Clean Factory has established itself as a top-tier replica manufacturer, particularly for Rolex models. Their take on the coveted Daytona m126519ln-0006 (the "Cement Grey" white gold variant) is widely regarded as one of the most accurate replicas currently available. This review provides a thorough yet concise comparison between Clean Factory's version and the genuine Rolex, highlighting key similarities and differences.
Case & Materials
Genuine Rolex:
Material: Solid 18k white gold case
Weight: ~156g
Finish: High-polish with perfect brushing
Water Resistance: 100m
Clean Factory Replica:
Material: 904L stainless steel with PVD coating
Weight: ~106g (noticeably lighter)
Finish: Excellent polishing but slightly less refined
Water Resistance: ~50m (not fully tested)
Key Takeaway:The biggest giveaway is the weight difference (steel vs. gold). However, Clean Factory's PVD coating does an impressive job mimicking white gold's appearance.
Dial & Bezel Accuracy
Genuine:
Dial: Unique cement grey with perfect sunburst texture
Printing: Crisp, slightly raised lettering
Bezel: Black ceramic with platinum-filled numerals
Lume: Chromalight (long-lasting blue glow)
Clean Factory:
Dial: Nearly identical color and texture (reportedly from original molds)
Printing:Very sharp, minimal flaws
Bezel: High-quality ceramic with platinum-like coating (engraving depth is 98% accurate)
Lume: Strong but fades slightly faster than genuine
Key Takeaway: The dial and bezel are almost indistinguishable unless inspected closely under magnification.
Movement Comparison
Genuine Rolex Caliber 4131:
- Chronometer-certified (-2/+2 sec/day)
- Vertical clutch, column-wheel chronograph
- 72h power reserve
- Exquisite finishing (Geneva stripes, perlage)
Clean Factory Shanghai 4131 Clone:
- Functional chronograph (start/stop/reset works correctly)
- Claims ~72h power reserve (real-world ~60h)
- Decent accuracy (±5 sec/day in testing)
- Basic decoration (not as refined as genuine)
Key Takeaway:The movement is the biggest technical gap, but Clean Factory’s version is far better than older replica movements (like the 7750).
Bracelet & Clasp
Genuine Oysterflex:
- High-grade rubber with flexible metal core
- 18k white gold clasp with Easylink extension
- Perfect engravings and smooth operation
Clean Factory Version:
- Good-quality rubber but slightly stiffer
- PVD-coated steel clasp (looks close but not identical)
- Engravings are clean but not as deep
Key Takeaway: The strap is comfortable but doesn’t feel exactly like the genuine Oysterflex.
How It Stacks Up Against Other Factories
Verdict:Clean Factory leads in dial, bezel, and movement accuracy, making it the best overall choice among replicas.
Final Thoughts: Who Should Buy This?
Best For: Enthusiasts who want a near-identical Daytona for a fraction of the price.
Not For: Those who demand genuine materials and long-term Rolex reliability.
Discussion Questions:
1. Would you consider a high-end replica like Clean Factory’s, or is owning the genuine watch non-negotiable for you?
2. How much does movement finishing matter if the watch looks and functions almost the same?
