1. Introduction: The Holy Grail of Dress Watches
A Tourbillon is the ultimate flex. Invented to counter gravity’s effect on accuracy, it is a mesmerizing mechanical ballet. For years, finding a high-quality JLC Master Tourbillon Replica was impossible. Most were thick, clunky, and used fake “open heart” movements that looked cheap.
APS Factory changed everything. They developed a custom movement that replicates the Calibre 978. The result is a JLC Master Tourbillon Replica that is thin, automatic, and features a genuine Flying Tourbillon cage. It is a standout piece in our curated list of High-Complication Super Clones.

Horology 101: Why is the Tourbillon So Expensive?
Most people know a Tourbillon is expensive, but few know why. Invented by Abraham-Louis Breguet in 1801, it places the escapement in a rotating cage to counteract gravity. A standard balance wheel has a few parts. A tourbillon cage has over 70 tiny parts that weigh less than a gram combined. For APS Factory to mass-produce a working tourbillon at this price point is an industrial miracle. Owning this JLC Master Tourbillon Replica is owning a piece of that engineering history.
2. The Tourbillon: Real vs. Fake
This is the most critical part of any JLC Master Tourbillon Replica. If the tourbillon looks wrong, the whole watch fails. On this APS JLC Master Tourbillon Replica, the tourbillon cage is fully functional.
What is a “Flying” Tourbillon?
- Standard Tourbillon: Has a bridge on top to hold it in place.
- Flying Tourbillon: Is supported only from the bottom. It looks like it is floating in mid-air. This is much harder to make.
- APS Execution: APS nailed it. The cage rotates once every 60 seconds. The tiny blued steel screw on the cage acts as a seconds hand. It is mesmerizing to watch. Unlike cheap fakes, this is a Real Tourbillon.
How to Spot a Fake Tourbillon
Many cheap sites sell “Tourbillon” watches that are actually just “Open Heart” movements.
- The Test: Look at the balance wheel. If it swings back and forth but the entire cage does not rotate, it is a fake. On this JLC Master Tourbillon Replica, the entire assembly spins 360 degrees every minute.
3. The Dial: “Enamel” Look
The genuine Ref. 13234E1 features a Grand Feu Enamel dial. Can a replica match that?
The Guilloché Texture
- The Pattern: The dial features a sunray pattern in the center and a complex “Guilloché” (engraved) pattern on the date ring. This level of detail is rare on a JLC Master Tourbillon Replica.
- APS Quality: While it is not real fired enamel (which costs thousands), APS uses a high-gloss lacquer with deep engraving. The light play on the blue surface is spectacular. It shifts from midnight blue to electric blue.
- The Indices: The elongated hour markers are applied perfectly, adding depth to this JLC Master Tourbillon Replica.
4. The Movement: Automatic & Thin
Most Tourbillon replicas are manual wind (you have to wind them every day). This one is Automatic.
The Calibre 978 Clone
- The Rotor: It features a large 22K gold-plated rotor. It spins smoothly to charge the watch.
- Thickness: The biggest challenge was fitting an automatic tourbillon into a thin case. APS achieved a total thickness of 11.5mm. This makes it the thinnest JLC Master Tourbillon Replica on the market. While the Gen is 11.3mm, this 0.2mm difference is imperceptible on the wrist.
- Reliability: We tested this JLC Master Tourbillon Replica on a timegrapher. It runs at a surprisingly stable +5s/day. The tourbillon mechanism is delicate but robust enough for daily wear (if treated with care).
The “Time Bomb” Myth: Is the Replica Tourbillon Reliable?
There is a myth that replica tourbillons break in a month. We tested the APS 978 clone for 6 months.
- Accuracy: It maintained +4s to +7s per day, which is comparable to a standard Seiko movement.
- Winding Efficiency: The automatic rotor winds the watch fully in about 6 hours of wear.
- Shock Sensitivity: We did not baby it, but we didn’t abuse it. It survived daily office wear perfectly. Verdict: It is robust enough for daily use, provided you don’t drop it.
Technical Deep Dive: The 21,600 vph Beat Rate
The genuine movement beats at 28,800 vph. The APS clone beats at 21,600 vph.
- Does it matter? Visually, it is hard to tell on a tourbillon because the cage is constantly moving. The slightly slower beat rate actually puts less stress on the delicate tourbillon components, potentially increasing the lifespan of the JLC Master Tourbillon Replica.
5. Maintenance Guide: Caring for a Tourbillon
Owning a tourbillon is like owning a Ferrari. It needs respect.
Rule #1: Shock Protection
- The Danger: The tourbillon cage is extremely heavy compared to a standard balance wheel, and it hangs on a single pivot (Flying).
- The Advice: Do not drop this watch. Do not play golf or tennis with it. A sudden shock can snap the pivot instantly.
Rule #2: Service Intervals
- We recommend getting the movement oiled by a professional watchsmith immediately upon receipt. Replicas often come with dry oils. A properly oiled JLC Master Tourbillon Replica can run for 5+ years.
6. On The Wrist: Pure Elegance
- Size: 40mm is the perfect dress watch size.
- Profile: Because it is thin, it slides under a dress shirt cuff effortlessly.
- The “Wow” Factor: When people see the tourbillon spinning, they assume you are wearing a house on your wrist. It is the ultimate conversation starter.
Style Guide: How to Wear It
This is a formal watch. It pairs best with:
- Navy Blue Suit: Matches the dial perfectly.
- Tuxedo: The tourbillon adds a touch of flair to black tie.
- Avoid: Do not wear this with a t-shirt and shorts. It is too dressy.
Level Up: Why You Need a Real Alligator Strap
The stock strap on the JLC Master Tourbillon Replica is “calf leather with croc print.” It’s okay, but it feels stiff.
- The Upgrade: We swapped it for a custom Navy Blue Alligator strap.
- The Result: The watch instantly felt twice as expensive. The genuine alligator scales reflect light differently than the print. The comfort level increased dramatically. If you buy this watch, budget an extra $50 for a strap—it transforms the experience.
7. Comparison: APS vs. ZF
ZF Factory also makes a JLC Tourbillon. Which is the best JLC Master Tourbillon Replica?
- ZF: Good dial, but the movement decoration is slightly rougher. The rotor noise can be loud.
- APS: Better movement finishing. The “Geneva Stripes” on the bridges are more defined. The tourbillon cage looks more refined.
- Verdict: APS is the current leader for JLC Tourbillons.

Macro Analysis: Can You Spot the Fake?
Under a 10x loupe, here are the differences between Gen ($90k) and Rep ($800):
- The Cage Finishing: The genuine tourbillon cage is hand-polished with anglage (beveling) that takes hours. The APS cage is machine-finished. It looks sharp, but lacks that “black polish” shine.
- The Screws: Genuine screws are heat-blued. APS screws are chemically blued (painted).
- The Dial Pattern: The genuine guilloché is cut by a rose engine lathe. The APS pattern is stamped. However, from 1 foot away, you absolutely cannot tell the difference.
8. Pros & Cons
The Pros
- ✅ Real Flying Tourbillon: Fully functional and mesmerizing.
- ✅ Thin Profile: 11.5mm is incredible for an auto tourbillon.
- ✅ Dial Depth: The guilloché texture is stunning.
- ✅ Automatic: No need to hand-wind daily.
The Cons
- ❌ Rotor Noise: Like many replicas, the rotor can be heard in a silent room.
- ❌ Delicate: A tourbillon is fragile. Do not drop this watch!
- ❌ Strap: The stock leather strap is stiff. Upgrade to real alligator for the full experience.
9. Final Verdict
The JLC Master Tourbillon Replica by APS Factory is a triumph. It democratizes one of the most expensive complications in watchmaking.
For less than $1,000, you get a watch that functions and looks like a six-figure timepiece. The blue dial is breathtaking, and the movement is a joy to behold.
If you want to dress to impress, this is the watch.
