- Check the return policy. Replica tourbillons can arrive with a bent cage.
- Compare the dial photo against a real 3358 listing, not against another replica.
