1. Introduction: Testing the “Impossible” Clean Factory Rolex Daytona Le Mans
In 2023, Rolex shocked the watch world with the release of the Le Mans Daytona to celebrate the 100th anniversary of the legendary endurance race. This special white gold model (Reference 126529LN) featured a brand-new movement and a vintage-inspired dial. For replica manufacturers, this presented a massive challenge. They couldn’t simply reuse the old 4130 movement found in standard Daytonas. They had to engineer a completely new 4132 clone movement to handle the unique 24-hour counter. Most industry experts said, “This cannot be replicated quickly.”
However, Clean Factory proved them wrong. They released the definitive Clean Factory Rolex Daytona Le Mans replica with a modified gear train that mimics the 24-hour function perfectly. But does it actually work reliably in daily use? Is the open caseback finishing up to par? I wore this Clean Factory Rolex Daytona Le Mans for a full week to find out if it lives up to the hype.

2. The Movement Revolution: The 4132 Clone
This is the most critical part of this review. Unlike standard Rolex models, the movement in the Clean Factory Rolex Daytona Le Mans is visible through a sapphire exhibition caseback, so it must be visually perfect.
The 24-Hour Miracle
The most significant feature of the Clean Factory Rolex Daytona Le Mans is the functional 24-hour counter at the 9 o’clock position.
- The Test: I ran the chronograph function for a full 24-hour cycle to verify its mechanical accuracy.
- The Result: The sub-dial hand moved exactly one full rotation in 24 hours. It works perfectly. This is not a cosmetic hand glued in place; it is geared correctly into the movement architecture.
- Engineering: Clean Factory achieved this by modifying the gear ratios of the trusted Dandong 4130 base. This requires precise calculation and custom parts, which explains why the Clean Factory Rolex Daytona Le Mans commands a premium price compared to standard Panda models.
Winding & Setting Experience
- Winding Feel: The crown has a distinct, mechanical resistance when winding. It feels tighter than a standard VS 3235 but very precise. You can feel the mainspring tension building up inside the Clean Factory Rolex Daytona Le Mans.
- Chronograph Feel: The start/stop pusher requires a firm press (approx. 1.5kg of force). The click is loud and satisfying, typical of a column-wheel chronograph found in high-end Rolex 126529LN replicas. The reset is instant and snaps back to zero without any “bounce.”
Visual Finishing
Through the open caseback, the movement is a feast for the eyes.
- Decoration: The bridges feature “Côtes de Genève” (Geneva Waves) that are deep and reflective.
- Engraving: The text “ROLEX 4132” is engraved in gold, not printed. It looks sharp under a loupe.
- The Rotor: The skeletonized 18k gold-plated rotor spins smoothly on ball bearings. While it is slightly noisier than a genuine sleeve bearing rotor, it is acceptable for a replica of this caliber.
3. The Dial: A Tribute to Paul Newman
The dial of the Clean Factory Rolex Daytona Le Mans is a love letter to vintage collectors. It brings back the “Exotic Dial” vibe of the 1960s Ref. 6239/6241, famously known as the “Paul Newman” dial.
The “Square” Markers
Look closely at the three white sub-dials on the Clean Factory Rolex Daytona Le Mans.
- Design: Instead of the simple lines found on standard modern Daytonas, the markers have small “square” tips (lollipops). This is the signature of the Paul Newman style.
- Clean’s Execution: The printing is incredibly sharp. The squares are distinct and crisp, not muddy or bleeding. The white color is a specific Warm White (slightly creamy), matching the vintage aesthetic of the genuine Clean Factory Rolex Daytona Le Mans perfectly. It avoids the “cold blue-white” look often found on cheaper replicas.
Sunburst Black
The main dial features a deep black sunburst finish.
- Lighting: Under direct sunlight, the radial brushing catches the light, creating a charcoal grey reflection. Indoors, it looks ink black. This dynamic range is a hallmark of high-end Rolex 126529LN replicas.
- Sub-dial Rings: The white rings are slightly recessed, giving the dial depth and a 3D effect.
Lume & Indices
The applied white gold indices are thinner and sharper than the previous 116500LN. They are filled with Chromalight (Blue), which contrasts beautifully with the warm white sub-dials. The application is flat and even, with no overflow on this Clean Factory Rolex Daytona Le Mans.
4. The Bezel: The “Red 100” Ceramic
The bezel is the second most important visual feature of the Clean Factory Rolex Daytona Le Mans. It is unique to this specific anniversary model.
(The Red “100”
To honor the 100th anniversary of the race, the number “100” on the tachymeter scale is colored in bright red ceramic.
- The Technology: Clean didn’t just paint it red. They used a Red Ceramic Glaze process on the Clean Factory Rolex Daytona Le Mans. The red material is filled into the engraved number and baked at high temperatures.
- The Result: The red color is vibrant, not dark or dull. It pops against the black ceramic background and is resistant to fading, ensuring your Clean Factory Rolex Daytona Le Mans looks pristine for years.
Platinum PVD
The rest of the numbers are coated with Clean’s signature Platinum PVD. They shine with a dusty silver brilliance that mimics genuine platinum dust. This ensures the numbers won’t fade or turn grey over time, a common issue with lower-tier Rolex 126529LN replicas.
The Steel Ring
Like all new 1265xx Daytonas, the ceramic insert sits inside a polished steel ring. Clean Factory has mastered the fitment here—there is zero gap between the ceramic and the metal ring. The transition is seamless to the touch on this Clean Factory Rolex Daytona Le Mans.
5. Case & Material: The White Gold Question
The genuine 126529LN is made of solid 18k White Gold. The Clean Factory Rolex Daytona Le Mans is made of 904L Stainless Steel. Does it matter?
Color Tone
- Genuine: White gold has a slightly warmer, “grey-yellow” undertone compared to steel.
- Replica: 904L steel is brighter and whiter.
- Verdict: In isolation, no one can tell. Side by side with a genuine white gold watch, the steel looks a bit “colder.” However, Clean Factory’s polishing is so good that it mimics the high-gloss luster of gold very well on the Clean Factory Rolex Daytona Le Mans.
Hallmarks
Because the genuine is gold, it has hallmarks (stamps) on the back of the lugs.
- Clean’s Detail: Clean Factory has engraved these hallmarks (750, Scales, St. Bernard Dog head) deep into the steel lugs using CNC technology. They are sharp and visible under a loupe, adding a layer of authenticity to this Rolex 126529LN replica.
6. The Weight Issue: Steel vs. Gold
- Genuine: ~160 grams (Heavy).
- Clean Factory: ~140 grams (Steel weight).
- Analysis: The 20g difference is noticeable if you hold them in both hands. But on the wrist, 140g is substantial enough to feel premium. Currently, there is no “Tungsten” version of the Le Mans that matches Clean’s quality, so the Clean Factory Rolex Daytona Le Mans is the best option despite the weight difference.
7. Comparison: Clean Factory vs. QF Factory
QF Factory (Quartz Factory) also released a Le Mans version with a Tungsten (Weighted) case. Which is better?
| Feature | Clean Factory | QF Factory |
|---|---|---|
| Movement | Dandong 4132 (Real 24h) | Shanghai 4130 (Fake 24h) |
| Weight | ~140g | ~160g (Tungsten) |
| Dial Color | Warm White (Correct) | Bright White (Wrong) |
| Bezel Red | Deep Ceramic Glaze | Painted Red |
| Price | Higher | Lower |
Verdict:
- Buy Clean if you want the Real Function (4132 clone movement) and Better Dial. The dial accuracy is more important visually than weight.
- Buy QF if you only care about the Weight and don’t mind the wrong movement function.

8. Who Should NOT Buy This Watch? (Honest Advice)
This watch is amazing, but it is not for everyone.
- Avoid if: You are rough on watches. The complex 24-hour chronograph gearing is more delicate than a standard 4130. Dropping it could misalign the gears of the Clean Factory Rolex Daytona Le Mans.
- Avoid if: You expect it to pass a microscope test next to a genuine movement. The finishing is great for a replica, but not Patek level.
- Avoid if: You want a “Beater” watch. Get a Submariner for that. This Clean Factory Rolex Daytona Le Mans is a special occasion piece.
9. Final Verdict – Is the Le Mans Worth It?
Yes. It is a technological milestone.
The Clean Factory Rolex Daytona Le Mans represents the peak of replica engineering in 2025. They didn’t just copy the look; they engineered a movement solution that shouldn’t exist at this price point.
If you are a collector who appreciates mechanics and vintage vibes, this is a must-have. Just treat it with respect.
