The Clean Factory (C Factory) Rolex Cosmograph Daytona M116519ln-0027 is one of the most talked-about replica watches in the high-end rep market. Known for its attention to detail, Clean Factory has gained a reputation for producing some of the closest replicas to genuine Rolex models. Today, we'll compare this replica watch with the authentic Rolex Daytona M116519ln-0027, highlighting key differences and similarities in materials, craftsmanship, and functionality.
1. Case & Materials
The genuine M116519ln-0027 is crafted from 18k white gold, giving it a distinct weight and premium feel. Clean Factory's version uses 904L stainless steel with PVD coating to mimic the white gold appearance. While the color is close, the replica watch is noticeably lighter due to the lack of precious metal.
The engravings on the case back (including the St. Bernard dog hallmark) are well-replicated, though minor imperfections remain, such as the dog's missing tuft of fur. The case shape, lugs, and pushers are nearly identical, with Clean Factory achieving 90%+ accuracy in dimensions.
2. Dial & Bezel
The "cement grey" dial is one of Clean Factory's strongest points. The vacuum PVD electroplating (4μm thickness) ensures the sunburst effect is preserved, unlike cheaper replicas that use thick paint. However, under certain lighting, the replica watch's dial appears slightly darker than the genuine.
The Cerachrom bezel is another highlight—Clean Factory specializes in ceramic components, and the platinum-filled numerals are almost indistinguishable from the real deal. The sapphire crystal is also well-executed, though some users report slightly more reflection than the genuine.
3. Bracelet & Clasp
The Oysterflex strap on the genuine model is a patented design with a metal core and elastomer coating. Clean Factory's version uses fluorine rubber with embedded steel sheets, which is comfortable but not as supple as the original.
The clasp is sourced from AR Factory, another high-end replica maker, and functions smoothly. However, the engravings lack the "750" hallmark found on the genuine white gold clasp.
4. Movement & Functionality
The genuine Caliber 4130 is a COSC-certified chronograph movement with 72h power reserve and -2/+2 sec/day accuracy. Clean Factory's Shanghai 4131 clone is a strong performer, offering ~75h power reserve but with -10/+15 sec/day accuracy.
The chronograph functions (start/stop/reset) work smoothly, and unlike older replicas with thick 7750 movements, Clean's version maintains the correct slim profile.
5. Wearability & Final Thoughts
On the wrist, the replica watch wears comfortably, though the weight difference (steel vs. gold) is noticeable. The overall finish and details are impressive for a fraction of the price (~$500-$800 vs. $38,000 for the genuine).
Pros of Clean Factory's Replica:
- 90-95% visual accuracy
- High-quality ceramic bezel & dial
- Functional chronograph with slim case
- Good value for money
Cons:
- Noticeably lighter (no white gold)
- Minor imperfections in engravings
- Oysterflex strap not as refined
- Movement accuracy not COSC-level
Discussion Questions:
1. How important is the weight difference (due to material) in making a replica watch feel "genuine"? Would adding tungsten weighting improve the experience, or is it unnecessary?
2. At ~2% of the genuine's price, does Clean Factory's replica offer 2% of the experience, or does it exceed expectations? Where do you draw the line between "good value" and "too close to genuine"?
